Is a High Leg input to a VFD ok?

High leg delta power sources (also called stinger leg, wild leg, center grounded delta) can be wired directly to the VFDs input terminals without issue. No derate is required. This is due to the fact that the input of the VFD does not reference to ground. 


Important items to note
  1. Ensure phase to phase voltage is balanced and within specification
  2. Disable the internal EMC filter if present. See VFD manual for instructions.
