The 2453 × 600 × 800 mm and approximately 623 kg figures should be treated as a Frame 8 MCC-style cabinet reference rather than a universal shipping weight for every possible installation arrangement. The actual assembled equipment dimensions and weight can vary with enclosure, options, disconnect equipment, cabinet arrangement, cable-entry configuration, and other selected components. 

---

4. Electrical Rating

The central electrical rating of the 20G1ALC567JN0NNNNN is 567 A at 400 VAC, three phase.

This places the drive in the high-current end of the PowerFlex 755 range.

The model provides different motor-power capabilities according to application duty.

Duty Classification	Current / Power Capability
Light Duty	Approximately 567 A class / 355 kW
Normal Duty	567 A / 315 kW
Heavy Duty	Approximately 472 A / 250 kW
Input Voltage	400 VAC
Input Phase	Three Phase
Frame	8

The distinction between light duty, normal duty, and heavy duty is important when selecting the drive.

A motor application with relatively stable loading may be evaluated using the normal-duty rating, while applications with greater overload requirements, high starting torque, or demanding acceleration characteristics may need to be evaluated against the heavy-duty rating.

The correct selection should always be based on the motor nameplate current, actual load profile, acceleration requirements, overload requirements, ambient conditions, and application duty rather than simply comparing motor horsepower or kilowatt values.

---

5. Normal-Duty Rating

The normal-duty rating is one of the most important specifications of this model.

The drive is rated at approximately:

567 A / 315 kW normal duty at 400 VAC.

This makes it suitable for large motors used in industrial process equipment, material handling, large pumping systems, fans, blowers, compressors, and similar machinery.

For a 315 kW-class application, the motor’s actual full-load current should still be checked carefully.

The drive should not be selected solely because the motor is labeled as a 315 kW motor.

Motor efficiency, power factor, supply voltage, motor design, operating temperature, altitude, overload requirements, and actual mechanical load can all influence the required drive rating.

---

6. Heavy-Duty Rating

The heavy-duty capability is approximately:

472 A / 250 kW class.

Heavy-duty selection is especially relevant for machinery with high starting torque, frequent acceleration, significant load variation, or short-duration overload requirements.

Typical examples include:

• Heavy conveyors
• Crushers
• Material-handling machinery
• Large mixers
• High-inertia machinery
• Industrial rollers
• Process equipment
• Machinery requiring repeated acceleration

The heavy-duty rating should be compared against the actual motor current and overload profile.

For demanding mechanical loads, current is generally more useful than motor kW alone when determining whether the drive has sufficient capacity.

---

7. Light-Duty Capability

The light-duty power capability is approximately 355 kW.

Light-duty applications generally have less severe overload requirements and may permit a higher motor power rating from the same drive hardware.

This capability is useful for applications such as large fans, certain centrifugal pumps, blowers, and other variable-torque equipment where the motor load profile is relatively predictable.

Variable-torque applications can often benefit from the higher power utilization available under the appropriate duty classification.

---

8. PowerFlex 755 Series Characteristics

The PowerFlex 755 series is intended for industrial applications requiring more than basic speed control.

The series is designed for applications involving:

• Variable-speed motor operation
• Industrial automation
• Networked drive control
• Process control
• Pump and fan control
• Conveyor control
• Large machinery
• Production equipment
• Material handling
• Motor protection
• Acceleration and deceleration management
• Speed regulation
• Torque control
• Process integration

The 755 architecture also allows the drive to be integrated into larger automation systems where drive status, commands, diagnostic information, and operating parameters need to be exchanged with a control system.

---

9. Embedded EtherNet/IP

One of the important features of the 20G1ALC567JN0NNNNN is its embedded EtherNet/IP communication capability.

This makes the drive suitable for networked industrial automation systems where the drive needs to communicate with a controller or supervisory system.

Typical network functions can include:

• Start and stop commands
• Speed reference
• Frequency reference
• Drive status
• Fault status
• Alarm information
• Output current monitoring
• Motor speed monitoring
• Drive parameter access
• Diagnostic information
• Remote configuration
• Process control information

EtherNet/IP connectivity can significantly reduce the amount of traditional hardwired control wiring required for many applications.

It also allows drive information to become part of the broader automation architecture.

---

10. No HIM Configuration

The catalog configuration 20G1ALC567JN0NNNNN is supplied with a blank / no HIM configuration.

HIM means Human Interface Module.

A no-HIM configuration is useful when the drive is intended to be operated and configured primarily through:

• PLC control
• EtherNet/IP
• External control stations
• Engineering software
• Remote operator interfaces
• Centralized automation systems

This configuration can be attractive for large industrial systems where individual drives are installed inside electrical rooms or cabinets and operators do not need a local keypad on every drive.

A remote operator station can instead provide centralized access to drive commands, operating values, alarms, and diagnostic information.

---

11. AC Input with Precharge

The drive uses an AC input with precharge configuration.

The precharge function is important in high-power drive systems because the DC bus capacitors represent a significant electrical energy-storage system.

Controlled charging of the DC bus reduces the electrical stress that could otherwise occur when a large drive is connected directly to the incoming power supply.

For a Frame 8 high-power drive, correct installation of the input power system, disconnect equipment, protective devices, grounding system, and cabling is especially important.

---

12. No DC Terminals

This particular configuration is specified with no DC terminals.

This means the drive is primarily intended to receive its input through its AC input arrangement rather than being selected as a configuration for external DC-bus connections.

This distinction is important when designing multi-drive DC-bus systems or applications involving regenerative energy.

If an application requires a common DC bus, shared DC bus architecture, regenerative braking, or other specialized energy-management functions, the exact drive configuration must be evaluated before selection.

---

13. Filtered Configuration

The 20G1ALC567JN0NNNNN uses a filtered configuration.

Input filtering can help manage electrical noise and electromagnetic interference associated with high-power switching equipment.

However, filtering should not be treated as a substitute for proper installation practices.

Good installation practice should also include:

• Correct grounding
• Appropriate cable selection
• Proper shield termination
• Separation of power and signal wiring
• Correct motor cable routing
• Proper cabinet bonding
• Correct control-cable routing
• Appropriate installation of communication cables

Large Frame 8 drives can generate significant electrical noise if installed incorrectly, particularly when long motor cables and multiple variable-speed drives are installed in the same facility.

---

14. CM Jumper Installed

The J configuration of this model includes the common-mode capacitor jumper installed.

This is an important difference between J-configured and A-configured versions of similar PowerFlex 755 catalog numbers.

The common-mode capacitor arrangement affects the electrical relationship between the drive and the grounding system.

Therefore, the jumper configuration should be considered as part of the overall electrical-system design.

It should not be changed simply because another catalog number has a different jumper configuration.

The correct configuration depends on the grounding system, power distribution architecture, EMC requirements, and installation instructions applicable to the equipment.

---

15. Dynamic Braking

The 20G1ALC567JN0NNNNN is specified with no internal dynamic-braking transistor.

This does not mean that the drive cannot decelerate a motor.

It means the drive does not have an internal dynamic-braking transistor configured for dissipating regenerative energy through an external braking resistor arrangement.

This distinction becomes important for high-inertia machinery.

When a large motor decelerates, the mechanical energy stored in the rotating system can flow back toward the drive’s DC bus.

If the regenerative energy is sufficiently large, the DC-bus voltage can increase.

Applications that require rapid deceleration should therefore be evaluated carefully.

Examples include:

• Large conveyors
• Centrifuges
• Rollers
• Flywheel machinery
• High-inertia fans
• Large mixers
• Hoisting-related machinery
• Rapid-stop production equipment

For these applications, the braking strategy should be considered during the original drive selection.

---

16. Frame 8 Construction

The 20G1ALC567JN0NNNNN uses Frame 8 construction.

Frame 8 is intended for large industrial drive systems and is physically much larger than compact PowerFlex drives.

The mechanical installation therefore requires more planning.

Important considerations include:

• Floor loading
• Cabinet anchoring
• Lifting equipment
• Maintenance access
• Cooling airflow
• Cable bending radius
• Power cable entry
• Control cable entry
• Network cable routing
• Electrical clearance
• Door clearance
• Heat dissipation
• Service access
• Replacement access

For large industrial installations, the drive should be considered as part of the overall electrical room or MCC arrangement rather than as a small standalone VFD.

---

17. Dimensions and Weight

The physical size is an important part of the selection process.

A typical Frame 8 MCC-style IP20 arrangement is approximately:

Mechanical Parameter	Approximate Value
Frame	8
Height	2453 mm
Width	600 mm
Depth	800 mm
Approximate Weight	623 kg
Installation	Floor mounted
Cabinet Style	MCC style
Protection	IP20 / Type 1

These values should be regarded as engineering reference dimensions for the large Frame 8 cabinet arrangement.

The final physical dimensions can vary depending on the selected enclosure configuration, options, power distribution equipment, disconnect devices, cabinet layout, and other accessories.

For transportation planning, lifting arrangements should be confirmed using the final equipment drawing.

A Frame 8 system weighing several hundred kilograms should not be handled using the same procedures used for compact VFD products.

---

18. Cooling System

The drive uses air cooling / forced-air cooling.

High-power drives generate significant heat during operation.

The cooling system must therefore be considered during cabinet design.

The installation should provide adequate airflow and should prevent hot exhaust air from being drawn back into the drive intake.

Typical considerations include:

• Cabinet ventilation
• Airflow direction
• Ambient temperature
• Filter maintenance
• Fan condition
• Cabinet heat load
• Room ventilation
• Clearance around air intake and exhaust
• Accumulation of dust

Poor ventilation can increase drive temperature and reduce operating reliability.

For continuous industrial operation, cooling should be treated as part of the complete system design rather than as an accessory issue.

---

19. Operating Environment

The commonly specified operating-temperature range for this configuration is approximately -20 to 60 °C, while the storage range is approximately -40 to 70 °C. 

The actual usable rating at elevated ambient temperatures can depend on the installation conditions and applicable derating requirements.

Environmental factors that should be evaluated include:

• Ambient temperature
• Altitude
• Humidity
• Dust
• Corrosive gases
• Vibration
• Electrical noise
• Cooling-air quality
• Cabinet ventilation
• Motor cable length

For installations in harsh environments, the IP20 drive should normally be installed inside an appropriately protected enclosure.

---

20. Main Product Advantages

The 567 A current rating allows the drive to control large industrial motors that would be outside the practical range of compact VFD families.

This makes the model particularly useful for centralized industrial drive systems.

---

20.2 High Power Capability

With approximately 355 kW light-duty capability and 315 kW normal-duty capability, the drive is suitable for large motor-driven machinery.

It can therefore be used in applications where a compact VFD would not have sufficient current capacity.

---

The drive can be evaluated for light-duty, normal-duty, and heavy-duty applications.

This provides greater flexibility when matching the drive to different motor-load characteristics.

---

20.7 No Local HIM Required

The no-HIM configuration can be advantageous in centralized automation systems.

It allows the equipment designer to use PLCs, HMIs, engineering software, and network control rather than installing a local keypad on every drive.

---

20.8 Filtered Configuration

The filtered configuration can help with electromagnetic compatibility requirements when combined with appropriate installation practices.

This is especially useful in industrial environments containing multiple drives, PLCs, sensors, communication networks, and other electronic equipment.

---

Large water and wastewater facilities use many high-power motors.

Potential applications include:

• Large pumps
• Lift stations
• Aeration equipment
• Blowers
• Water circulation

34. Difference Between the Target Model and Related JN0/JN2/JN4 Versions

The first part of the catalog number identifies the electrical and mechanical platform, while later characters define important configuration differences.

For the 567 A, 400 VAC, Frame 8 family, the following configurations are particularly useful to compare:

Model	Current	Power Class	CM Jumper	HIM Configuration	Main Difference
20G1ALC567JN0NNNNN	567 A	355/315/250 kW	Installed	No HIM	Basic no-HIM configuration
20G1ALC567JN2NNNNN	567 A	355/315/250 kW	Installed	Local/Handheld HIM	Local operator access
20G1ALC567JN4NNNNN	567 A	355/315/250 kW	Installed	Enhanced LCD / Full Numeric HIM	Advanced local display
20G1ALC567AN0NNNNN	567 A	355/315/250 kW	Removed	No HIM	Different CM jumper configuration

The target 20G1ALC567JN0NNNNN is therefore particularly suitable when the application does not require a local HIM and the electrical system calls for the J configuration with the common-mode capacitor jumper installed.

• Floor loading
• Lifting equipment
• Service clearance
• Door clearance
• Cable bending radius

Thermal Requirements

• Heat dissipation
• Cabinet ventilation
• Ambient temperature
• Airflow
• Fan maintenance

Control Requirements

39. Overall Technical Assessment

The Allen-Bradley 20G1ALC567JN0NNNNN is a high-capacity industrial AC drive designed for large three-phase motor applications.

Its 567 A current rating, 400 VAC three-phase supply, 315 kW normal-duty rating, 250 kW heavy-duty rating, and Frame 8 construction place it firmly in the large industrial drive category.

The embedded EtherNet/IP capability makes the drive suitable for modern networked control systems, while the no-HIM configuration is particularly appropriate for installations where operation and monitoring are performed through a PLC, HMI, SCADA system, or engineering workstation.

The filtered input configuration and installed CM jumper provide an important electrical configuration for applications where EMC and grounding considerations form part of the drive-system design.

The absence of an internal dynamic-braking transistor should be considered carefully for high-inertia loads and applications requiring rapid deceleration.

From a mechanical standpoint, this is not a compact VFD. The Frame 8 architecture requires proper floor support, lifting arrangements, ventilation, cable access, maintenance space, and electrical-room planning.

41. Conclusion

The Allen-Bradley 20G1ALC567JN0NNNNN PowerFlex 755 is best regarded as a large-frame industrial variable-frequency drive for demanding motor-control applications.

Its combination of 567 A current capability, 400 VAC three-phase operation, 315 kW normal-duty power, 250 kW heavy-duty capability, Frame 8 construction, forced-air cooling, IP20 protection, filtered input, installed CM jumper, embedded EtherNet/IP, and no-HIM configuration makes it particularly suitable for large automated industrial systems.

For applications requiring a slightly lower current rating, the 20G1ALC540JN0NNNNN is a logical alternative.

For the same current and power rating with local operator access, the 20G1ALC567JN2NNNNN or 20G1ALC567JN4NNNNN can be considered.

For higher-power applications, the 20G1ALC650JN0NNNNN and 20G1ALC750JN0NNNNN provide progressively greater current and power capacity.

The most important point when selecting among these models is to match the drive to the actual motor full-load current and load duty. Motor kW alone should not be used as the only selection criterion.

For large pumps, fans, blowers, conveyors, compressors, mixers, water-treatment systems, process equipment, mining machinery, and other large industrial machines, the 20G1ALC567JN0NNNNN provides a strong combination of high-current capability, industrial networking, flexible motor control, and large-frame installation capability.

For a complete project, the final selection should additionally confirm motor nameplate data, duty cycle, overload requirements, braking requirements, ambient conditions, altitude, motor cable length, grounding arrangement, cabinet ventilation, short-circuit requirements, and the required control architecture.
