Control cable connection procedure
WARNING!
Obey the safety instructions given in ACS880 multidrive 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 46) before you start the work.
2. Run the control cables into the cabinet as described in section Grounding the outer
shields of the control cables at the cabinet entry below.
3. Route the control cables as described in section Routing the control cables inside the
cabinet .
4. Connect the control cables as described in section Connecting control cabling .
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.
