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 AC power cables (page 63). If the protective PE conductor is smaller
than 10 mm

, you must use a second earthing conductor. See section Grounding (page 17).

ABB recommends 360-degree grounding if shielded cable is used. Ground the other end
of the input cable shield or PE conductor at the distribution board.
3
ABB requires 360-degree grounding.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 AC power cables (page 63).

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. See section
Selecting the AC power cables (page 63).
Connecting its fourth conductor at the motor end increases bearing currents and causes extra
wear.
