Ground Fault

What does E.GF mean?

The inverter output is shut off if an earth (ground) fault overcurrent flows on the inverter's output side (motor/load side). This protective shutdown prevents electrical hazards, motor damage, and further system failures due to insulation breakdown.

• Ground Fault detected.
• Current leakage to ground from a phase.
• Insulation failure in motor windings or cabling.
• Faulty wiring causing a path to ground.
• Detection of earth fault current.

1. 1

   Check the motor and its connection cable for any signs of a ground fault, such as damaged insulation.

2. 2

   Identify and remedy the specific portion of the system where the earth (ground) fault has occurred.
