Peel a cable according to the 1:2 peeling indicator
and expose the shield layer.
Loosen a wire clip.
Route the cable through the rubber ring and wire clip
and fix the cable in the waterproof cable trough.
Tighten the wire clip and ensure that the wire clip is
completely pressed against the shield layer with no
contact of the sheath.
The shield layer is not
exposed.
The peeling size is larger than the 1:2 peeling
indicator and the exposed shield layer extends to
the waterproof cable trough, which fails the

The cable is not fixed
with a wire clip.
