Issue:
Using GFI (Ground fault interrupt) on a ATV11.
Product Line:
ATV11
Environment:
All
Cause:
Feeding the ATV11 with GFI
Resolution:
The PWM in the drive can cause problems with the GFI, because of the capacitance to ground. It is not recommend to use a GFI with the drive.
If a GFI have to be used, then suggest installing an isolation transformer between the GFI and the drive. Also the motor needs to be properly grounded.
