The degree of protection of the Nivotester housing is IP 40, that of
the terminals IP 20. Where possible, the units should be mounted
in a switch cabinet or shady position
The limit switches use Minipac housings with snap-on fastenings
suitable for switch cabinet installation on a symmetrical (top hat)
rail. The rail corresponds to EN 50022-35x15 or EN 50022-35x7.5 .
Mount as follows:

The vertical spacing between adjacent rows of units must
exceed 25 mm.
•
Units can be mounted flush with each other provided the ambient
temperature (measured 1 cm above the unit) does not exceed
50 °C.
•
If a gap of 10 mm is left between adjacent units, an ambient
