9. If fire insulation is used, make an opening in the mineral wool sheet according to the
diameter of the cable.
10. Slide the cables through the entries with the conductive sleeves. 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
entries with the conductive sleeves and attach the grommets to the holes.
Fasten the conductive sleeves to the cable shields with cable ties.
11. 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).
12. Tie up the unused conductive sleeves with cable ties.
13. Connect the twisted shields of the motor cables to the ground bar and the phase
conductors to the U2, V2 and W2 terminals.
14. For drives with external brake resistors (option +D150 and no +D151): Connect the
twisted shields of the resistor cables (if present) to the ground bar and the condutors to
the R- and R+ terminals.
15. Connect the twisted shields of the input cables and separate ground cable (if present)
to the PE terminal of the cabinet and the phase conductors to the L1, L2 and L3 terminals.
16.
Tighten the power cable screws to the torque given in Terminal and entry data for the
power cables on page 210.
17. Reinstall the shroud(s) and mounting plates.
￭ Connection procedure (US)
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.
1.
Do the steps in section Electrical safety precautions (page 18) before you start the work.
2. Open the cabinet door.
3. Open the swing-out frame (if installed).
4. Plan cable access and mark the conduit plate accordingly for the input and output power
and control cables.
