For alternatives, see hardware manual.1
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 hardware manual).

360° grounding is recommended if shielded cable is used. Ground the other end of the
input cable shield or PE conductor at the distribution board.
3
360° grounding is required.4
External brake resistor (for frames R4...R8 only).5
Use a separate grounding cable if the shield does not meet the requirements of IEC
61439-1 and there is no symmetrically constructed grounding conductor in the cable.
For more information, see hardware manual.

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 ter-
minal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable for motors above 30 kW. Earthing
at the motor increases bearing current and power consumption, damages the motor
bearing and even the motor.
