4.2 Minimum space requirement
In order to ensure sufficient ventilation of the device, clearance on all sides of at least 50 mm has to
be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance
applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating exists. This
layout is only then permissible when the air suctioned from the upper unit does not become warmer
than the permissible ambient temperature, see Technical data. I.e., a correspondingly larger clearance
or thermal shielding is required.
4.3 Fastening the device
The type of fastening and the number of fastening points are dependent on the housing design. All the
fastening points available must be used for safe fastening.
Proceed as follows:
Type FSDM2.5M
Fastening at 3 points
" Drill fastening point “1”.
" Screw in flat-head screw up to a distance of approx. 2 mm and mount the device.
" Remove the terminal compartment cover.
" Align the device and mark the position of both lower fastening points “2” + “3”.
" Remove the device and drill the fastening points “2” + “3”.
" Remount the device and tighten the fastening point screws “2” + “3”.
