An earth ground fault has resulted in a discharge from the
output phases to ground, either in the cable between the
adjustable frequency drive and the motor or in the motor
itself. Further fan operation is not recommended until

The Latching behavior for this diagnostic is latched in the
drive. When the drive diagnostics are reset this
diagnostic will be cleared in the Symbio 800 controller.
This drive alarm may be Trip Locked at the TR150 drive.
If the drive determines that the condition could cause
damage to the drive, the drive protects itself by
generating a Trip Lock that can only be cleared by cycling
power.
