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 ter-
minal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable for motors above 30 kW. See section
Selecting the power cables (page 68).
Connecting its fourth conductor at the motor end increases bearing currents and causes
extra wear.

Connection procedure
The procedure of connecting the power cables to the standard drive is described
below. For the procedure with UK gland plate (option +H358), see also ACS880-11,
ACS880-31, ACH580-31 and ACQ580-31 UK gland plate (+H358) installation guide
(3AXD50000110711 [English]).
1. To remove the R3 front cover (R6 and R8 upper front cover), lift the cover from
the bottom outwards (1a) and then up (1b).
R3 – IP55R3 – IP21
To remove the R6 and R8 lower front cover, slide it downwards (3a) and then
forward (3b). For IP55 frame R8, disconnect the power supply wire of the
auxiliary cooling fan.
