Use a separate grounding cable if the conductivity of the cable shield is < 50% of the conductivity
of the phase conductor and there is no symmetrically constructed grounding conductor in the
cable, see
Power cable types (page 66)

The drive module frame must be connected to the cabinet frame, see Grounding the drive mod-
ule (page 85)

If there is a symmetrically constructed grounding conductor in the motor cable in addition to the con-
ductive shield, connect the grounding conductor to the grounding terminal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the motor
end increases bearing currents and causes extra wear.

Preparing the cable ends and making 360-degree grounding at the
cable entry
1. Peel off 3…5 cm (1 1/4 … 2 in) of the outer insulation of the cables at the cable
entries with the conductive sleeves for the 360° high-frequency grounding.
2. Prepare the ends of the cables.
