Axis 2N IP Verso Installation Manual page 55

Caution
Make sure that the diameter of the dowel holes is accurate to avoid
falling out of the dowels! Use the mounting glue to secure the dowels if
necessary.
Make sure that the depth of the dowel holes is accurate!
Do not use low-quality dowels to avoid their pulling out of the wall!
Having removed the front panel, make sure that no dirt gets inside the
product (especially onto the sealing surface).
®
Never turn 2N IP Verso to align the box assembly after mounting. Make
sure that the flush mounting boxes have been installed accurately.
Check the plasterboard wall and room interior pressure values. If the
difference between the values is too great (as a result, e.g., of
overpressure ventilation), separate the intercom using, for example, the
mounting box enclosed and seal the cable passage to avoid speaker
damage.
Surface mounting may cause problems on places exposed to potential
vandalism (such as public garages, etc.). In this case, use steel anchoring
elements instead of the dowels and screws included in the delivery.
Make sure that the installation surface is perfectly flat with the maximum
inequality of 0.5 mm. (e.g. boards, glass, cut stone, etc). If this is not the
case, use a flush mounting backplate, Part No 9155061 9155067, – or level
the wall surface.
Always use an installation backplate for uneven installation surfaces.
While flush mounting, make sure that the frame does not touch the wall
and keeps the same wall distance on all sides. Otherwise, the weather
resistance can be considerably impaired. We do not recommend you to
install the device until you have treated the wall properly.
Any intentional mechanical damage (drilling, main unit tampering, etc.)
results in a loss of warranty.
