1 For alternatives, see hardware manual.
2 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).
3 360° grounding is recommended if shielded cable is used. Ground the other end of the input
cable shield or PE conductor at the distribution board.
4 360° grounding is required.
5 External brake resistor (for frames R4...R8 only).
6 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 in-
formation, 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 terminal 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.
