Connecting the control cables
See the control unit chapter for the default I/O connections. Note that the default I/O
connections can be affected by some options. See the circuit diagrams delivered with
the drive for the actual wiring.

Control cable connection procedure
WARNING!
Obey the safety instructions given in ACS880 multidrives cabinets and
modules safety instructions (3AUA0000102301 [English]). If you ignore
the safety instructions, 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.
1. Stop the drive (if running) and do the steps in section Electrical safety
precautions (page 44) before you start the work.
2. Put the control cables into the cabinet as described in section Grounding the outer
shields of the control cables 360° at the cabinet entry (page 66).
3. Route the control cables as described in section Routing the control cables inside
the cabinet (page 68).
4. Connect the control cables as described in section Connecting control
cabling (page 68).
Grounding the outer shields of the control cables 360° at the cabinet entry
Ground the outer shields of all control cables 360° with the EMI conductive cushions
at the cabinet entry. The grounding principle is the same for top and bottom entry
cables. The figures show the bottom entry. The actual design details can vary.
1. If necessary, temporarily remove the shrouding in front of the cable entry.
2. Put the cables in sequence from the smallest to the largest. This will help to achieve
a good contact with the cushions.
3. Loosen the tightening bolts of the EMI conductive cushions and pull them apart.
4. Cut holes in the grommets and put the cables through the grommets.
5. Peel the insulation from the part of the cable that will be in contact with the EMI
conductive cushion.
6. Put the cables between the cushions and attach them with cable ties for strain
relief.
7. Move the cushions back together.
8. Tighten the bolts to make sure that the EMI conductive cushions press tightly
around the peeled part of the cables.
