You can use a maximum of three parallel cables. 1
The diagram shows the grounding connections of an enclosed filter: It includes the grounding
clamps for the cable shields (PE conductors). If you have an enclosed (IP22) filter, you do the con-
nection as shown above. If you have a non-enclosed (IP00) filter, you must connect the cable shields
to the PE busbar of the cabinet in which you have installed the filter. You must also make sure that
the filter frame has a proper connection to the cabinet PE busbar through the mounting screws
and cabinet metal structures. If in doubt, use a separate grounding wire. 2
