11. Connect the conductors to the appropriate detachable terminals of the control
unit. See the default I/O diagram in chapter Control unit (page 135). Use shrink
tubing or insulating tape to contain any stray strands. Tighten the screws to secure
the connection.
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.
