Connecting the control cables
See chapter Control units of the drive (page 123 ) for the default I/O connections of the
inverter unit (with the ACS880 primary control program). The default I/O connections can
be different with some hardware options, see the circuit diagrams delivered with the drive
for the actual wiring. For other control programs, see their firmware manuals.

Control cable connection procedure
WARNING! Obey the instructions in chapter Safety instructions . If you ignore
them, injury or death, or damage to the equipment can occur.
1. Stop the drive (if running) and do the steps in section Precautions before electrical
work (page 21 ) before you start the work.
2. Run the control cables into the auxiliary control cubicle (ACU) as described in section
Grounding the outer shields of the control cables at the cabinet lead-through below.
3. Route the control cables as described in section Routing the control cables inside the
cabinet (page 95 ).
4. Connect the control cables as described starting on page 95 .
Grounding the outer shields of the control cables at the cabinet lead-through
Ground the outer shields of all control cables 360 degrees at the EMI conductive cushions
as follows:
1. Loosen the tightening screws of the EMI conductive cushions and pull the cushions
apart.
2. Cut adequate holes to the rubber grommets in the lead-through plate and lead the
cables through the grommets and the cushions into the cabinet.
3. Strip off the cable plastic sheath above the lead-through plate just enough to ensure
proper connection of the bare shield and the EMI conductive cushions.
4. Tighten the two tightening screws so that the EMI conductive cushions press tightly
round the bare shield.
