S
elect an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
U
se the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
Y ou can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

T he reference plane for the measuring range of the sensors is the
bearing surface on the side of the focussing lens. With the version with
adapter flange, the reference plane is the lower side of the flange.
