Can a GV2/GV3 device be used on the output of a drive?

Issue:
GV2 as isolation or overload on the motor.

Product Line:
Altivar drives, Tesys GV manual starters

Environment:
All

Cause:
Installation or Multimotor

Resolution:
It is not recommended to use GV2's because the range frequency is only for 50/60Hz and it does not function well with the PWM output from a drive.  The GV2 may nuisance trip and/or overheat.

When the application is done with multi motors in parallel Schneider recommends a thermal relay such as TeSys LRD or LR3D (Class 10).
The TeSys LRD or LR3D work on the range frequency 0 to 400Hz.
