4.1 General instructions

Each series 600 instrument consists of the actual signal
conditioning instrument as well as a plug-in socket for carrier
rail mounting. Because it has protection class IP 30 or IP 20,
the instrument is intended to be used in switching cabinets.

4.2 Mounting information

The plug-in socket is constructed for carrier rail mounting acc.
to EN 50022. Power supply is connected to terminals 17 and
18. For neighbouring series 600 signal conditioning instru-
ments, it is possible to continue connection L1 and N directly
via the supplied bridges.
Danger:
The bridges must never be used with single instruments or at
the end of a row of instruments. If this rule is not heeded, there
is a danger of coming into contact with the operating voltage or
causing a short circuit.
A VEGASCAN 693 in Ex version is an auxiliary, intrinsically
safe instrument and must not be installed in hazardous areas.
Before setup, the Ex separating chamber must be attached (as
shown below) with Ex versions. Safe operation can be only
ensured if the operating instructions manual and the EU type
approval certificate are observed. VEGASCAN 693 must not
be opened.
All signal conditioning instruments are provided with different
gaps depending on type and version (mechanical coding).
The plug-in socket is provided with coded pins that can be
inserted to prevent accidental interchanging of the various
instrument types.
With a VEGASCAN 693 in Ex version, the supplied coded pins
(type coded pin and Ex coded pin) must be inserted by the
user acc. to the below chart.
