Connecting the control cables
See chapter
Control units of the drive (page 105)
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
. 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
before you start the work.

below.
3.
Route the control cables as described in section
Routing the control cables inside the
4.
Connect the control cables as described in section
Connecting control cabling (page 87)
Grounding the outer shields of the control cables at the cabinet entry
Ground the outer shields of all control cables 360 degrees at the EMI conductive cushions
as follows (example constructions are shown below, the actual hardware may vary):
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 entry plate and put the cables through
the grommets and the cushions.
3.
Strip off the cable plastic sheath above the entry 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.

Note 1:
Keep the shields continuous as close to the connection terminals as possible.
Secure the cables mechanically at the entry strain relief.
Note 2:
If the outer surface of the shield is non-conductive:
