Mounting the instrument Four M3 threaded screws are needed for mounting the

instrument (these are not accessories). The type of the
screws depends on the wall-material, while the dimensions
depend on the wall-thickness. The use of
pan head
screws is recommended to make the mounting
easier. The minimum screw-length should be the wall-
thickness + 10 mm.
During mounting, please observe all safety rules, and use
only appropriate tools.
Secure the screws against getting loose. For this purpose
you may use spring lock or serrated lock washers.
Depending on the material of the wall, and in order to
ensure the most practicable mounting method, it is not
mandatory, of course, to use the above-described threaded
joints. Depending on the situation, special screw types for
wood or for metal sheets can also be used, or the joint can
be riveted too.
1. Check if there are alien materials left in the housing, like
small tools, wire or metal pieces, plastic chips, etc. If there
are, remove them.
2. Put back the front cover of the instrument, taking care
that the sealing should get to its place. There should be no
gap, nor cables caught between the housing and the front
cover.
3. Tighten the front cover.
Turn the screws in clockwise direction. Tighten the screws
so much that ensures the desired sealing.
