Notes:
• If shielded supply (input) cable is used, and the conductivity of the shield is not sufficient (see section
Selecting the power cables on page 43 ), use a cable with a ground conductor (1) or a separate PE cable
(2).
• For motor cabling, use a separate ground cable (3) if the conductivity of the cable shield is not sufficient
(see section Selecting the power cables on page 43 ) and the cable has no symmetrical ground conductors.
