Allen-Bradley 20G11TE355AN0NNNNN PowerFlex 755 AC Drive — Detailed Product Specifications, Applications, Advantages, Related Models and Technical Guide

1. Product Introduction

The Allen-Bradley 20G11TE355AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for demanding industrial motor-control applications where high current capacity, reliable variable-speed operation, network integration, and flexible drive configuration are required.

This model belongs to the PowerFlex 755 family and is part of the large-frame 600 VAC three-phase drive range. It is a Frame 8, forced-air-cooled, open-type industrial AC drive with a rated current class of 355 A.

The drive is designed around a high-power motor-control architecture and provides three different duty classifications. Its Light Duty rating is 395 A / 400 HP, its Normal Duty rating is 355 A / 350 HP, and its Heavy Duty rating is 295 A / 300 HP.

These different ratings are important because industrial motors do not all operate under the same load conditions. A large centrifugal pump or fan may have a very different current and torque profile from a heavily loaded conveyor, mixer, crusher, or material-handling machine.

The 20G11TE355AN0NNNNN allows the same basic drive platform to be evaluated against these different application categories.

The drive also includes embedded EtherNet/IP, making it suitable for integration into an industrial automation network. This allows the drive to operate as part of a larger control architecture instead of functioning only as an independent frequency converter.

The catalog configuration includes AC input with DC terminals, forced-air cooling, an EMC-filtered configuration, and a CM jumper removed arrangement. Dynamic braking is not included, and the catalog configuration is supplied as Blank / No HIM.

This particular AN catalog configuration is an earlier PowerFlex 755 configuration. It has been discontinued, with 20G11TE355JN0NNNNN identified as the direct replacement configuration. The principal electrical capacity remains closely related, while the CM jumper configuration changes from removed to installed.

The product belongs to the PowerFlex 755 series, which is intended for industrial applications where large motors, sophisticated control, automation integration, and high-power electrical equipment are required.

The model is significantly larger than compact variable-frequency drives used for small machinery. A Frame 8 drive becomes a major component of the electrical installation, so mechanical support, cabinet construction, cooling, high-current wiring, grounding, and service access all need to be considered during system design.

3. PowerFlex 755 Series Overview

The PowerFlex 755 is a large industrial AC drive platform designed for applications where a conventional small VFD does not provide sufficient power capacity or system flexibility.

The series covers multiple voltage classes, output-current levels, frame sizes, duty ratings, and installation configurations.

The 20G11TE355AN0NNNNN belongs to the 600 VAC, three-phase group and uses a Frame 8 power structure.

The PowerFlex 755 architecture is particularly useful in industrial plants where the drive is part of an integrated automation system.

A typical system can include a PLC, industrial Ethernet network, HMI, process instrumentation, multiple motor drives, safety equipment, and supervisory software.

In this type of architecture, the PowerFlex 755 is not simply responsible for changing motor frequency. It becomes an integrated control device that can exchange commands, status information, operating data, faults, and diagnostics with the rest of the automation system.

4. Catalog Number Identification

The catalog number 20G11TE355AN0NNNNN represents a specific combination of voltage class, power level, frame, cooling, input architecture, filtering, CM configuration, braking configuration, and operator-interface configuration.

The major characteristics can be summarized as follows.

Catalog Characteristic	Description
Catalog Number	20G11TE355AN0NNNNN
Product Family	PowerFlex 755
Voltage Group	600 VAC
Phase	3 Phase
Current Class	355 A
Frame	8
Cooling	Air Cooled / Forced Air
Input	AC Input with Precharge and DC Terminals
Filtering	EMC Filter
CM Jumper	Removed
Dynamic Braking	None
HIM	Blank / No HIM
Communication	Embedded EtherNet/IP
Construction	Open Type

The AN configuration is especially relevant because it identifies the CM capacitor/jumper arrangement.

For this configuration, the CM jumper is removed.

The later JN configuration, 20G11TE355JN0NNNNN, uses the corresponding CM jumper installed arrangement.

This distinction matters when replacing equipment because common-mode and grounding-related configuration should be considered as part of the electrical system design rather than treated as an insignificant catalog-number difference.

The published PowerFlex 755 selection information identifies the 20G11TE355 configuration as 395 A / 400 HP Light Duty, 355 A / 350 HP Normal Duty, and 295 A / 300 HP Heavy Duty, with an equivalent Frame 8 size.

6. Duty Ratings Explained

The three duty ratings are one of the most important specifications to understand when selecting this drive.

Duty Classification	Output Current	Horsepower	Approx. kW Equivalent	Typical Load Type
Light Duty	395 A	400 HP	Approx. 298 kW	Variable-torque / lower overload demand
Normal Duty	355 A	350 HP	Approx. 261 kW	General industrial loads
Heavy Duty	295 A	300 HP	Approx. 224 kW	Higher-torque / demanding loads

The Light Duty rating provides the highest horsepower capability because many variable-torque applications, such as centrifugal pumps and fans, have load characteristics that allow the drive to operate at a higher motor horsepower within the applicable rating.

The Normal Duty rating is generally the central reference for general industrial motor applications.

The Heavy Duty rating is lower in horsepower because demanding constant-torque machinery can require substantially more current and overload capability.

For this reason, selecting a drive solely according to motor horsepower can be misleading. The motor nameplate current and actual load profile should always be checked.

7. Normal Duty Operation

The 355 A / 350 HP Normal Duty rating is the primary rating that defines the model’s position within the PowerFlex 755 600 VAC family.

A 350 HP industrial motor may be used in applications such as:

• Large pumps.
• Large fans.
• Conveyors.
• Compressors.
• Mixers.
• Blowers.
• Process machinery.
• Material-handling equipment.

However, the motor’s actual full-load current must still be checked.

Motor efficiency, power factor, voltage, operating speed, service factor, and motor design all influence the actual current required by the motor.

Therefore, a 350 HP motor is not automatically compatible with a 355 A drive under every possible operating condition.

8. Light Duty Operation

The 395 A / 400 HP Light Duty rating gives this model additional capacity when the application has a variable-torque or comparatively less demanding overload profile.

Large centrifugal pumps and fans are typical examples.

For these applications, the torque required by the machine changes with speed, and operating the motor below full speed can substantially change the process power requirement.

The Light Duty rating can therefore allow a larger motor to be controlled when the process characteristics fit the applicable drive rating.

9. Heavy Duty Operation

The 295 A / 300 HP Heavy Duty rating is important for more demanding applications.

Heavy-duty applications can include:

• Loaded conveyors.
• Mixers.
• Crushers.
• Material-handling machinery.
• Positive-displacement equipment.
• High-inertia machinery.
• Industrial processing equipment.

For these applications, acceleration and overload requirements can be more demanding than those of a centrifugal fan or pump.

If the motor application requires frequent acceleration, high starting torque, or significant overload operation, the Heavy Duty rating should be used as the principal selection reference.

10. Electrical Characteristics

The 20G11TE355AN0NNNNN is a 600 VAC three-phase AC drive.

The large Frame 8 architecture is designed for high-power industrial systems where significant motor current must be controlled reliably.

The drive uses AC input with precharge and provides DC terminals as part of its power architecture.

This configuration is suitable for installations where the drive is incorporated into a larger industrial electrical system and where the power architecture may include associated DC-bus arrangements.

11. Embedded EtherNet/IP Communication

The drive includes embedded EtherNet/IP.

This is one of the most important features from an automation perspective.

EtherNet/IP allows the drive to communicate with industrial controllers and other networked equipment.

A typical control structure might look like:

PLC → EtherNet/IP → PowerFlex 755 → Large AC Motor

The PLC can send commands and references to the drive.

The drive controls the motor.

The drive can then return operating status, current, frequency, faults, alarms, and other available data to the controller.

This approach reduces the need to treat the drive as an isolated device and makes it easier to coordinate multiple motors within a production system.

12. Typical Network Data

Depending on the control architecture and configuration, a networked drive may provide information such as:

• Start command.
• Stop command.
• Speed reference.
• Output frequency.
• Motor current.
• Drive status.
• Fault status.
• Alarm status.
• Operating state.
• Diagnostic information.
• Process-related operating data.

This is particularly useful in large industrial installations where operators need to know the condition of a high-power motor without physically accessing the drive cabinet.

13. Cooling System

The drive uses forced-air cooling.

At a 355 A current class, the thermal requirements are substantial.

Power semiconductor devices, control electronics, bus components, and other internal equipment generate heat during normal operation.

The installation therefore requires a carefully planned airflow path.

The cooling air must be able to enter the drive correctly, pass through the appropriate thermal components, and leave the installation without excessive recirculation.

Cabinet temperature must also be considered.

If the drive is installed inside a closed cabinet, the heat produced by the drive and other equipment must be included in the cabinet thermal calculation.

14. Mechanical Dimensions

The 20G11TE355AN0NNNNN is a Frame 8 PowerFlex 755 configuration.

The published PowerFlex 755 dimensional information gives the following reference dimensions for the open-type Frame 8 arrangement.

Mechanical Parameter	Approximate Value
Frame	8
Construction	IP00 / NEMA-UL Type Open
Height	2145 mm
Width	778 mm
Depth	425 mm
Overall Form	Large floor-mount industrial drive

These dimensions are reference dimensions for the Frame 8 open-type arrangement and should not be confused with a complete MCC-style cabinet.

The actual equipment installed in a project may occupy considerably more space once disconnect equipment, reactors, option bays, cable-entry areas, control equipment, ventilation systems, and maintenance clearances are included.

15. Weight

Because Frame 8 equipment is a large industrial power assembly, weight should be considered during both transportation and installation.

The published Frame 8 information identifies a maximum component weight of approximately 286 kg for the open AC-input drive assembly.

Complete cabinet configurations are substantially heavier.

Configuration	Approx. Dimensions	Approx. Weight
Open Frame 8 Drive Assembly	2145 × 778 × 425 mm	Approx. 286 kg maximum drive-assembly reference
IP20 / NEMA Type 1 Frame 8 Cabinet	2453 × 600 × 600/800 mm	Approx. 623 kg
IP54 / NEMA Type 12 Frame 8 Cabinet	2477 × 600 × 800 mm	Approx. 644 kg
IP54 Configuration with Filter Depth	2477 × 600 × 898 mm	Approx. 644 kg class

The cabinet weights are approximate and depend on the specific cabinet and options.

The 286 kg value represents the maximum component/drive-assembly reference for the open configuration rather than a universal shipping weight for every possible installation.

For project planning, the final mechanical drawing and equipment configuration should always be used.

16. Cabinet Installation

A Frame 8 PowerFlex 755 should be considered part of the overall electrical cabinet or equipment lineup.

The cabinet must provide sufficient room for:

• The drive assembly.
• Power cables.
• Control cables.
• Grounding conductors.
• Cooling airflow.
• Protective equipment.
• Disconnect equipment where required.
• Maintenance access.
• Communication equipment.
• Cable-entry arrangements.

The cabinet floor and mounting structure must also be capable of supporting the equipment weight.

Because the complete cabinet can weigh more than 600 kg, handling and transportation should be considered during the early engineering stage.

17. Roll-Out Handling

Large Frame 8–10 PowerFlex installations require careful mechanical handling.

A roll-out cart is specified for these large frame drives to assist with power wiring and cabinet mounting.

This is a practical consideration that is sometimes overlooked when a large VFD is selected only from its electrical rating.

The equipment may be relatively straightforward to specify electrically, but the installation team still needs an appropriate method for moving and positioning the power assembly safely.

18. Product Applications

18.1 Large Centrifugal Pumps

Large centrifugal pumps are among the most suitable applications for this drive.

Examples include:

• Water-treatment pumps.
• Cooling-water pumps.
• Process-water pumps.
• Irrigation pumps.
• Industrial circulation pumps.
• Large transfer pumps.

Variable-speed control allows the pump motor to operate according to process demand.

Instead of maintaining full motor speed continuously and regulating the process entirely through a valve, the drive can adjust motor speed directly.

This can provide smoother process regulation and may reduce energy consumption when lower operating speeds are sufficient.

18.2 Large Industrial Fans

Large fans and blowers are another strong application.

Typical examples include:

• Industrial ventilation.
• Combustion-air systems.
• Cooling systems.
• Exhaust systems.
• Dust-collection systems.
• Process-air systems.

The variable-torque characteristics of many fan systems can make the Light Duty rating especially useful, provided the motor and process fall within the applicable rating.

18.3 Large Conveyors

Conveyors often benefit from controlled acceleration.

Starting a large conveyor motor directly across the electrical supply can impose substantial mechanical and electrical stress.

A PowerFlex 755 can gradually accelerate the motor according to a programmed acceleration profile.

This can help reduce mechanical shock and provide a more controlled startup.

18.4 Mining and Bulk Material Handling

Large conveyors, pumps, fans, feeders, and processing machinery in mining and bulk-material applications can require high-power motor control.

The PowerFlex 755 platform provides a suitable architecture for integrating these motors into a larger automation system.

Heavy-duty equipment such as crushers should be evaluated carefully because torque and overload requirements can be substantially higher than those of variable-torque equipment.

18.5 Water and Wastewater Systems

Large pumping systems in water and wastewater facilities can benefit from variable-speed control.

The drive can be integrated into a control system that responds to:

• Pressure.
• Flow.
• Tank level.
• Demand.
• Process timing.

This makes it possible to coordinate motor speed with actual process conditions.

18.6 Large Compressors

Where the compressor design permits variable-speed operation, the PowerFlex 755 can provide controlled motor operation.

The drive can be used to manage acceleration, operating speed, and integration with the process controller.

Compressor applications require careful evaluation because compressor torque characteristics and allowable operating speeds vary considerably between technologies.

18.7 Large Mixers

Industrial mixers and agitators can involve significant inertia.

The drive can provide a controlled acceleration profile, reducing the abrupt mechanical loading that could occur with direct starting.

For heavily loaded mixers, the Heavy Duty rating should be used for the principal drive-sizing calculation.

18.8 Process Machinery

The PowerFlex 755 is also suited to large process machines.

Examples include:

• Material-processing machinery.
• Production lines.
• Large winding systems.
• Industrial handling equipment.
• Process pumps.
• Large blowers.
• Specialized production machines.

The ability to integrate the drive into an industrial network is especially valuable for these applications.

19. Main Product Advantages

High Current Capacity

The 355 A Normal Duty rating places the drive in a high-power industrial category.

It is intended for large motors and machines where compact VFDs are no longer practical.

The drive can support up to 400 HP under its Light Duty classification, making it suitable for a broad range of large variable-speed applications.

Flexible Duty Ratings

The three duty classifications are a significant advantage.

A single Frame 8 platform can be evaluated for variable-torque, general industrial, or demanding heavy-duty applications.

This simplifies the selection process because the same product family can cover several different load profiles.

Industrial Network Integration

Embedded EtherNet/IP allows the drive to become part of a modern automation architecture.

For large industrial plants, this can be more useful than simply having a local keypad.

The drive can be monitored and commanded from the central automation system.

Controlled Acceleration

Large motors can create high starting currents and mechanical shock.

Variable-frequency control allows the motor to accelerate smoothly.

This can be beneficial for conveyors, pumps, fans, mixers, and other large machinery.

Improved Process Control

Variable-speed operation allows the motor to respond to actual process requirements.

This can improve the controllability of pumps, fans, conveyors, and process machinery.

High-Power Industrial Architecture

Frame 8 construction provides a robust physical platform for high-power applications.

It is designed for floor-mounted industrial installations rather than compact machine mounting.

Diagnostic Capability

The PowerFlex 755 platform provides drive operating and diagnostic information that can be incorporated into the control and maintenance strategy.

For a large industrial motor, early identification of abnormal conditions can be valuable because unexpected downtime can affect a significant portion of a production process.

20. Advantages for Plant Automation

In a large manufacturing or process facility, the drive can function as an intelligent motor-control node.

A PLC can command the drive.

An HMI can display the operating state.

The drive can provide diagnostic information.

The overall system can coordinate multiple motors.

This architecture is particularly valuable when several large motors work together.

For example, a production system could use one drive for a conveyor, another for a process pump, another for a fan, and another for a mixer.

The automation controller can coordinate the entire process through the network.

21. Advantages for Energy Management

Variable-speed operation can also support more efficient process operation.

A motor does not necessarily need to operate at full speed all the time.

For variable-torque loads, reducing speed can significantly reduce the power required by the machine.

This is one reason why large pump and fan systems are common applications for high-power VFDs.

Actual energy savings depend on the machine, operating profile, process requirements, motor efficiency, and system design, so savings should be calculated from the actual application rather than assumed solely from the presence of a VFD.

22. Advantages for Mechanical Systems

Controlled acceleration and deceleration can help reduce mechanical shock.

This can be particularly valuable for:

• Long conveyors.
• Large fans.
• Pumps.
• Mixers.
• High-inertia machines.
• Material-handling equipment.

A gradual speed change can reduce sudden torque transfer through couplings, shafts, gearboxes, belts, and other mechanical components.

23. CM Jumper Removed Configuration

The 20G11TE355AN0NNNNN is specified with the CM jumper removed.

This configuration should be considered when designing or replacing a drive in an existing installation.

The common-mode configuration can influence how the drive interacts with the grounding and electrical system.

For this reason, engineers should not assume that a JN and AN drive are completely interchangeable simply because their output current and horsepower ratings are similar.

The later 20G11TE355JN0NNNNN configuration has the CM jumper installed.

The electrical system should be checked whenever changing from one configuration to the other.

24. Filtering

The model uses an EMC filter configuration.

Filtering can help control conducted electrical noise and support electromagnetic compatibility within an industrial system.

However, EMC performance is not determined by the drive alone.

The final result depends on:

• Motor cable type.
• Cable length.
• Shielding.
• Grounding.
• Cabinet bonding.
• Cable routing.
• Separation between power and control wiring.
• Installation environment.

A well-designed system therefore needs to consider the complete drive installation rather than simply specifying a filtered drive.

25. Dynamic Braking

The catalog configuration has:

Dynamic Braking: None

This is important for applications involving rapid deceleration.

When a large motor slows down, the motor can return energy to the drive DC bus.

If the process requires frequent or very rapid stopping, an appropriate braking solution may be necessary.

Possible approaches can include:

• Longer deceleration ramps.
• External braking equipment.
• Mechanical braking.
• Regenerative solutions.
• Application-specific energy management.

The correct approach depends on motor inertia, stopping time, cycle frequency, load characteristics, and process requirements.

26. HIM Configuration

The model is configured as:

Blank / No HIM

This means the catalog configuration does not include a local HIM as part of the specified product.

The drive can instead be controlled and monitored through the industrial automation system or separately selected operator-interface equipment.

This arrangement is often suitable for large cabinet installations where the operator normally interacts with the equipment through a centralized HMI.

27. Installation Considerations

Installation Area	Main Requirement
Mounting	Rigid structural support
Cabinet	Large industrial enclosure
Cooling	Adequate forced-air ventilation
Power Wiring	High-current conductors sized for the installation
Grounding	Correct protective and functional grounding
EMC	Appropriate cable routing and bonding
Service Access	Adequate maintenance clearance
Handling	Suitable mechanical handling equipment
Environment	Protection from excessive contamination
Heat Dissipation	Cabinet thermal calculation
Cable Entry	Adequate space for large power cables
Network	Industrial Ethernet planning

The mechanical and electrical requirements should be considered together.

A large Frame 8 drive cannot be treated as a small component that is simply added to an already completed cabinet.

28. Recommended Same-Series Models

The following five models are closely related to the 20G11TE355AN0NNNNN and are useful for comparison within the same 600 VAC PowerFlex 755 family.

20G11TE510AN0NNNNN	600 VAC, 3 PH	545 A / 550 HP	510 A / 500 HP	425 A / 450 HP	8	CM Jumper Removed

These models provide a logical progression around the 355 A configuration. The published 600 VAC selection data lists the same progression of current and horsepower ratings.

29. Related Model — 20G11TE295AN0NNNNN

The direct replacement designation is particularly important when the original AN model is being used in an existing installation. The replacement model should still be checked against the actual electrical and mechanical configuration before installation.

36. Five Popular Models from the Same Brand

The following are useful examples of other popular Allen-Bradley PowerFlex models. They are not direct replacements for the 20G11TE355AN0NNNNN.

They are included because they represent different parts of the same broad industrial drive portfolio.

Model	Series	Voltage Class	Phase	Current Class	Typical Power/Application	Approx. Dimensions	Approx. Weight
25B-D024N114	PowerFlex 525	480 VAC class	3 PH	24 A class	Compact industrial motor control	Compact / frame dependent	Approx. 5–10 kg class
25B-D6P0N114	PowerFlex 525	480 VAC class	3 PH	6 A class	Small machine and pump/fan control	Compact / frame dependent	Approx. 2–4 kg class
20F11NC3P4JA0NNNNN	PowerFlex 753	480 VAC class	3 PH	3.4 A class	Small industrial drive applications	Frame dependent	Approx. 5–10 kg class
20F11ND077AA0NNNNN	PowerFlex 753	480 VAC class	3 PH	77 A class	Medium/high-power industrial control	Frame dependent	Approx. 30–70 kg class
25C-D043N114	PowerFlex 523	480 VAC class	3 PH	43 A class	Compact industrial machinery	Compact / frame dependent	Approx. 5–10 kg class

The dimensions and weights for these smaller models vary by frame, enclosure, and exact configuration, so the values in this comparison are intentionally given as approximate classes rather than as exact shipping weights.

37. PowerFlex 525 Comparison

The PowerFlex 525 family is intended for much smaller motor applications.

Compared with the 20G11TE355AN0NNNNN, a PowerFlex 525 is dramatically smaller and has a much lower current rating.

This makes the PowerFlex 525 appropriate for compact machinery, conveyors, pumps, fans, and general-purpose applications where a large Frame 8 drive would be excessive.

The 20G11TE355AN0NNNNN should be considered when the motor is several hundred horsepower and the electrical system requires a high-current industrial drive.

38. PowerFlex 523 Comparison

The PowerFlex 523 is another compact drive family.

It is useful for smaller industrial machines where simple variable-speed control is required.

The 20G11TE355AN0NNNNN is designed for a completely different application scale.

A 355 A Frame 8 drive requires significantly more mechanical and electrical infrastructure than a compact PowerFlex 523.

39. PowerFlex 753 Comparison

The PowerFlex 753 occupies a more industrial position than the compact PowerFlex families and shares the broader PowerFlex 750-Series architecture.

However, the 20G11TE355AN0NNNNN is still a significantly larger Frame 8 configuration.

When a project requires a very large motor, high current, large cabinet construction, and integrated industrial networking, the PowerFlex 755 architecture is an appropriate product family to evaluate.

40. Application Suitability Table

Application	Suitability	Recommended Duty
Large Centrifugal Pump	Excellent	Light Duty / Normal Duty
Large Cooling Fan	Excellent	Light Duty
Industrial Blower	Excellent	Light Duty / Normal Duty
Water Pump	Excellent	Light Duty / Normal Duty
Wastewater Pump	Excellent	Light Duty / Normal Duty

Material Handling	Very Good	Normal Duty / Heavy Duty
Crusher	Application Dependent	Heavy Duty
Large Process Machine	Very Good	Application Dependent
Small Machine	Poor Match	Compact drive recommended

The duty classification should always be selected according to the actual machine load and motor requirements.

41. Motor Selection Requirements

Before selecting the drive for a particular motor, engineers should collect the motor’s complete nameplate information.

Motor Parameter	Importance
Motor Voltage	Must match the drive system
Motor Full-Load Current	Primary current-sizing reference
Motor Horsepower	Defines approximate power requirement
Motor Frequency	Determines operating frequency range
Motor Speed	Important for process-speed requirements
Motor Service Factor	Important for application margin
Torque Characteristic	Determines LD/ND/HD suitability
Acceleration Time	Influences current demand
Load Inertia	Important for acceleration and deceleration
Motor Cable Length	Important for output-side system design
Motor Insulation	Important for VFD operation
Ambient Conditions	Affects thermal performance

The actual motor current should be compared with the applicable drive duty rating rather than selecting the drive solely by horsepower.

42. Conveyor Application Example

A large conveyor is a good example of why duty classification matters.

A conveyor may appear straightforward because the motor simply rotates a belt.

In practice, however, the motor may need to accelerate a very large mass of material and belt.

The starting torque can therefore be significant.

If the conveyor is heavily loaded and requires frequent acceleration, the Heavy Duty rating may become the governing selection factor.

The PowerFlex 755 can provide a controlled acceleration profile so that the motor does not immediately apply full torque to the mechanical system.

43. Pump Application Example

A centrifugal pump presents a different load profile.

The torque requirement typically changes significantly with speed.

This makes variable-frequency control particularly useful.

The drive can adjust motor speed according to pressure or flow requirements.

If the pump normally operates below maximum speed, the drive can avoid running the motor at full speed unnecessarily.

This type of application is one of the main reasons why the Light Duty rating can support a higher horsepower motor than the Normal Duty rating.

44. Fan Application Example

Large industrial fans often have similar variable-torque characteristics.

The 395 A / 400 HP Light Duty rating can therefore be useful for appropriately sized fan applications.

The drive can control the fan according to process demand.

For example, a ventilation system may need maximum airflow during one operating condition but significantly less airflow at another time.

Variable-speed operation allows the motor to respond directly to those requirements.

45. Maintenance Considerations

Large industrial drives should be included in a planned preventive-maintenance program.

Typical maintenance activities include:

• Visual inspection.
• Cooling-fan inspection.
• Airflow-path inspection.
• Cabinet cleaning.
• Power-terminal inspection.
• Grounding inspection.
• Cable inspection.
• Network connection inspection.
• Fault-history review.
• Temperature monitoring.
• Inspection for unusual vibration or noise.

The maintenance interval depends on operating hours, environmental conditions, process requirements, duty cycle, and plant maintenance policy.

46. Environmental Considerations

The drive is an open-type industrial product.

This means that the surrounding installation must provide the appropriate level of environmental protection.

Particular attention should be given to:

• Dust.
• Moisture.
• Conductive particles.
• Oil mist.
• Corrosive gases.
• Excessive temperature.
• Restricted airflow.
• Condensation.

The enclosure and environmental-control strategy should be designed around the actual plant environment.

47. Power Cable Planning

At 355 A, power-cable selection is an important part of the installation.

Cable size depends on:

• Installation method.
• Conductor material.
• Ambient temperature.
• Number of conductors.
• Cable grouping.
• Allowable temperature.
• Local electrical code.
• Motor current.
• Cable length.

The power cables also need to be routed appropriately in relation to control and communication wiring.

A large industrial drive should therefore be included in the electrical layout from the beginning rather than added after the cabinet design is complete.

48. Grounding and EMC Considerations

The filtered configuration and CM jumper arrangement make correct grounding particularly important.

The drive, cabinet, motor, and associated equipment should be connected using an appropriate grounding and bonding strategy.

The objective is not only personnel safety but also correct high-frequency current paths and electromagnetic compatibility.

Improper cable routing or grounding can create unnecessary electrical noise that may affect sensitive control and communication equipment.

49. Braking Requirements

Because dynamic braking is not included in the standard catalog configuration, applications involving rapid stopping should be reviewed separately.

The engineering team should calculate:

• Motor inertia.
• Load inertia.
• Initial speed.
• Final speed.
• Required stopping time.
• Number of stops per hour.
• Regenerated energy.
• Mechanical braking requirements.

A longer deceleration ramp may be sufficient for some applications.

Other applications may require an external braking or regenerative solution.

50. Lifecycle and Replacement Consideration

The 20G11TE355AN0NNNNN has a discontinued lifecycle status, with the discontinuation associated with the earlier AN configuration.

The identified direct replacement is 20G11TE355JN0NNNNN.

This is important for procurement because the original AN model should generally be treated as an existing-equipment or legacy catalog reference rather than the preferred choice for a new project.

The JN configuration should be evaluated when replacing the original unit.

The principal difference to pay attention to is the CM jumper configuration.

Lifecycle Item	Information
Original Model	20G11TE355AN0NNNNN
Product Family	PowerFlex 755
Status	Discontinued
Direct Replacement	20G11TE355JN0NNNNN
Original CM Configuration	Jumper Removed
Replacement CM Configuration	Jumper Installed
Current Selection Strategy	Evaluate JN replacement for new procurement

The replacement should still be checked against the existing cabinet, motor, grounding system, control architecture, firmware, network arrangement, and mechanical installation before being installed.

51. AN and JN Configuration Comparison

These models are all closely related Frame 8 configurations in the 600 VAC three-phase PowerFlex 755 range.

53. Mechanical Reference for the Related Frame 8 Models

Because these related models use the same general Frame 8 mechanical platform, the following reference dimensions can be used for preliminary cabinet planning.

Mechanical Parameter	Frame 8 Reference
Open-Type Height	2145 mm
Open-Type Width	778 mm
Open-Type Depth	425 mm
Open Drive Assembly Weight	Up to approx. 286 kg
IP20 Cabinet Height	2453 mm

58. Overall Product Assessment

The Allen-Bradley 20G11TE355AN0NNNNN PowerFlex 755 AC Drive is a large industrial variable-frequency drive designed for high-power motor applications.

Its 600 VAC three-phase input, 355 A Normal Duty rating, 395 A Light Duty rating, 295 A Heavy Duty rating, Frame 8 architecture, forced-air cooling, embedded EtherNet/IP, EMC filtering, and CM jumper removed configuration make it suitable for demanding industrial installations.

The drive is particularly well suited to large pumps, fans, conveyors, compressors, mixers, water systems, process machinery, and material-handling equipment.

For variable-torque applications, the 400 HP Light Duty capability makes the drive attractive for large fans and centrifugal pumps.

For general industrial applications, the 350 HP Normal Duty rating is the central specification.

For demanding constant-torque applications, the 300 HP Heavy Duty rating provides the appropriate reference point.

The embedded EtherNet/IP capability is another major advantage. It allows the drive to become part of an integrated automation system where the motor, PLC, HMI, process instruments, and other equipment work together.

The physical size of the drive is also important.

With a Frame 8 open-type reference dimension of approximately 2145 mm high × 778 mm wide × 425 mm deep, this is substantial electrical equipment.

The open drive assembly can weigh up to approximately 286 kg, while a complete IP20 cabinet arrangement can be around 623 kg, and an IP54 cabinet arrangement can be around 644 kg.

Consequently, mechanical handling, cabinet construction, ventilation, floor loading, power-cable routing, and maintenance access should all be planned before installation.

The model’s AN configuration also deserves attention because it identifies the CM jumper removed arrangement.

For replacement purposes, the closely related 20G11TE355JN0NNNNN is the direct replacement configuration and uses the CM jumper installed arrangement.

Therefore, when replacing an existing 20G11TE355AN0NNNNN, the electrical system should be reviewed rather than treating the replacement as a simple current-for-current exchange.

For new applications, the JN replacement configuration should normally be evaluated first because the original AN catalog configuration has been discontinued.

Within the same 600 VAC Frame 8 PowerFlex 755 family, the 20G11TE295AN0NNNNN, 20G11TE395AN0NNNNN, 20G11TE435AN0NNNNN, 20G11TE460AN0NNNNN, and 20G11TE510AN0NNNNN provide a useful range of lower and higher current capacities.

For substantially smaller motors, PowerFlex 523 and PowerFlex 525 products can provide a more compact solution.

For medium industrial applications, PowerFlex 753 products offer another option within the broader PowerFlex architecture.

Overall, the 20G11TE355AN0NNNNN can be described as a large-frame, high-current, 600 VAC PowerFlex 755 industrial AC drive intended for large automated motor-control systems.

Its strongest application areas are large variable-speed pumps, industrial fans, conveyors, process equipment, water and wastewater systems, compressors, mixers, and other high-power machinery where controlled motor operation and industrial network integration are important.

The most important engineering rule is to select the drive from the actual motor nameplate current and application duty—not from horsepower alone.

When the motor current, torque characteristics, overload requirements, acceleration profile, braking requirements, ambient conditions, cabinet arrangement, and communication requirements are all properly evaluated, the PowerFlex 755 architecture provides a strong platform for large-scale industrial motor control.
