4.1 General instructions

Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" or on the
type label.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your VEGADIF 65 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.
The ventilation for the electronics housing is realised via a filter
element in the vicinity of the cable glands.

Information:
Make sure that the filter element is always free of buildup during
operation. A high-pressure cleaner must not be used for cleaning.
