Connecting ground

Insufficient grounding
The drive must be grounded to ensure that it operates safely and reliably. If the drive is
operated with insufficient grounding, then the protection and monitoring functions can fail.
Death, serious injury, or material damage will result.
To ensure the correct functioning of the protection and monitoring equipment, ground the
device.
Each cabinet has a grounding lug for grounding the components installed in the cabinet. It is
located at the bottom of the cabinet. Connect the cabinets securely to the plant grounding
system via these grounding lugs.
