Shaft grounding is recommended (NEMA MG1 31.4.4.3) as an effective means of bearing protection
for motors operated from inverter power. One grounding device is adequate to bleed down inverter-
sourced shaft voltages, thereby protecting both bearings for motors as large as 6085 frame. Kits includes
grounding ring, mounting hardware and instructions. Shaft ground rings fit these NEMA shaft extension
frames listed below, they are designed to mount on the shaft end.
