operated with insufficient grounding, then the protection and monitoring functions can fail.
Death, serious injury, or material damage will result.

● Follow these steps when grounding the machine:
– Establish the connections in a cabinet.
– Ensure that the connections are also established over several cabinets.
– Establish the ground connection for the whole plant immediately.

jumper is supplied with each cabinet. To screw several cabinets together, proceed as follows:
