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 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 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.
