￭ 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.
Note:
The I/O of the supply/rectifier unit is mostly reserved for the internal use.
The following procedure instructs how to connect the control cables. In the example, the
power cables are routed to the cabinet through the bottom. Note that the figures in the
procedure are examples.
1.
Stop the drive and do the steps in section Electrical safety precautions (page 112) before
you start the work.
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 a cable gland or grommet.
• 360° grounding of the cable shield is recommended to suppress interference. In
case a grounding cable gland is available, remove the outer jacket of the cable
where it passes through the cable gland.
• Seal the cable with a grommet.
Note:
Note that the figure is an example of a control cable lead-through that has to be
acquired by the customer.

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.
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 a supply 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 114. 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 114.
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.
7. Twist the cable shields into bundles and connect them to the ground terminal nearest
to the terminal block. Keep the unshielded portion of the cables as short as possible.
8. Connect the conductors to appropriate terminals.
9. Fasten the shrouds (if any).
10. Close the doors.
