The 4 pair cable must be looped once through the ferrite core before being connected to the door panel board. The
ferrite core suppresses Electro Static Discharge (ESD) transients which could otherwise travel down the wiring and
cause damage to components in the door panel.

Two separate cables should be installed from the controller to the door panel; a 4 pair CW1308 cable for the Line A/B
& 12V/0V power and a 2.5mm Earth. IMPORTANT: Never use spare pairs in the multi‐core cable for the Earth
