Grounding connections
The grounding points on the frame of the electric machine are for safety grounding, and signal cables and power cable
shields have their own grounding points.
For proper and safe operation, it is important to ensure proper grounding (earthing) of the
machine and cable shields connected to the machine. The electric machine has a connection point
for machine enclosure grounding and for low voltage cable shield grounding.
