Notes:
– If shielded supply (input) cable is used, and the conductivity of the shield is less than 50% of the conduc-
tivity of a phase conductor, 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 less than 50%
of the conductivity of a phase conductor and the cable has no symmetrical ground conductors. See also
section Selecting the power cables on page 41.

The UDC+/UDC– connectors can be used for
common DC configurations. See page 56.
