Select position with respect to the supply
cables. Where the cables are installed
inside a structure or wall, use the hole at
the intercom bottom.
Drill holes of the depth of 70 mm for
dowels in the wall as shown in the figure.
Push or hammer the enclosed dowels into
the drilled holes. Use some suitable
building adhesive if the dowels are too
loose. Use fixing elements of your own for
steel structure surface mounting (metric
screws + nuts, e.g.).
Remove the front panel from the
intercom.
Select the holes for cable supply. Select
and mount the bushings depending on the
cables: 2-hole bushing or 1-hole bushing
or both. Insert the blanks in the other
holes.
Put the intercom on the wall/structure
while introducing cables inside. Leave
some of the cables inside the unit as a
reserve. Insert the plugs in the unused
bushings and tighten the bushing nuts
carefully.
Do not complete mounting until you have
finished electrical installation – refer to
Mounting Completion. Where cables lead
along the surface, use the bushings
included in the delivery.
