Caution
Wall mounting may be a problem where vandals may destroy the unit (in
public garages, e.g.). Therefore, use steel fixing elements instead of the
dowels and screws included in the delivery.
Be sure to insert plugs into unused bushing holes to avoid water leakage
during facade cleaning, for example. Never leave the holes open for even
a short time (one day delay between mounting and cable connection, e.
g.).
Warning
Eliminate the risk of accident! Wall mounting is not suitable for narrow
passages or places where people's attention may be distracted. The
manufacturer shall not be liable for injuries incurred as a result of unsafe
mounting!
Select position with respect to the supply cables. Where the cables are installed
1.
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.
2.
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.
3.
Select the holes for cable supply. Select and mount the bushings depending on
4.
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
5.
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. Where
6.
cables lead along the surface, use the bushings included in the delivery.
