5. Dimensions and Weight

Because the 20G11JF960JN0NNNNN is a Frame 9 high-power packaged drive, its dimensions and weight are substantially greater than those of ordinary wall-mounted variable-frequency drives.

The catalog configuration identifies an 800 mm deep MCC-style enclosure.

A listed mechanical reference gives a cabinet depth of approximately 78.35 inches, equivalent to approximately 1,990 mm for the relevant overall dimensional direction. The final physical arrangement can vary according to the packaged cabinet configuration, wiring bay, option bay and installation arrangement.

For this reason, dimensional information should be treated as an engineering reference rather than as a substitute for the final mechanical drawing.

The weight is particularly significant. A listed complete packaged configuration is approximately 1,246 kg.

This is a major difference from smaller PowerFlex products. Transportation, lifting, floor loading, cabinet positioning and maintenance access must therefore be planned as part of the installation.

Mechanical Parameter	Reference Value
Frame	9
Enclosure	IP54 / Type 12
Construction	MCC style
Nominal enclosure depth class	800 mm
Listed overall dimensional direction	Approx. 1,990 mm
Width	Configuration-dependent
Height	Configuration-dependent
Approx. Weight	1,246 kg
Cooling	Forced air
Maintenance clearance	Must be established from final installation drawing
Lifting requirement	Required for large packaged configuration

For engineering procurement, the 1,246 kg figure should be regarded as a practical reference for a complete packaged configuration, while the final shipping weight should be confirmed against the actual ordered package.

6. Electrical Rating

The 20G11JF960JN0NNNNN is a 690 VAC, three-phase, 960 A high-power drive.

The current rating is one of its most important characteristics.

At 960 A, the drive is designed for motors with very large electrical power requirements.

The Normal Duty rating is approximately 900 kW, while the Heavy Duty rating is approximately 800 kW.

This distinction is important when selecting the drive.

A pump or fan may operate primarily as a variable-torque load and therefore use the Normal Duty rating.

A conveyor, crusher or high-inertia machine may require substantially greater overload capability during acceleration. Such applications should be evaluated against the Heavy Duty rating rather than relying only on the motor’s nominal kW value.

7. Duty Ratings

Duty	Approximate Power Rating	Typical Application
Light Duty	1000 kW class	Lower-overload applications
Normal Duty	900 kW	Pumps, fans and moderate industrial loads
Heavy Duty	800 kW	Conveyors, high-inertia machinery and higher-torque loads

The 900 kW Normal Duty rating is particularly important for this model.

The 800 kW Heavy Duty rating provides a lower power ceiling when the application requires greater overload capability.

Therefore, an 850 kW motor might be suitable in a Normal Duty application but would not necessarily be appropriate for a Heavy Duty application.

Motor full-load current, overload duration, acceleration time and actual torque requirements should always be checked.

8. Product Introduction

The PowerFlex 755 series is intended for applications that require a combination of motor-speed control, process control, industrial communication and advanced drive functionality.

The 20G11JF960JN0NNNNN is one of the high-power configurations in this family.

It is intended to control large three-phase motors while providing a communication interface for integration with an industrial automation system.

Instead of operating the motor only through a conventional contactor or starter, the drive can continuously regulate motor speed.

This makes it possible to adapt motor output to process demand.

For example, a large pump can operate at a lower speed when the required flow decreases.

A large fan can reduce speed when ventilation requirements are reduced.

A conveyor can accelerate gradually rather than applying full mechanical torque immediately.

This flexibility is the main reason high-power VFDs are used in modern industrial installations.

9. Main Product Features

9.1 960 A High-Current Output

The 960 A output capability makes this drive suitable for very large industrial motors.

It is intended for applications where current requirements are far beyond the range of compact and medium-size drives.

This high current capacity is particularly useful for:

• Large pumps
• Large fans
• Mining conveyors
• Material-handling systems
• Process machinery
• Industrial ventilation
• Large rotating equipment

9.2 900 kW Normal Duty

The approximately 900 kW Normal Duty rating provides a large operating range.

This makes the model appropriate for applications where the load does not continuously require heavy overload capability.

Variable-torque applications are particularly suitable.

9.3 800 kW Heavy Duty

The approximately 800 kW Heavy Duty rating provides additional flexibility for applications that require more demanding motor operation.

Heavy-duty selection should be based on the actual application rather than simply the motor nameplate.

Acceleration torque, inertia, speed range and overload requirements should all be considered.

9.4 690 VAC Three-Phase Input

The 690 VAC class is appropriate for large industrial motor systems.

Higher motor voltage allows large motor power to be transmitted at a more manageable current level than would be required at lower voltage.

This is useful for large industrial power-distribution systems.

9.5 IP54 / Type 12 Enclosure

The IP54 / Type 12 enclosure provides protection appropriate for many industrial environments.

It is designed for use in industrial electrical areas where dust, dirt and incidental moisture may be present.

The rating does not mean that the equipment can be installed without consideration of corrosive gases, conductive dust, direct washdown, salt spray or severe humidity.

Environmental conditions should be evaluated for every installation.

9.6 Forced-Air Cooling

A 900 kW-class drive generates substantial heat.

The drive therefore uses forced-air cooling.

The referenced configuration uses a backward-curved centrifugal fan with approximately 1,805 m³/h airflow.

The cooling system must have sufficient intake and exhaust clearance.

Poor ventilation can increase operating temperature and may result in thermal protection events.

10. Product Applications

10.1 Large Pumping Systems

Large pumping systems are one of the most suitable applications for this drive.

Examples include:

• Water-treatment pumps
• Cooling-water pumps
• Process pumps
• Industrial circulation pumps
• Mining water pumps
• Large utility pumps
• Slurry-related pumping systems
• High-capacity water-transfer systems

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

This provides more flexible control than operating the pump continuously at a fixed speed.

10.2 Large Fans

Large industrial fans can require hundreds of kilowatts of motor power.

The 20G11JF960JN0NNNNN can provide variable-speed control for such systems.

Typical applications include:

• Mine ventilation
• Furnace exhaust
• Industrial ventilation
• Dust collection
• Process exhaust
• Large air-handling systems
• Combustion-air systems
• Large cooling systems

10.3 Large Conveyors

Conveyors are another important application.

A long conveyor can have substantial mechanical inertia.

The drive can provide a controlled acceleration profile.

This can help reduce mechanical stress on:

• Conveyor belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Drive pulleys
• Mechanical structures

Controlled acceleration can also make it easier to coordinate multiple conveyor sections.

10.4 Mining Applications

The 960 A rating makes the drive suitable for large mining equipment.

Potential applications include:

• Ore conveyors
• Large fans
• Water pumps
• Material-handling equipment
• Crushing systems
• Processing equipment
• Ventilation systems

Mining installations may require additional environmental and safety considerations, especially where dust, temperature, altitude or hazardous-area requirements are involved.

10.5 Cement and Aggregate Plants

Large cement and aggregate facilities often contain high-power motors.

Potential applications include:

• Conveyors
• Fans
• Pumps
• Crushers
• Material-handling equipment
• Process machinery

The drive’s network communication capability can also make it suitable for centralized plant control.

10.6 Metals Processing

Large metal-processing systems may require substantial motor power.

Variable-speed control can be used for:

• Fans
• Pumps
• Conveyors
• Roll systems
• Material handling
• Auxiliary machinery

The exact motor-control requirements depend on the mechanical process and torque profile.

10.7 Industrial HVAC

Large industrial buildings and facilities can have ventilation and cooling systems requiring very high motor power.

Variable-speed operation allows airflow to be adjusted to actual demand.

This can improve process control and potentially reduce energy consumption compared with constant-speed operation.

11. Product Advantages

11.1 Very High Power Capacity

The main advantage is the combination of 960 A current capacity and 900 kW Normal Duty power.

This allows the drive to control very large industrial motors.

It is appropriate where smaller VFDs cannot provide sufficient output current.

11.2 Variable-Speed Operation

A motor does not always need to operate at maximum speed.

The drive can adjust the motor speed according to process demand.

This is especially useful for pumps and fans.

11.3 Potential Energy Savings

For variable-torque loads, reducing motor speed can significantly reduce power consumption.

This can make a large variable-frequency drive attractive for pumps and fans that spend considerable time below full capacity.

Actual energy savings depend on the load curve, operating hours, motor efficiency and process requirements.

11.4 Controlled Acceleration

Large motors can impose substantial mechanical stress during startup.

Controlled acceleration allows the motor to reach operating speed gradually.

This can reduce mechanical shock and improve equipment life.

11.5 Controlled Deceleration

The drive can also control the motor during stopping.

However, this particular configuration does not include an internal dynamic-braking transistor.

Applications that require frequent rapid deceleration should therefore be evaluated for an appropriate external braking or regenerative solution.

11.6 Industrial Network Integration

Embedded EtherNet/IP allows the drive to communicate with an automation controller.

This makes it possible to exchange:

• Start commands
• Stop commands
• Speed references
• Actual speed
• Output current
• Frequency
• Status
• Warnings
• Fault information
• Process values

11.7 PID Process Control

The drive can be used in closed-loop process applications.

For example, a pump may be required to maintain a pressure setpoint.

The drive can adjust motor speed based on the difference between the desired pressure and the actual pressure.

The same principle can be applied to flow, airflow and other process variables.

11.8 Industrial Protection

The IP54 / Type 12 configuration provides a practical enclosure arrangement for industrial environments.

It reduces the need to place the drive inside a separate basic protective enclosure in applications where the existing industrial environment is suitable for the specified enclosure rating.

12. Automation Architecture

A typical installation can be represented as:

Incoming 690 VAC Supply

↓

Protection and Switching Equipment

↓

PowerFlex 755 Drive

↓

↓

Pump / Fan / Conveyor / Process Equipment

At the automation level:

PLC / Controller

↓

EtherNet/IP

↓

PowerFlex 755

↓

Motor Control

↓

Mechanical Process

The drive therefore serves two roles.

First, it is the power-electronic device that controls the motor.

Second, it is a networked automation component that exchanges operating information with the control system.

13. Communication Functions

The integrated network capability can provide useful information for both operation and maintenance.

Data	Purpose
Start command	Starts motor operation
Stop command	Stops motor operation
Speed reference	Sets target speed
Actual speed	Provides motor speed feedback
Output frequency	Indicates drive operating frequency
Output current	Indicates motor loading
Drive status	Indicates running / stopped / fault state
Warning	Identifies abnormal condition
Fault	Identifies a trip condition
Process reference	Provides process setpoint
PID feedback	Provides closed-loop process information

14. PID Applications

PID control can be particularly valuable for large pumps and fans.

For a pressure-control system, the drive can continuously compare:

Pressure Setpoint

against

Actual Pressure

and then adjust motor speed.

For a ventilation system, a similar method can be used for airflow.

For a water system, the process variable could be flow or pressure.

This eliminates the need to operate the motor at a fixed speed regardless of the actual process requirement.

15. Cooling System

The 20G11JF960JN0NNNNN uses forced-air cooling.

The cooling fan is a backward-curved centrifugal type.

The approximate airflow is:

1,805 m³/h

The approximate electrical input of the cooling fan is:

0.45 kW

These values demonstrate that the cooling system itself is an important part of the installation.

The electrical room or cabinet should provide an appropriate airflow path.

Hot exhaust air should not be allowed to recirculate directly into the drive’s cooling inlet.

16. Environmental Parameters

Parameter	Typical Specification
Operating Temperature	Approximately -20°C to +60°C class
Storage Temperature	Approximately -40°C to +70°C
Enclosure	IP54 / Type 12
Humidity	Industrial, non-condensing conditions
Cooling	Forced Air
Installation	Industrial electrical environment
Altitude	Application-dependent; derating may apply
Dust	Must remain within enclosure/environmental limits
Corrosive Atmosphere	Requires separate evaluation
Direct Water Exposure	Not recommended without appropriate environmental assessment

17. Dynamic Braking Considerations

The catalog configuration 20G11JF960JN0NNNNN has no internal dynamic-braking transistor.

This is an important point when selecting the drive.

During deceleration, a motor can return energy to the DC bus.

If the application requires rapid deceleration, this energy must be handled appropriately.

Potential solutions can include:

• External braking equipment
• Regenerative drive systems
• Longer deceleration time
• Mechanical braking
• Application-specific energy-management equipment

The correct solution depends on the inertia, stopping time, motor power and operating cycle.

Applications such as large conveyors, high-inertia rotating machinery and rapid-cycle equipment should therefore receive a dedicated braking analysis.

18. Mechanical Installation

This is a very large packaged drive.

The 800 mm deep MCC-style construction is a major mechanical characteristic.

A listed mechanical dimension is approximately 78.35 inches, or about 1,990 mm, for the relevant cabinet dimension.

The complete installed dimensions can vary according to the exact package configuration.

A practical engineering table is therefore:

Mechanical Item	Approximate Value
Frame	9
Enclosure	IP54 / Type 12
MCC Style	Yes
Nominal enclosure depth class	800 mm
Listed dimensional reference	Approx. 1,990 mm
Width	Configuration-dependent
Height	Configuration-dependent
Weight	Approx. 1,246 kg
Cooling	Forced air
Installation	Floor-mounted industrial package

The 1,246 kg weight is especially important.

This is not equipment that should be handled as a normal wall-mounted VFD.

Transportation and installation may require:

• Suitable lifting equipment
• Reinforced floor support
• Adequate access doors
• Transportation route planning
• Cabinet positioning
• Maintenance clearance
• Removal clearance
• Safe power-cable routing

19. Electrical Installation Considerations

Before installation, the following should be evaluated:

Item	Importance
690 VAC supply	Critical
Three-phase supply	Critical
Motor rated voltage	Critical
Motor full-load current	Critical
Normal / Heavy Duty classification	Critical
Short-circuit current	Critical
Upstream protection	Critical
Grounding	Critical
Motor cable size	Critical
Motor cable length	High
EMC requirements	High
Cooling airflow	Critical
Ambient temperature	High
Braking requirements	High
Network configuration	High
Mechanical clearance	Critical
Floor loading	Critical
Maintenance access	High

20. Recommended Same-Series Models

The following five models are useful alternatives or related configurations within the PowerFlex 755 family.

The selection should be based on motor current, voltage, power and duty cycle rather than simply selecting the closest numerical model.

Model	Voltage	Current	Normal Duty	Heavy Duty	Frame	Enclosure	Dimensions	Weight (kg)
20G11JF650JN0NNNNN	690 VAC	650 A	710 kW	500 kW	9	IP54 / Type 12	800 mm MCC-style class	Configuration-dependent
20G11JF710JN0NNNNN	690 VAC	710 A	800 kW	590 kW	9	IP54 / Type 12	800 mm MCC-style class	Configuration-dependent
20G11JF765JN0NNNNN	690 VAC	765 A	750 kW	630 kW	9	IP54 / Type 12	800 mm MCC-style class	Configuration-dependent
20G11JF795JN0NNNNN	690 VAC	795 A	800 kW	710 kW	9	IP54 / Type 12	800 mm MCC-style class	Approx. 1,200 kg class*
20G11JF960JN0NNNNN	690 VAC	960 A	900 kW	800 kW	9	IP54 / Type 12	800 mm MCC-style class	Approx. 1,246

* Actual weight depends on the complete packaged configuration.

21. Same-Series Model Comparison

Model	Current	Normal Duty	Heavy Duty	Main Advantage
20G11JF650JN0NNNNN	650 A	710 kW	500 kW	Lower-capacity option
20G11JF710JN0NNNNN	710 A	800 kW	590 kW	Suitable for large but lower-current motors
20G11JF765JN0NNNNN	765 A	750 kW	630 kW	Closely related high-power configuration
20G11JF795JN0NNNNN	795 A	800 kW	710 kW	Higher-current alternative
20G11JF960JN0NNNNN	960 A	900 kW	800 kW	Target high-capacity configuration

The 20G11JF795JN0NNNNN is particularly close to the target model and can be considered where approximately 795 A is sufficient.

The 20G11JF960JN0NNNNN provides a higher current capacity and is appropriate when the motor current or application requirements exceed the lower configurations.

The lower-current models can reduce the amount of unused drive capacity when the motor does not require 960 A.

29. Why Choose the 20G11JF960JN0NNNNN?

There are several reasons to choose this model rather than a lower-current PowerFlex 755.

First, the 960 A current rating provides additional electrical capacity.

Second, the 900 kW Normal Duty rating gives it a larger operating range than the 795 A model.

Third, the 800 kW Heavy Duty rating makes it suitable for very large demanding loads.

Fourth, the 690 VAC architecture is appropriate for high-power industrial motor systems.

Fifth, the IP54 / Type 12 packaged enclosure is well suited to many industrial electrical environments.

Finally, the drive can be integrated into an automation system through EtherNet/IP.

30. When the 20G11JF795JN0NNNNN May Be Better

The larger 960 A drive is not always the best choice.

If the motor only requires approximately 700–800 A, selecting a smaller drive may be more economical and may reduce unused capacity.

For example, the 20G11JF795JN0NNNNN may be a more appropriate choice when the motor current is comfortably within the 795 A range and the application does not require the additional capacity of the 960 A model.

The same principle applies to the 765 A, 710 A and 650 A configurations.

Drive sizing should be based on the actual motor current and load profile.

33. Important Limitations

The high capacity of the 20G11JF960JN0NNNNN also creates several practical considerations.

The physical size is large.

The approximate 1,246 kg weight means that normal manual handling is impossible.

The 690 VAC supply requires appropriate high-voltage electrical engineering.

The forced-air cooling system requires sufficient ventilation.

The absence of an internal dynamic-braking transistor means that high-inertia applications requiring rapid stopping require additional analysis.

The lack of a local HIM means that the local operator interface must be considered separately if required.

The drive is therefore best suited to a properly engineered industrial installation rather than a simple machine-panel retrofit.

34. Maintenance Considerations

A high-power drive requires regular attention to thermal and electrical conditions.

Important maintenance points include:

• Cooling fans
• Air passages
• Electrical terminals
• Grounding connections
• Power connections
• Control wiring
• Network connections
• Environmental contamination
• Fault history
• Warning history
• Operating temperature
• Motor cable condition
• Cabinet ventilation

The cooling fans are particularly important.

Fan degradation can reduce airflow and increase internal temperature.

Dust accumulation can also reduce cooling performance.

Regular inspection can help identify cooling and electrical problems before they become serious equipment failures.

40. Conclusion

The 20G11JF960JN0NNNNN is a high-capacity Allen-Bradley PowerFlex 755 AC drive designed for large industrial motor applications.

Its key electrical characteristics are 690 VAC, three-phase input, 960 A output current, 900 kW Normal Duty and 800 kW Heavy Duty.

The drive is built in a Frame 9, IP54 / Type 12, 800 mm deep MCC-style package and uses forced-air cooling.

The combination of high current capacity, high power rating, industrial enclosure protection, process-control functions and EtherNet/IP communication makes it particularly suitable for large pumps, fans, conveyors, mining systems, material-handling equipment and large process machinery.

For pumping and fan applications, variable-speed operation can provide more precise process control and may reduce energy consumption when the process does not require maximum motor output.

For conveyor applications, controlled acceleration can reduce mechanical shock and improve the starting behavior of high-inertia equipment.

For automated production systems, the embedded EtherNet/IP capability allows the drive to exchange commands, operating values, warnings and fault information with the control system.

The main points requiring special attention are the 960 A current rating, 900 kW Normal Duty rating, 800 kW Heavy Duty rating, approximately 1,246 kg reference weight, large Frame 9 mechanical construction, cooling requirements and lack of an internal dynamic-braking transistor.

Compared with the 20G11JF795JN0NNNNN, this model provides a higher 960 A current rating and a higher 900 kW Normal Duty capacity.

Compared with the 20G11JF765JN0NNNNN, it provides substantially greater current and power capability.

The 20G11JF650JN0NNNNN, 20G11JF710JN0NNNNN, 20G11JF765JN0NNNNN and 20G11JF795JN0NNNNN are useful lower-capacity related configurations within the same PowerFlex 755 family.

For smaller industrial equipment, models such as the 25B-D017N114, 20F11NC043JA0NNNNN, 20GE1ND027JA0NNNNN and 20GE1ND096JA0NNNNN provide more appropriately sized solutions.

For a high-power 690 VAC installation, however, the 20G11JF960JN0NNNNN is best understood as a 900 kW-class industrial motor-control system rather than simply a conventional VFD.

The correct selection should always begin with the motor’s voltage and full-load current, followed by the load profile, duty classification, acceleration and deceleration requirements, braking requirements, environmental conditions, cooling, communication requirements and mechanical installation.

In practical terms, the model can be summarized as:

960 A + 690 VAC + 900 kW Normal Duty + 800 kW Heavy Duty + Frame 9 + IP54 / Type 12 + Forced Air + EtherNet/IP + High-Power Industrial Motor Control.
