4.1 General ins

tructions

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.

Caution:

After removal

of the diaphragm protective cover, the diaphragm must

not be pressed.

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.
