Input power cable3
Two protective earth (ground) conductors. Drive safety standard IEC/EN 61800-5-1 requires
two PE conductors for a fixed connection, if the cross-sectional area of the PE conductor
is less than 10 mm

Cu or 16 mm
2
Al. For example, you can use the cable shield in addition
to the fourth conductor.
4
Separate PE cable (line side). Use a separate grounding cable or a cable with a separate
PE conductor for the line side, if the conductivity of the fourth conductor or shield does not
meet the requirements for the PE conductor.
5
Motor cable
Note: ABB recommends to use a symmetrical shielded cable (VFD cable) as the motor
cable.
6
Separate PE cable (motor side). Use a separate grounding cable for the motor side, if the
conductivity of the shield is not sufficient, or if there is no symmetrically constructed PE
conductor in the cable.
7
360-degree grounding of the cable shield. Required for the motor cable and brake resistor
cable (if used), recommended for the input power cable.
