Routing the control cables inside the cabinet (frames R10 and R11)
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: 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.
Drives without additional I/O terminal block (option +L504):
Ground the pair-cable shields
and all grounding wires to the clamp next to the control unit as shown below.
