Use a separate grounding PE cable (2a) or a cable with a separate grounding conductor (2b) if the
conductivity of the shield does not meet the requirements for the PE conductor. See section Gen-
eral guidelines (page 82).

ABB recommends 360-degree grounding at the cabinet entry if a shielded cable is used. Ground
the other end of the input cable shield or PE conductor at the distribution board.

ABB recommends 360-degree grounding at the cabinet entry.4
Use a separate grounding cable, if the conductivity of the shield does not meet the requirements
of IEC 61800-5-1 (see section General guidelines (page 82)) and there is no symmetrically constructed
grounding conductor in the cable.
5
If there is a symmetrically constructed grounding conductor in 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. Connecting its fourth conductor at the
motor end increases bearing currents and causes extra wear.
