Wall (surface) mounting is used where flush mounting is inapplicable (in concrete and
steel structures, entry barrier columns, etc.). The frame is not used.
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!
