VMS user manual
Installation of the supporting frame:
Wall mounting of small units can be made using stainless steel fixing brackets. For
mounting and handling of units of more than five enclosures, a supporting frame is
compulsory.
- The supporting frame consists of at least two horizontal C-profiles (= the length of the
assembly width) and a number of two vertical C-profiles (equal to the number of vertical
sections +1).
- If the unit height is greater than 1000 mm, three horizontal C-profiles will be used.
- The vertical C-profiles are 140 mm longer than the height of the assembled panel.
- The frame and the enclosure assembly should be mounted simultaneously.
Horizontal and vertical C-profiles of the first row of enclosures are assembled together
by clamping brackets and sliding nuts. The next clamping brackets are mounted on the
horizontal profile.
The first row of enclosures is then mounted on the vertical profiles with the clamping
plates.
