Contents of this chapter
This chapter tells you how to install the power and control cables to the drive module. For 11 other electrical installation instructions that concern the drive, see the hardware manual.
Warnings
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death, or damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or maintenance work.

Use a separate grounding PE cable (1a) or a cable with a separate PE conductor (1b) if the conductivity of the shield does not meet the requirements for the PE conductor.
ABB recommends 360° grounding if shielded cable is used. Ground the other end of the input cable shield or PE conductor at the distribution board.
360° grounding is required.
Switch-disconnector and fuses. See the instructions on selecting the supply disconnecting device in the hardware manual.
Line contactor (optional)
Common mode filter (option +E208) d u /d t filter or sine filter (optional)
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. See the hardware manual.
External brake resistor
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. Connecting its fourth conductor at the motor end increases bearing currents and causes extra wear.

ACS880-31… +P940 drive modules
Connect the power cables as described in the hardware manual.
Cable connection procedure (IEC) – ACS880-01… +P940 and +P944 drive modules
This section gives instructions on how to connect the power cables. For US cabling instructions, see the quick installation guide.
■
Preparing the cable ends for connection and making 360-degree grounding at the cable entry plate
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.

WARNING!
Apply grease to stripped aluminum conductors before attaching them to non-coated aluminum cable lugs. Obey the grease manufacturer’s instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces.
3.
If fire insulation is used, make an opening in the mineral wool sheet according to the diameter of the cable.
4.
Put the cables through the entry plate.
5.
Remove rubber grommets from the entry plate for the cables to be connected. Cut adequate holes into the rubber grommets. Slide the grommets onto the cables. Slide the cables through the entry plate and attach the grommets to the holes.
6.
Attach the conductive sleeves to the cable shields with cable ties. Tie up the unused conductive sleeves with cable ties. An example of bottom entry is shown below. For top entry, place the grommet upwards.
