Connecting the control cables
Default I/O connection diagram
See chapter Control units of the drive.
Connection procedure
Note: The instructions below are based on an example cabinet construction. They are not
applicable to all possible solutions but only clarify the principles. See the circuit diagrams
delivered with the supply unit.
Note: The I/O of the supply unit is mostly reserved for the internal use.
The following procedure instructs how to connect the control cables of the unit. In the
example, the power cables are routed to the cabinet through the bottom. Note that the
figures in the procedure are examples.
WARNING! Repeat the steps described in section Electrical safety
precautions on page 128. The complete safety instructions are given in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). If you ignore them, physical injury or death, or damage to
the equipment can occur.
1. Repeat the steps described in section Electrical safety precautions on page 128.
2. Open the cubicle door.
3. Remove the shrouds (if any) from the cubicle.
4. Run the cables into the inside of the cabinet through EMI conductive cushions.
• Run the cables between the cushions. Strip the cable at this location to enable
proper connection of the bare shield and the cushions. Tighten the cushions firmly
onto the cable shields.
• Seal the cable with a grommet.
5. Run the cables to the appropriate terminals. Wherever possible:
• Use the existing cable trunking in the cabinet.
• Use sleeving wherever the cables are laid against sharp edges.
• Tie the cables to provide strain relief.
6. Cut the cables to suitable length. Strip the cables and conductors.

lead-through that has to be acquired by the
customer.
