4.1 General instructions

Make sure that all parts of the instrument in contact with the measured
product, especially the sensor element, process seal and process
fitting, are suitable for the existing process conditions such as process
pressure, process temperature as well as the chemical properties of
the medium.
You can find the specifications in chapter "Technical data" in the or on
the type label.
Select 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°).
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You 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.

Ventilation for the measuring cell is realised by means of a filter
element in the socket of the electronics housing. Ventilation for the
electronics housing is realised via an additional filter element in the
area of the cable glands.
