Always disconnect power before installation and wiring. Ensure proper grounding of both the drive and the motor. Verify all connections are secure and that the drive is installed in an environment with adequate ventilation and within the specified temperature range to prevent overheating.

8. What do common fault codes like "OC" and "OH" indicate on the GD200A-5R5G/7R5P-4?

"OC" typically signifies an overcurrent fault, meaning the motor or drive is drawing more current than its rated limit. "OH" indicates an overheat fault, suggesting the drive's internal temperature has exceeded safe operating limits. Both require investigation into the cause, such as motor load or ventilation issues.

9. Does the INVT GD200A-5R5G/7R5P-4 include a braking unit?

Yes, models up to 7.5 kW (including the GD200A-5R5G/7R5P-4) feature a built-in braking unit. This allows for dynamic braking through an external resistor, enabling faster deceleration and holding loads in position when necessary. This simplifies installation for many applications.
