The 2GU41007 is a 7.5 HP (5.5 kW) three-phase AC variable frequency drive from Reliance Electric GP-2000 series. It uses 460 VAC input and is designed for general industrial motor speed control. It is commonly used for fans, pumps, conveyors and other standard industrial equipment. This model has been discontinued, and refurbished units are mainly used for maintenance and part replacement of legacy systems.

2 stands for the standard industrial drive series. GU represents the 460 VAC voltage platform of GP-2000 series. 41007 means 460 VAC input, 7.5 HP rated power and hardware revision 07.

Motor power is 7.5 HP (5.5 kW) with apparent power of 8.8 kVA. Input voltage is 460 VAC ±10%, three-phase, 50/60 Hz. Output voltage ranges from 0 to 460 VAC, three-phase. Output frequency ranges from 0 to 400 Hz. The continuous rated output current is 11 A. It adopts open-loop V/F control mode. Built-in protection functions include overcurrent, overvoltage, undervoltage, overtemperature, short-circuit and ground fault protection. It is equipped with NEMA 1 enclosure. The operating temperature ranges from 0 °C to +45 °C. The dimensions are 394 × 203 × 248 mm in height, width and depth. The overall weight is approximately 9.9 kg.

It is equipped with power terminals for three-phase main input, motor output and DC bus braking connection. The control terminals support ±10 V analog input for speed reference and 24 VDC digital I/O for start stop, fault reset and jog functions. It applies Reliance proprietary protocol and has no standard fieldbus ports. The onboard keypad and 7-segment display are used for parameter setting and fault code checking. This model has no encoder interface and only supports open-loop V/F control.

It provides stable speed regulation for 7.5 HP three-phase AC motors with V/F control. It effectively saves energy for variable-torque loads like fans and pumps. It supports external braking resistors to realize rapid deceleration. Real-time system monitoring and fault code recording help users locate and solve problems quickly. Operators can configure acceleration time, deceleration time, current limit and I/O logic via the local panel.

It is applicable to conveyors, packaging machines and assembly lines in light manufacturing. It matches medium-sized fans, pumps and agitators in HVAC and process industries. It works for conveying and lifting equipment driven by 7.5 HP AC motors. It serves as a direct replacement for old GP-2000 series drives in legacy automation systems.

Install the drive in a well-ventilated cabinet and keep at least 50 mm clearance around the unit for heat dissipation. Use shielded cables for power and control wiring, and tighten all terminals securely. Verify the input voltage before powering on. Energize the control circuit first and then the main power, and set parameters according to the motor nameplate. Inspect wiring connections every quarter and clean internal dust regularly. Disconnect all power and wait 5 minutes for DC bus capacitors to fully discharge before any inspection or maintenance work.
