1. Product Introduction

The Allen-Bradley 20G11TE395AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where substantial current capacity, variable-speed operation, network connectivity, and flexible drive control are required.

This model is a 600 VAC, three-phase, air-cooled, Frame 8 drive with an open-type construction, embedded EtherNet/IP communication, AC input with DC terminals, EMC filtering, and a CM jumper removed configuration.

The drive has a 395 A class power structure and supports three different application duty ratings. Its Light Duty rating is approximately 435 A / 450 HP, its Normal Duty rating is approximately 395 A / 400 HP, and its Heavy Duty rating is approximately 329 A / 350 HP.

This makes the model suitable for large motors used in demanding industrial machinery. It can be applied to conveyors, pumps, fans, blowers, compressors, mining equipment, bulk material handling systems, process machinery, and other high-power applications where precise motor speed control is required.

The 20G11TE395AN0NNNNN is also designed for integration into an industrial automation system. Its embedded EtherNet/IP capability allows the drive to communicate with the wider control architecture, making it possible to coordinate motor operation, speed commands, status information, alarms, and diagnostic data with the plant control system.

Because this is a large Frame 8 drive, the physical installation requirements are considerably greater than those of compact variable-frequency drives. Cabinet dimensions, ventilation, cable routing, grounding, mechanical handling, service access, and heat dissipation should all be considered during system design.

The three duty ratings are important when selecting this drive.

The 395 A catalog designation should not be interpreted as the maximum current under every operating condition. The drive’s rated current changes according to the selected duty classification.

For Normal Duty applications, the drive is rated at approximately 395 A and 400 HP. For Heavy Duty operation, the continuous current rating is approximately 329 A, corresponding to approximately 350 HP. For Light Duty applications, the drive can be applied at approximately 435 A and 450 HP.

---

4. Duty Ratings

Duty Rating	Continuous Output Current	Approx. Motor Rating	Approx. Power	Typical Load
Light Duty	435 A	450 HP	336 kW	Variable-torque / lower overload demand
Normal Duty	395 A	400 HP	298 kW	General industrial machinery
Heavy Duty	329 A	350 HP	261 kW	Higher overload and demanding mechanical loads

The correct duty rating should be selected from the actual motor nameplate current and application load profile.

For example, a 400 HP motor operating continuously under a relatively stable load may be appropriate for the Normal Duty rating, while a mechanically demanding application with frequent acceleration, high starting torque, or repeated overload conditions may require a different drive selection.

Motor horsepower should therefore be considered together with motor current, overload requirements, acceleration time, mechanical inertia, operating cycle, and environmental conditions.

---

5. Approximate Dimensions and Weight

The 20G11TE395AN0NNNNN uses a Frame 8 construction. The following figures are useful engineering reference values for the applicable Frame 8 drive arrangement.

Mechanical Parameter	Approximate Value
Frame Size	8
Open-Type Height	2145 mm
Open-Type Width	778 mm
Open-Type Depth	425 mm
Approx. Open Drive Assembly Weight	286 kg
IP20 / NEMA Type 1 Cabinet Height	2453 mm
IP20 / NEMA Type 1 Cabinet Width	600 mm
IP20 / NEMA Type 1 Cabinet Depth	600 or 800 mm
Approx. IP20 Cabinet Weight	623 kg
IP54 / NEMA Type 12 Cabinet Height	2477 mm
IP54 / NEMA Type 12 Cabinet Width	600 mm
IP54 / NEMA Type 12 Cabinet Depth	800 mm
Approx. IP54 Cabinet Weight	644 kg

The dimensions and weights above should be regarded as reference values for the applicable Frame 8 construction. A complete cabinet assembly can be considerably heavier than the basic drive because it may include enclosure structures, disconnect equipment, bus components, filters, power wiring, control equipment, and other accessories.

The actual installation drawing should always be used for final mechanical planning.

At approximately 286 kg for the open drive assembly, this is not equipment that should be handled like a compact wall-mounted drive. Proper lifting, positioning, cabinet installation, and service access must be planned in advance.

---

6. Electrical Characteristics

The 20G11TE395AN0NNNNN is designed for a 600 VAC three-phase industrial power system.

This voltage class is commonly used in large industrial motor installations where motor power is high enough that reducing current becomes an important consideration for the electrical distribution system.

The drive accepts AC power and provides controlled variable-frequency output to the connected three-phase motor.

The power structure includes DC terminals, which can be useful in applications where the drive’s DC bus architecture needs to be considered as part of the overall system.

The input arrangement also includes precharge functionality as part of the drive’s power architecture.

Because of the high current level, upstream electrical protection and distribution equipment must be appropriately sized and coordinated with the drive.

---

7. CM Jumper Removed Configuration

A particularly important feature of the 20G11TE395AN0NNNNN is its CM jumper removed configuration.

The CM configuration relates to common-mode behavior and the electrical relationship between the drive’s filtering and grounding arrangement.

This configuration is significant in applications where EMC, common-mode current, motor insulation stress, grounding, and system architecture must be carefully coordinated.

The CM jumper removed configuration can be advantageous when the electrical system has been designed around a specific grounding and EMC arrangement.

It is important to distinguish this model from the related 20G11TE395JN0NNNNN, which uses the corresponding CM jumper installed configuration.

The two models have the same general 600 VAC, Frame 8, 395 A class PowerFlex 755 platform, but the CM configuration is different.

For this reason, the catalog number should be checked carefully when replacing an existing drive.

---

8. EMC Filter

The 20G11TE395AN0NNNNN is configured with an EMC filter.

Electromagnetic compatibility is an important consideration in large industrial installations because variable-frequency drives generate high-frequency switching components during normal operation.

These electrical components can interact with:

• Instrumentation
• Control systems
• Industrial networks
• Sensors
• PLC systems
• Communication wiring
• Other variable-frequency drives
• Measurement equipment
• Sensitive electronic devices

The EMC filter forms part of the overall noise-control strategy.

It should be combined with proper grounding, bonding, cable routing, motor cable selection, shield termination, and separation of power and control wiring.

The filter itself should not be regarded as a complete substitute for proper installation practices.

---

9. Embedded EtherNet/IP Communication

The integrated EtherNet/IP capability is one of the most useful features of the PowerFlex 755 architecture.

In a modern production facility, the drive can operate as part of the larger automation system rather than functioning as an isolated motor controller.

Depending on the control architecture, the network can be used to exchange information such as:

• Start and stop commands
• Speed references
• Operating status
• Actual speed
• Drive alarms
• Drive faults
• Diagnostic information
• Motor operating information
• Control commands
• Process data
• Maintenance information

For large production lines with multiple drives, this can simplify system integration and improve visibility of motor operation.

The communication capability is particularly valuable when the drive is installed in a remote electrical room while operators and control engineers need access to operating information from a central control system.

---

10. No Standard HIM

The model is supplied in a Blank / No HIM configuration.

HIM stands for Human Interface Module and normally provides a local interface for configuration, monitoring, adjustment, and troubleshooting.

A no-HIM configuration is practical when the drive is intended to be integrated into a centralized control architecture.

In such systems, operators may interact with the drive through an HMI, PLC, supervisory control system, or engineering workstation rather than using a permanently installed local keypad.

This configuration can also help maintain a cleaner cabinet arrangement when local operator interaction at the drive itself is not required.

---

11. Cooling System

The 20G11TE395AN0NNNNN is an air-cooled drive.

At several hundred amperes of motor current, heat generation becomes a major engineering consideration.

The drive enclosure and surrounding electrical room must provide sufficient airflow and heat removal.

The installation should account for:

• Ambient temperature
• Heat generated by the drive
• Cabinet ventilation
• Airflow direction
• Dust accumulation
• Humidity
• Altitude
• Contamination
• Service access

Poor ventilation can increase internal temperature and may shorten component life or cause thermal protection to operate.

For this reason, cooling should be included in the initial cabinet and room design rather than added as an afterthought.

---

12. Product Applications

Large Conveyor Systems

Large conveyor systems are one of the most natural applications for this drive.

Conveyors used in mining, aggregate processing, ports, warehouses, steel production, cement production, and bulk material handling can require motors in the hundreds of horsepower.

A variable-frequency drive allows the motor to accelerate and decelerate in a controlled manner.

This can reduce mechanical stress on:

• Belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Conveyor structures

Controlled speed also makes it easier to match conveyor operation with production requirements.

---

Mining Equipment

Mining environments often involve large motors, demanding mechanical loads, long operating periods, and harsh operating conditions.

The 20G11TE395AN0NNNNN can be considered for applications such as:

• Large conveyors
• Material handling
• Pumps
• Ventilation fans
• Process equipment
• Crushers
• Bulk material systems
• Mine dewatering equipment

The final drive selection should take into account the actual mechanical load, environmental conditions, motor data, and required overload performance.

---

Large Pumps

Large pumps can benefit significantly from variable-speed operation.

Instead of running a motor continuously at full speed, the drive can adjust motor speed to match process demand.

Typical applications include:

• Water transfer
• Industrial water systems
• Cooling water
• Process circulation
• Wastewater systems
• Irrigation
• Industrial utilities
• High-capacity pumping stations

The ability to regulate pump speed can provide better process control and may reduce unnecessary energy consumption when full pump capacity is not required.

---

Large Fans and Blowers

Industrial fans and blowers can require hundreds of horsepower, particularly in process plants, mining facilities, steel plants, cement plants, and large ventilation systems.

Variable-speed control can adjust airflow according to actual demand.

Applications include:

• Industrial ventilation
• Furnace ventilation
• Combustion air
• Exhaust systems
• Dust collection
• Process air
• Cooling systems
• Large HVAC installations

The PowerFlex 755 architecture provides a suitable platform for these larger motor-driven systems.

---

Compressors

Large compressors require controlled motor operation and can have demanding starting and acceleration requirements.

The drive can provide controlled acceleration and adjustable motor speed while also communicating with the wider process-control system.

This makes the platform useful for industrial compressed-air systems and certain process-compressor applications.

---

Process Machinery

The drive can also be used on large process machines where motor speed needs to be controlled according to production requirements.

Examples include:

• Mixers
• Agitators
• Material-processing equipment
• Production lines
• Feed systems
• Large machine systems
• Material-handling equipment
• Industrial production machinery

---

13. Advantages of the 20G11TE395AN0NNNNN

High Current Capacity

The drive’s 395 A Normal Duty rating places it firmly in the high-power industrial category.

It can support large motors without requiring multiple smaller drives to be combined simply to achieve the necessary current capacity.

This makes the drive particularly useful for large centralized motor systems.

---

Three Application Duty Levels

The three duty ratings provide considerable flexibility.

Duty	Current	HP	Approx. kW
Light Duty	435 A	450 HP	336 kW
Normal Duty	395 A	400 HP	298 kW
Heavy Duty	329 A	350 HP	261 kW

This allows engineers to match the drive to the actual load rather than relying solely on the motor horsepower.

---

Industrial Ethernet Integration

Embedded EtherNet/IP provides a straightforward way to integrate the drive into an industrial control system.

For larger plants, this can simplify communication between the drive and the control system while providing operators with more complete information about motor operation.

---

High-Voltage Motor Applications

The 600 VAC class makes the drive appropriate for large industrial motor systems.

Higher-voltage motor systems can be advantageous in large plants because motor current can be managed more effectively compared with equivalent low-voltage high-power systems.

---

Large-Frame Construction

The Frame 8 platform is built for substantial industrial equipment.

It is physically larger and heavier than compact drives, but that size reflects the drive’s high-current capability.

For large industrial equipment, the larger power structure can be more appropriate than attempting to adapt smaller drive platforms to applications for which they were not designed.

---

Filtered Configuration

The integrated EMC filter provides an important part of the drive’s electromagnetic compatibility strategy.

This is valuable in industrial plants where drives operate alongside instrumentation, communications systems, PLCs, sensors, and other electronic equipment.

---

Flexible Automation Architecture

The PowerFlex 755 platform can be incorporated into a broader automation system.

This is useful for production plants where the motor controller must interact with process logic, machine sequencing, operator interfaces, and maintenance systems.

---

14. Installation Requirements

The Frame 8 construction requires more installation planning than compact drives.

Adequate room should be provided for:

• Power cable connections
• Control wiring
• Network connections
• Cooling airflow
• Maintenance
• Component replacement
• Inspection
• Safe electrical isolation
• Mechanical handling

Large Frame 8–10 drives may require a roll-out cart to assist with power wiring and cabinet mounting.

The physical location should also provide adequate access for maintenance personnel.

---

15. Grounding and Cable Considerations

At this current level, proper grounding and cable installation are extremely important.

The motor cable must be selected according to the motor rating, cable length, installation method, environmental conditions, and applicable drive requirements.

Particular attention should be paid to:

• Motor cable construction
• Shielding
• Cable length
• Ground conductor arrangement
• Motor-frame bonding
• Drive-frame bonding
• Cabinet grounding
• Control-cable routing
• Network cable separation
• High-frequency grounding paths

The CM jumper removed configuration should also be considered when developing the grounding and EMC strategy.

---

16. Maintenance Considerations

Large variable-frequency drives should be included in the plant’s preventive maintenance program.

Maintenance personnel should periodically inspect:

• Cooling paths
• Fans
• Electrical connections
• Power terminals
• Grounding connections
• Cabinet ventilation
• Dust accumulation
• Signs of overheating
• Network connections
• Control wiring
• Environmental conditions

The actual maintenance interval should be based on operating hours, environmental conditions, plant maintenance procedures, and equipment criticality.

A drive controlling a critical conveyor or process pump may justify a more structured maintenance and spare-parts strategy than a non-critical machine.

---

20G11TE460AN0NNNNN	600 VAC, 3 PH	8	510 A / 500 HP	460 A / 500 HP	395 A / 400 HP	CM Jumper Removed

These models provide a useful range around the 20G11TE395AN0NNNNN.

The 295 A-class and 355 A-class versions are useful when the motor current is lower, while the 435 A-class and 460 A-class versions provide additional capacity for larger motors.

The 20G11TE395JN0NNNNN is the closest configuration match when the same power rating is required but the CM jumper installed configuration is preferred.

---

18. Mechanical Comparison of Related Models

20. Five Popular Allen-Bradley Models for Broader Comparison

For customers who want to compare the PowerFlex 755 with other popular Allen-Bradley drive families, the following models represent different power ranges and applications.

Model	Series	Voltage Class	Phase	Current Class	Typical Application	Dimensions / Weight
25B-D024N114	PowerFlex 525	480 VAC class	3 PH	24 A	General industrial machinery	Compact frame; size and weight depend on frame
25B-D6P0N114	PowerFlex 525	480 VAC class	3 PH	6 A	Small pumps, fans and machines	Compact frame; size and weight depend on frame
20F11NC3P4JA0NNNNN	PowerFlex 753	480 VAC class	3 PH	3.4 A class	Flexible industrial motor control	Frame-dependent
20F11ND077AA0NNNNN	PowerFlex 753	480 VAC class	3 PH	77 A class	Medium/high-power industrial equipment	Frame-dependent
25C-D043N114	PowerFlex 523	480 VAC class	3 PH	43 A class	Compact general-purpose applications	Compact frame; size and weight depend on frame

These five models are not direct electrical replacements for the 20G11TE395AN0NNNNN.

The PowerFlex 525 and PowerFlex 523 families are more compact and are generally intended for smaller motor applications.

The PowerFlex 753 occupies a different position, providing a flexible industrial drive architecture for a broad range of applications.

The PowerFlex 755 is more appropriate when the application requires very high current capacity, large motors, advanced control architecture, and integration into a substantial industrial automation system.

---

21. Application Selection Guide

Application	Suitability	Reason
Large mining conveyor	Excellent	High current and large motor capacity
Bulk material conveyor	Excellent	Controlled acceleration and speed
Large industrial pump	Excellent	Variable-speed process control
Large fan	Excellent	Adjustable airflow and motor speed
Industrial blower	Excellent	High-power motor operation
Large compressor	Very Good	Controlled acceleration and process integration

The 20G11TE395AN0NNNNN is best used where the motor and mechanical load justify a high-power Frame 8 drive.

Selecting an oversized drive for a small motor can increase equipment cost, cabinet space, installation complexity, and maintenance requirements without providing a practical benefit.

---

22. Important Engineering Selection Factors

---

23. Why the Model Is Suitable for Large Industrial Systems

The 20G11TE395AN0NNNNN combines several features that become increasingly important as motor size increases.

A large industrial motor is not simply a larger version of a small motor installation.

As motor power increases, electrical distribution, cable sizing, thermal management, mechanical stress, fault protection, grounding, and automation integration become more significant.

The PowerFlex 755 architecture addresses this class of application with a large-frame drive platform designed around substantial current capacity.

The embedded EtherNet/IP interface also allows the drive to become part of a larger automation system.

This combination makes the drive suitable for production facilities where motor control is integrated with PLCs, HMIs, supervisory systems, process instrumentation, and maintenance systems.

---

24. Energy and Process Control Benefits

Variable-speed operation can provide significant process advantages in applications where motor speed does not need to remain constant.

For pumps and fans, for example, process demand can vary considerably throughout the operating day.

Running the motor at a reduced speed when full capacity is not required can provide a more controlled operating condition than simply cycling a fixed-speed motor on and off or restricting flow mechanically.

For conveyors, speed control can allow production throughput to be matched to the rest of the process.

For fans and blowers, speed adjustment can allow airflow to be matched to process requirements.

The actual energy savings depend on the application, motor efficiency, load characteristics, operating schedule, system design, and control strategy.

---

25. Reliability and Industrial Use

The PowerFlex 755 platform is intended for industrial environments where drive operation is part of a larger production system.

The large-frame architecture provides the physical capacity required for high-current applications, while network communication provides access to operating and diagnostic information.

For critical applications, reliability is not only a matter of drive construction. Proper installation, cooling, grounding, cable selection, electrical protection, environmental control, and maintenance all contribute to long-term performance.

A correctly selected drive operating within its specified conditions can provide a strong foundation for continuous industrial motor operation.

---

26. Maintenance Strategy

For a drive of this size, preventive maintenance should be treated as part of the production strategy.

Recommended inspection areas include:

Maintenance Area	Inspection Focus
Cooling	Fans, airflow and ventilation
Power Connections	Loose or overheated connections
Grounding	Ground conductors and bonding
Cabinet	Dust, moisture and contamination
Motor Cable	Insulation, termination and routing
Control Wiring	Connections and physical condition
Network	Communication connections and status
Environment	Temperature, humidity and contamination
Mechanical Installation	Mounting and enclosure condition
Diagnostics	Faults, alarms and operating history

The actual maintenance schedule should be determined by the plant’s operating environment and equipment criticality.

28. Overall Product Assessment

The Allen-Bradley 20G11TE395AN0NNNNN is a substantial high-power PowerFlex 755 drive intended for large industrial motor applications.

Its 600 VAC three-phase configuration, Frame 8 construction, 395 A Normal Duty rating, 435 A Light Duty rating, and 329 A Heavy Duty rating give it the capacity required for motors in the approximately 350–450 HP range, depending on the actual duty classification.

One of its strongest characteristics is the combination of high electrical capacity with industrial automation connectivity.

The embedded EtherNet/IP interface allows the drive to communicate with the plant control system, making it easier to integrate motor control, status monitoring, alarms, diagnostics, and process information into a centralized automation architecture.

The CM jumper removed configuration is another important characteristic of this specific catalog number.

This configuration distinguishes it from the related 20G11TE395JN0NNNNN. Although the two models have essentially the same primary voltage, current, horsepower, frame, and communication characteristics, their CM configurations are different and should be selected according to the electrical installation requirements.

The EMC filter is also useful for industrial environments where electromagnetic compatibility must be carefully managed.

From a mechanical perspective, the Frame 8 construction is large and heavy. The approximate open drive assembly weight of 286 kg and the larger cabinet configurations mean that mechanical handling, floor loading, ventilation, power cable access, and maintenance space must be planned carefully.

For large conveyors, pumps, fans, blowers, compressors, mining systems, bulk material handling equipment, and process machinery, the model provides a combination of power capacity and control flexibility that is well matched to the application.

The most closely related alternatives are the 20G11TE295AN0NNNNN, 20G11TE355AN0NNNNN, 20G11TE395JN0NNNNN, 20G11TE435AN0NNNNN, and 20G11TE460AN0NNNNN.

For a broader comparison across the same brand, the PowerFlex 525, PowerFlex 523, and PowerFlex 753 families offer smaller or differently positioned drive solutions for applications where a Frame 8 PowerFlex 755 would be unnecessarily large.

Overall, the 20G11TE395AN0NNNNN is best viewed as a high-capacity industrial motor-control platform for large equipment rather than simply a high-horsepower inverter. Its main value comes from the combination of high current capability, multiple duty ratings, 600 VAC operation, large-frame construction, embedded EtherNet/IP, EMC filtering, and flexible integration into a plant-wide automation system.
