DANGER
Danger due to failure of the protective and monitoring equipment
The converter must be grounded to ensure that it operates safely and reliably. If the converter
is operated with insufficient grounding, then the protection and monitoring functions can fail.
Death, serious injury, or material damage will result.
● Always apply all of the necessary protective measures.
● Always observe the five safety rules when working with the converter.
● 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.
If several cabinets are set up as one unit, the grounding connections of the individual cabinets
must be connected with each other. A grounding lug connection cable is supplied with each
cabinet. To connect the ground connections for several cabinets, proceed as follows:
1. Insert the grounding cable
①
through the side panel of the cabinet.
