WARNING! Repeat the steps described in section Electrical safety
precautions on page 42 . The complete safety instructions are given in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). Ignoring the instructions can cause physical injury or death,
or damage to the equipment.
1. Repeat the steps described in section Electrical safety precautions on page 42 .
2. Open the door of the DC/DC converter cubicle and remove the shrouding.
3. Run the control cables into the cubicle as described in section Grounding the outer
shields of the control cables at the cabinet lead-through below.
4. Route the control cables to the control connection terminals. Use the existing trunking
in the cabinet wherever possible. Use sleeving if cables are laid against sharp edges.
5. Connect the control cables. See chapter Control unit and the circuit diagrams
delivered with the drive.
6. Refit any shrouds removed earlier and close the door of the cubicle.
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. Slacken 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 make
sure that the connection of the bare shield and the EMI conductive cushions is proper.
