Preparing the cable openings
The cables can be fed through openings on the
back of the housing or the underside of the
housing. The openings are pre-cut and must be
prepared as required before mounting.
You can prepare the cable openings on the
back of the housing as follows:

plastic bridge as described below.
- If the opening of a strain relief is too large,
e.g. for thin cables, turn the strain relief frame
(bend it downwards).
- Only use strain reliefs with cabling through
the underside of the housing. For cabling
through the back of the housing, use external
strain reliefs.
