4 Mounting

4.1 General instructions

The source container is part of the measuring system. In case the

source container is already equipped with an active isotope, the

source container must be locked before mounting.

Danger:

Before mounting; make sure that the source is securely closed. Use

a padlock to secure the source container in the closed condition and

prevent it from being inadvertently opened.

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

•

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

Make sure that all parts of the instrument exposed to the process are

suitable for the existing process conditions.

These are mainly:

•

Active measuring component

•

Process tting

•

Process seal

Process conditions are particularly:

•

Process pressure

•

Process temperature

•

Chemical properties of the medium

•

Abrasion and mechanical inuences

You can nd the specications of the process conditions in chapter

"Technical data" as well as on the nameplate.

In the case of instrument housings with self-sealing NPT threads, it is

not possible to have the cable entries screwed in at the factory. The

openings for the cable glands are therefore covered with red protec-

tive caps as transport protection.

Prior to setup you have to replace these protective caps with ap-

proved cable glands or close the openings with suitable blind plugs.

The suitable cable glands and blind plugs come with the instrument.
