Power cable connection procedure (IEC)
This section gives instructions on how to connect the power cables for ACS880-01
+P940 and +P944. Connect the power cables for ACS880-11 +P940 and ACS880-31
+P940 as described in the hardware manual. For US cabling instructions, see also
the quick installation guides.
1. Do the steps in section Safety instructions on page 9 before you start the work.
2. Open the cabinet door.
3. Peel off 3 to 5 cm of the outer insulation of the cables above the bottom plate of
the cabinet for the 360° high-frequency grounding. See page 30.
4. If fire insulation is used, make an opening in the mineral wool sheet according to
the diameter of the cable.
5. Put the cables through the entries with the conductive sleeves.
6. Attach the conductive sleeves to the cable shields with cable ties.
7. Seal the slot between the cable and mineral wool sheet (if used) with sealing
compound (eg, CSD-F, ABB brand name DXXT-11, code 35080082).
8. Tie up the unused conductive sleeves with cable ties.
9. Prepare the ends of the cables.
5 Line contactor (optional)
6 Common mode filter (option +E208)
7 du/dt filter or sine filter (optional)
8 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.
9 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.
