Connecting the power cables
Connection diagram
Notes:
• If shielded supply (input) cable is used, and the conductivity of the shield is not sufficient (see section Motor
cable shield on page 52), 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 Motor cable shield on page 52) and the cable has no symmetrical ground conductors.
