Use a separate grounding PE cable (2a) or a cable with a separate PE conductor (2b) if the
conductivity of the shield does not meet the requirements for the PE conductor. See section
Selecting the power cables (page 69).

360-degree grounding is recommended if shielded cable is used. Ground the other end of
the input cable shield or PE conductor at the distribution board.

360-degree grounding is required.4

Use a separate grounding cable if the shield does not meet the requirements of IEC 61800-
5-1 and there is no symmetrically constructed grounding conductor in the cable. See section
Selecting the power cables (page 69).

du/dt filter or sine filter (optional, see Filters (page 295)).

Note: If there is a symmetrically constructed grounding conductor on the motor cable in addition
to the conductive shield, connect the grounding conductor to the grounding terminal at the drive
and motor ends.
Do not use an asymmetrically constructed motor cable for motors above 30 kW. Connecting its
fourth conductor at the motor end increases bearing currents and causes extra wear.
