Installation Wall Mount Enclosure:
Ensure the installation is completed properly!
The most simple way to install a wall mount enclosure is to fasten a DIN rail with
a length of 210 mm (8.3 in.) and then to snap-on the enclosure.
It is possible to install the enclosure by using 3 screws as well. Use a pan head
screw with a head diameter of 5.5 ... 8.0 mm (0.22 ... 0.32 in.) for this. This
screw must be screwed into the mounting plate protruding 4 mm (0.16 in.). Then
hang the enclosure on the screw and additionally fix it with 2 more screws from
the terminal clamp housing. Please observe to screw them at least 40 mm into
the wall or 50 mm into appropriate dowels (to be set).
General
The wall mount enclosure can be equipped with cable glands and comes with
following installation parts:
− 1 glands M16 x 1.5
− 2 glands M20 x 1.5
With the supplied glands the following outer cable cross-sections can be con-
nected reliably:
− M16 x 1,5 3,5 mm – 10,5 mm
− M20 x 1,5 6,0 mm – 14,0 mm
To be able to use cable diameters outside of the tolerance, glands must be used
which ensure IP 65 minimum protection. Unused lead-ins have to be locked with
an appropriate dummy plug before the initial start-up.
In terms of electric connection please note the device configuration since un-
specified inputs, outputs as well as power supply connections are not connect-
ed.
