2. Brand

The product brand is Allen-Bradley.

Allen-Bradley is widely associated with industrial automation equipment, including programmable controllers, motor control products, drives, operator interfaces, and industrial networking equipment.

For this product, the important product identification is the Allen-Bradley PowerFlex 755 platform.

The PowerFlex 755 family is aimed at larger and more demanding industrial motor-control applications where a compact general-purpose variable-frequency drive may not provide the required combination of power, control functions, communication capability, and system integration.

---

3. Product Series

The 20G14NF098JN0NNNNN belongs to the PowerFlex 755 series within the broader PowerFlex 750-Series family.

Product Classification	Identification

Family	PowerFlex 750-Series
Series	PowerFlex 755
Product Class	Architecture-class AC drive
Voltage Group	690 VAC
Cooling	Air Cooled
Construction	Open Type
Frame	Frame 6

The PowerFlex 755 platform is designed for industrial equipment where the drive is normally part of a complete machine or plant-control system.

It is especially useful when motor control needs to be integrated with PLC logic, HMI operation, process control, industrial communications, diagnostics, and machine-level sequencing.

---

4. Product Introduction

The 20G14NF098JN0NNNNN is designed for large industrial motor applications requiring a high-voltage, three-phase variable-frequency drive.

With a 98 A Normal Duty rating and 90 kW Normal Duty power rating, it occupies a substantial position within the 690 VAC PowerFlex 755 range.

The drive can regulate motor speed and provide controlled acceleration and deceleration, allowing the motor to operate according to the needs of the machine rather than simply running continuously at fixed line frequency.

This can be particularly useful in process equipment where the required motor speed changes according to production demand.

The model is an air-cooled Frame 6 open-type drive, which means it is generally intended to be installed inside an appropriately designed electrical cabinet or control enclosure.

The cabinet becomes part of the overall installation and must provide suitable environmental protection, cooling, electrical clearance, grounding, cable routing, and maintenance access.

6. Normal Duty Rating

The most prominent rating of this model is its 98 A Normal Duty output capability.

The corresponding Normal Duty motor power rating is approximately 90 kW.

This makes the drive suitable for large industrial motors where the load profile does not exceed the specified Normal Duty requirements.

Typical Normal Duty applications include:

• Large centrifugal pumps.
• Industrial fans.
• Blowers.
• HVAC process equipment.
• Water circulation systems.
• Process machinery.
• Conveyors with suitable load characteristics.
• Material-handling equipment.
• Large rotating machinery.

The 90 kW rating should be considered a starting point for selection rather than the only selection criterion.

The actual motor nameplate current should always be compared with the drive output-current rating.

---

7. Heavy Duty Rating

The drive also provides an approximately 82 A Heavy Duty rating, corresponding to approximately 75 kW Heavy Duty operation.

Duty Classification	Current	Power
20G14NF098JN0NNNNN – Normal Duty	98 A	90 kW
20G14NF098JN0NNNNN – Heavy Duty	82 A	75 kW

Heavy Duty operation is particularly relevant when the machine requires greater torque or more demanding overload performance.

Examples can include:

• Heavily loaded conveyors.
• High-inertia machinery.
• Certain process machines.
• Material-handling systems.
• Applications with demanding acceleration.

The actual application should be evaluated according to motor current, load profile, acceleration time, deceleration time, overload requirement, and operating environment.

---

8. 690 VAC Three-Phase Operation

The 20G14NF098JN0NNNNN is designed for a 690 VAC three-phase system.

This voltage class is commonly associated with larger industrial motors.

For high-power motors, a higher voltage allows the required motor power to be delivered at a lower current than would be necessary at a lower voltage.

That can provide advantages in large electrical systems, including practical conductor sizing and reduced current-related losses.

The 690 VAC rating is therefore one of the major reasons this model belongs in the high-power industrial-drive category.

---

9. DC Input with Precharge

The model uses a DC Input with Precharge configuration.

This is an important distinction from a conventional AC-input drive.

In a DC-bus system, the drive receives its power from the appropriate DC bus architecture rather than directly performing the same type of AC line conversion found in a standard AC-input configuration.

The precharge arrangement controls the initial charging of the drive’s DC-link capacitors.

This is especially important in high-power systems because the DC bus contains substantial energy-storage capacitance.

A controlled precharge sequence helps prevent an uncontrolled initial charging current.

This configuration can therefore be attractive in:

• Common DC bus systems.
• Multi-drive systems.
• Coordinated drive installations.
• Large industrial machinery.
• Systems where DC bus power architecture is deliberately designed into the equipment.

---

10. Air-Cooled Design

The 20G14NF098JN0NNNNN is an air-cooled PowerFlex 755 drive.

Air cooling is a practical solution for many industrial installations because it avoids the complexity of liquid cooling while still providing the thermal performance required for high-power electronics.

However, the cooling system depends heavily on the surrounding cabinet design.

The installation should provide:

• Adequate airflow.
• Correct airflow direction.
• Sufficient ventilation.
• Suitable cabinet temperature.
• Clean cooling passages.
• Appropriate clearance.
• Regular fan inspection.
• Protection against excessive contamination.

A drive that is correctly sized electrically can still experience thermal problems if the cabinet is poorly ventilated.

---

11. Frame 6 Mechanical Configuration

The drive uses Frame 6 construction.

Frame size is important when designing the cabinet because it affects the physical installation area, mounting arrangements, cable routing, ventilation, and maintenance access.

Mechanical Parameter	Approximate Value
Model / Catalog Number	20G14NF098JN0NNNNN
Frame	Frame 6
Height	665.5 mm
Width	308 mm
Depth	346.4 mm
Approx. Weight	14.51 kg*
Cooling	Air Cooled
Enclosure	Open Type

The stated dimensions should be regarded as the approximate drive envelope.

They should not be treated as the complete cabinet footprint.

Additional space is normally required for:

• Power connections.
• DC bus connections.
• Grounding.
• Motor connections.
• Control wiring.
• Network cables.
• Cable bending radius.
• Cooling airflow.
• Maintenance access.
• Safe working clearance.

---

12. Open-Type Enclosure

The drive uses an Open Type enclosure configuration.

This construction is particularly useful for OEM machine builders and system integrators because the drive can be incorporated into a custom control cabinet.

The final enclosure should provide the necessary environmental protection for the application.

A suitable cabinet design should consider:

Cabinet Design Factor	Importance
20G14NF098JN0NNNNN physical envelope	Must fit the cabinet
Airflow	Required for cooling
Ambient temperature	Must remain within the applicable range
Dust protection	Important in industrial environments
Moisture	Must be controlled
Electrical clearance	Required for safe installation
Grounding	Important for safety and EMC
Cable routing	Important for reliable operation
Maintenance access	Required for service
Heat dissipation	Important for continuous operation

---

13. Filtering and CM Jumper

This configuration is specified as Filtered, CM Jumper Installed.

Filtering is useful in installations where electromagnetic compatibility is an important consideration.

Variable-frequency drives use high-frequency switching to control the motor. That switching naturally produces electrical noise components.

Proper filtering, grounding, shielding, cable routing, and cabinet design help manage these effects.

The CM jumper should be considered as part of the complete grounding and electrical-system design.

It should not be changed casually because the correct configuration depends on the system’s grounding arrangement and installation requirements.

---

14. Dynamic Braking Configuration

One of the important differences between the JN0 model and certain closely related PowerFlex 755 configurations is the dynamic-braking arrangement.

For 20G14NF098JN0NNNNN, the configuration is specified with no internal dynamic-braking transistor and no internal dynamic-braking resistor.

Braking Feature	Specification
Model / Catalog Number	20G14NF098JN0NNNNN
Internal DB Transistor	No
Internal DB Resistor	No
Regenerative Energy Handling	Application-dependent
External Braking Solution	May be required depending on application
Rapid Deceleration	Requires application evaluation

This point matters for applications with high inertia or frequent stopping.

When a motor decelerates, mechanical energy can flow back toward the drive DC bus.

If the application generates significant regenerative energy, the system must have an appropriate method of managing that energy.

Therefore, the JN0 configuration should not automatically be selected for an application simply because it has sufficient motor power.

The stopping profile must also be considered.

---

15. Blank / No HIM Configuration

The drive uses a Blank / No HIM configuration.

HIM means Human Interface Module.

A local HIM is useful when technicians or operators need to configure and monitor the drive directly from the front of the unit.

The no-HIM configuration is more appropriate when the machine already has centralized operator controls.

For example, a machine can use an HMI to display:

• Motor speed.
• Output current.
• Output frequency.
• Drive status.
• Faults.
• Warnings.
• Process values.
• Run commands.
• Speed references.

This approach can produce a cleaner cabinet and a more centralized operator interface.

---

16. Communication and Automation

The PowerFlex 755 platform is intended to operate as part of an industrial automation system.

For the 20G14NF098JN0NNNNN, embedded Ethernet capability can be used as part of the control and monitoring architecture.

A typical automation system may include:

PLC → Industrial Network → PowerFlex 755 → Motor

The PLC can manage:

• Start.
• Stop.
• Speed reference.
• Direction.
• Fault reset.
• Operating mode.

The drive can provide information such as:

• Actual speed.
• Output frequency.
• Output current.
• Running status.
• Fault status.
• Warning status.
• Diagnostic information.

This makes the drive well suited to centralized industrial automation.

---

17. Typical Product Applications

17.1 Large Pumps

Large industrial pumps are one of the most natural applications for this drive.

Variable-speed operation allows the pump motor speed to follow process demand.

Applications can include:

• Water circulation.
• Cooling water.
• Process water.
• Industrial utilities.
• Water treatment.
• Chemical process systems.
• Large fluid-transfer systems.

For centrifugal pump applications, speed control can also provide significant process-control benefits compared with operating a motor continuously at full speed.

---

17.2 Large Fans

Large industrial fans can benefit from variable-speed control.

Typical applications include:

• Industrial ventilation.
• Exhaust systems.
• Furnace air systems.
• Cooling systems.
• Process ventilation.
• Large HVAC systems.

Instead of controlling airflow entirely through mechanical dampers, the motor speed can be adjusted according to process requirements.

---

17.3 Blowers

Industrial blowers can require large motor power, making the PowerFlex 755 platform appropriate for many such applications.

Examples include:

• Process-air systems.
• Industrial exhaust.
• Combustion-air systems.
• Pneumatic process systems.
• Waste-treatment systems.

---

17.4 Conveyors

Large conveyors often require controlled acceleration and deceleration.

A variable-frequency drive allows the conveyor motor to start smoothly instead of applying full line-frequency operation immediately.

This can reduce mechanical shock and make the machine easier to coordinate with other equipment.

---

17.5 Compressors

Large compressors can require substantial motor power and careful control.

The drive can be used where the compressor package has been designed for variable-speed operation.

Compressor applications should receive detailed engineering attention because their torque and overload characteristics may differ substantially from those of pumps and fans.

---

17.6 Mixers and Agitators

Industrial mixers and agitators often require variable operating speed.

The drive can allow the process system to change motor speed according to material characteristics or production requirements.

---

17.7 Material Handling

Material-handling equipment can use the PowerFlex 755 to provide:

• Controlled acceleration.
• Controlled deceleration.
• Adjustable speed.
• Machine synchronization.
• PLC integration.
• Fault monitoring.

The availability of a high-power 690 VAC configuration makes the drive suitable for larger material-handling equipment.

---

17.8 Process Machinery

Large process machines can benefit from integrated variable-speed control.

Typical examples include:

• Production machinery.
• Manufacturing equipment.
• Processing lines.
• Large rotating equipment.
• Industrial utility machinery.

---

18. Main Product Advantages

High-Power 690 VAC Platform

The 690 VAC class makes this drive appropriate for large industrial motor systems.

It is designed for a level of power that would be beyond the practical range of many compact machine drives.

---

98 A Normal Duty Capacity

The 98 A Normal Duty rating provides substantial motor-control capability.

With a Normal Duty rating of approximately 90 kW, it is well suited to large pumps, fans, blowers, conveyors, and process machinery.

---

82 A Heavy Duty Capacity

The 82 A Heavy Duty rating gives the drive useful flexibility for applications requiring more demanding operating conditions.

This makes it possible to use the same drive platform across different machine load profiles.

---

DC Input with Precharge

The DC-input arrangement is a significant advantage in common-bus and DC-bus applications.

It allows the drive to be incorporated into power architectures where the DC bus is an intentional part of the system design.

---

Air-Cooled Construction

Air cooling provides a practical thermal-management method for industrial cabinet installations.

For many plants, forced-air cooling is easier to maintain than liquid cooling.

---

Frame 6 Architecture

Frame 6 provides a relatively substantial mechanical platform appropriate for high-power applications.

The frame also provides a standardized physical architecture within the PowerFlex 755 family.

---

Embedded Ethernet Capability

Industrial Ethernet integration is useful when the drive must communicate with a centralized automation system.

It can reduce the need for extensive hardwired control signals and provides a convenient method for monitoring drive information.

---

No-HIM Configuration

The blank/no-HIM configuration is useful where operators already have access to a centralized HMI.

It can also simplify the front-panel appearance of the cabinet.

---

Filtered Configuration

The filtered configuration is useful where electrical-noise management is important.

This is particularly relevant to larger industrial installations with long motor cables and multiple pieces of electronic equipment.

---

19. Five Recommended Same-Series Models

The following models are closely related 690 VAC PowerFlex 755 configurations.

They are useful when the required motor power is lower or higher than the 90 kW Normal Duty rating of the 20G14NF098JN0NNNNN.

20G14NF142JN0NNNNN	142 A	132 kW	119 A	110 kW	690 VAC, 3 Ph	Frame 6 class	Air Cooled	Approx. 665.5 × 308 × 346.4 mm	Approx. 14.51 kg*

*The weight value should be treated as an approximate catalog/product-listing figure and verified against the exact physical revision before mechanical handling or cabinet calculations.

---

20. Same-Series Power Comparison

Model	Normal Duty Power	Heavy Duty Power	Suitable Motor Range	General Position
20G14NF050JN0NNNNN	45 kW	37 kW	Around 45 kW ND	Lower-power alternative
20G14NF061JN0NNNNN	55 kW	45 kW	Around 55 kW ND	Medium-power alternative
20G14NF082JN0NNNNN	75 kW	55 kW	Around 75 kW ND	Below target model
20G14NF098JN0NNNNN	90 kW	75 kW	Around 90 kW ND	Target model
20G14NF119JN0NNNNN	110 kW	90 kW	Around 110 kW ND	Higher-power alternative

This progression is useful when designing multiple machines around the same PowerFlex 755 platform.

For example, an OEM may use the 61 A model on one machine, the 82 A model on another, and the 98 A model on a larger machine while keeping a broadly consistent drive architecture.

24. PowerFlex 755 Compared With PowerFlex 525

The PowerFlex 525 is generally associated with smaller and more compact machine applications.

The PowerFlex 755 is designed for larger industrial systems and higher-power applications.

The difference becomes particularly significant when the motor voltage reaches the 690 VAC class.

For a 90 kW Normal Duty application, the 20G14NF098JN0NNNNN is much closer to the intended application range than a compact PowerFlex 525.

The PowerFlex 525 is more attractive when the machine requires:

• Smaller physical size.
• Lower power.
• Simpler installation.
• Compact cabinet design.
• General-purpose variable-speed control.

The PowerFlex 755 is more appropriate when the system requires:

• Higher power.
• 690 VAC operation.
• Advanced drive functionality.
• Larger industrial motors.
• Common-bus integration.
• More extensive automation integration.
• Larger machine architecture.

---

25. Cabinet Installation

Because the drive is open type, cabinet design is an important part of the overall installation.

The cabinet should have enough space for the drive and its associated wiring.

A practical cabinet design should include space for:

• Power connections.
• DC bus connections.
• Motor wiring.
• Control wiring.
• Communication cables.
• Grounding.
• Cooling airflow.
• Service access.
• Component inspection.
• Cable bending radius.

The cabinet should also be designed so that hot exhaust air does not simply circulate back into the drive’s cooling inlet.

---

26. Thermal Management

Thermal management becomes increasingly important as drive power increases.

Potential heat sources include:

• Drive power electronics.
• DC bus components.
• Cooling fans.
• Contactors.
• Reactors.
• Transformers.
• Other drives.
• Power supplies.
• Motor cable losses.

The cabinet’s total heat load should be evaluated.

A high-power drive should not be installed in a small sealed enclosure without considering the thermal consequences.

---

27. Motor Selection

The drive should be selected using the actual motor nameplate data.

Motor Parameter	Importance
Rated Voltage	Must match the motor/system configuration
Rated Current	Critical for drive sizing
Rated Power	Useful preliminary sizing value
Rated Frequency	Required for correct motor operation
Rated Speed	Important for speed-control requirements
Power Factor	Influences current
Efficiency	Influences system loading
Service Factor	Relevant to overload evaluation
Motor Type	Determines control requirements
Insulation System	Important for PWM operation
Cable Length	Can influence electrical and EMC behavior
Load Type	Determines duty requirements

The most important practical point is that 98 A is the key Normal Duty current rating.

A 90 kW motor with a current requirement above the drive rating should not be operated simply because its nominal kW value appears to match.

---

28. Applications Requiring Extra Engineering

Although the drive is suitable for many large industrial applications, certain machines require more detailed engineering.

These include:

• High-inertia machines.
• Rapid acceleration applications.
• Rapid deceleration applications.
• Hoists.
• Vertical lifting systems.
• Frequent regenerative operation.
• Machines requiring repeated emergency stopping.
• Large compressors.
• High-torque process machinery.
• Hazardous-area equipment.
• High-temperature environments.
• Heavy dust environments.

The absence of an internal dynamic-braking transistor in the JN0 configuration is particularly important for applications requiring significant braking energy management.

---

29. Maintenance

Regular maintenance can help protect the long-term performance of the drive.

Important inspection points include:

• Cooling fan operation.
• Air passages.
• Cabinet ventilation.
• Dust accumulation.
• Electrical connections.
• Grounding.
• DC bus connections.
• Motor cables.
• Control wiring.
• Communication cables.
• Fault history.
• Alarm history.
• Cabinet temperature.

The maintenance schedule should be adjusted according to the actual operating environment.

A clean electrical room will normally place less contamination stress on the drive than a dusty manufacturing or processing environment.

---

30. Spare-Part Selection

When replacing this drive, the complete catalog number should be checked.

The following identification is important:

20G14NF098JN0NNNNN

A visually similar PowerFlex 755 drive should not automatically be assumed to be interchangeable.

Replacement Check	Required Configuration
Catalog Number	20G14NF098JN0NNNNN
Voltage	690 VAC
Phase	3 Phase
Input	DC Input with Precharge
Normal Duty	98 A / 90 kW
Heavy Duty	82 A / 75 kW
Cooling	Air Cooled
Frame	Frame 6
Enclosure	Open Type
Filtering	Filtered
CM Jumper	Installed
Dynamic Braking	No Internal DB Transistor
HIM	Blank / No HIM
Approx. Dimensions	665.5 × 308 × 346.4 mm
Approx. Weight	14.51 kg*

This is especially important because the closely related JA0 and JN0 configurations can have different option arrangements.

---

31. JN0 vs. JA0 Configuration

The distinction between the two configurations is worth highlighting.

Feature	20G14NF098JN0NNNNN	20G14NF098JA0NNNNN
Series	PowerFlex 755	PowerFlex 755
Voltage	690 VAC	690 VAC
Normal Duty	98 A / 90 kW	98 A / 90 kW
Heavy Duty	82 A / 75 kW	82 A / 75 kW
Cooling	Air Cooled	Air Cooled
Frame	Frame 6	Frame 6
Input	DC Input with Precharge	DC Input with Precharge
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
HIM	Blank / No HIM	Blank / No HIM
Dynamic Braking	No Internal DB Transistor	DB Transistor Configuration
Main Difference	No internal DB transistor	DB transistor included

This is one of the most important details when identifying a replacement.

The two catalog numbers have the same basic voltage and current class, but the braking configuration is different.

For equipment where dynamic braking is important, selecting the wrong suffix can result in an unsuitable replacement.

---

32. Key Advantages for OEMs

For OEM machine builders, the 20G14NF098JN0NNNNN offers several practical advantages.

The 690 VAC rating allows the machine builder to use the drive with larger industrial motors.

The PowerFlex 755 platform provides a consistent architecture for machines that require more advanced motor control.

The DC input with precharge configuration is particularly useful when the machine uses a common DC bus.

The no-HIM arrangement is useful when the machine has a dedicated HMI.

The air-cooled construction also makes the drive practical for many conventional industrial cabinets.

---

33. Key Advantages for System Integrators

System integrators can benefit from using a consistent PowerFlex platform across multiple machines.

Advantages may include:

• Familiar drive architecture.
• Consistent parameter management.
• Easier commissioning.
• Easier troubleshooting.
• Common maintenance practices.
• Simplified technician training.
• Consistent PLC integration.
• Easier spare-parts planning.

This can be particularly valuable in plants containing many variable-speed motors.

36. Overall Product Assessment

The 20G14NF098JN0NNNNN is a high-power industrial drive designed for demanding 690 VAC three-phase motor-control applications.

Its 98 A Normal Duty / 90 kW rating makes it particularly suitable for large industrial motors.

The 82 A Heavy Duty / 75 kW rating provides additional flexibility for applications where the load profile requires a more demanding duty classification.

The DC input with precharge configuration is one of the defining characteristics of the model and makes it especially relevant to systems built around a DC bus or common DC bus.

The air-cooled Frame 6 construction is practical for cabinet-based industrial installations, while the open-type design gives OEMs and system integrators freedom to build the surrounding electrical enclosure according to the machine requirements.

The filtered configuration with CM jumper installed is useful in installations where electrical noise and grounding considerations need to be managed carefully.

The Blank / No HIM arrangement makes sense for centralized automation systems in which operators use an HMI or supervisory control system rather than interacting directly with the drive.

One of the most important characteristics of this particular JN0 version is its lack of an internal dynamic-braking transistor. This differentiates it from certain closely related PowerFlex 755 configurations and should be checked carefully whenever the drive is being selected for high-inertia or rapid-deceleration machinery.

For large pumps, fans, blowers, conveyors, process machinery, material-handling systems, and other large rotating equipment, the model offers a strong combination of power capacity, industrial integration, and cabinet flexibility.

For a smaller motor, a lower-current PowerFlex 755 model may be more economical.

For a larger motor, the 119 A and 142 A configurations provide additional capacity.

For compact 480 VAC machinery, a PowerFlex 525 configuration may be a more practical solution.

The most important engineering rule is to select the drive based on actual motor current, voltage, duty classification, load characteristics, acceleration/deceleration requirements, braking requirements, cabinet temperature, and installation conditions, rather than relying on the motor kW rating alone.

In practical terms, the 20G14NF098JN0NNNNN can be described as a 690 VAC, 98 A Normal Duty, 90 kW PowerFlex 755 industrial AC drive with DC input and precharge, air-cooled Frame 6 construction, open enclosure, filtered configuration, embedded Ethernet capability, and no internal dynamic-braking transistor.

It is best suited to large industrial automation systems where reliable variable-speed motor control needs to be integrated into a larger machine or plant-control architecture.
