Routing The Control Cables Inside The Cabinet (Frames R10 And R11); Connecting The Control Unit Cables - ABB ACS880-07 Series Hardware Manual

Routing the control cables inside the cabinet (frames R10 and R11)

Use the existing trunking in the cabinet wherever possible. Use sleeving if cables are laid
against sharp edges. When running cables to or from the swing-out frame, leave enough
slack at the hinge to allow the frame to open fully.
Note: Leave some slack in the control wiring to allow the removing of the control unit
assembly plate when the drive module is replaced.

Connecting the control unit cables

Note: Keep any signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.
Note: For frames R10 and R11: Leave slack to the control wires to make it possible to lift
the control unit mounting plate a little when the drive module is replaced.
Units without additional I/O terminal block (option +L504): Ground the pair-cable shields
and all grounding wires to the clamp below the control unit as shown below.
