7. Tighten the cable gland.
8. At the motor, connect the cables according to instructions from the motor manufacturer.
Pay special attention to the phase order. For minimum radio-frequency interference,
ground the cable shield 360 degrees at the lead-through of the motor terminal box.

1) 360° grounding at cable lead-through
2) Use a separate grounding cable if the conductivity of the cable shield is less than 50% of the conductivity
of the phase conductor in a cable with no symmetrically constructed grounding conductor (see the document
ACS880 multidrive cabinets and modules, Electrical planning instructions [3AUA00000102324, English]).
Note: If there is a symmetrically constructed grounding conductor in 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. Connecting its fourth conductor at the motor end in-
creases bearing currents and causes extra wear.
