3 Mounting

3.1 General instructions for use of the instrument

Protect your instrument against moisture penetration through the fol-

lowing measures:

•

Use the recommended cable (see chapter "Connecting to power

supply")

•

Tighten the cable gland

•

Turn the housing in such a way that the cable gland points down-

ward

•

Loop the connection cable downward in front of the cable gland

This applies particularly to:

•

Outdoor mounting

•

Installations in areas where high humidity is expected (e.g. through

cleaning processes)

•

Installations on cooled or heated vessels

3.2 Ventilation and pressure compensation

The lter element is mounted into the electronics housing. It has the

following functions:

•

Ventilation of the electronics housing

•

Atmospheric pressure compensation (with relative pressure meas-

uring ranges)

→

Turn the housing so that the lter element points downward after

the instrument is installed. This provides better protection against

buildup.
