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 instructions
The plug-in socket is designed for carrier rail mounting according to
EN 50022. The operating voltage is connected to terminals 17 and 18.
For neighbouring series 600 instruments it is possible to continue
connection L1 and N directly via the supplied bridges. Max. five
instruments can be connected through in this way.
Danger:
Looping through via bridges is only allowed for operating voltage
(sockets L1 and N). The bridges must never be used with single
instruments, at the end of a row of instruments or with other sockets. If
this rule is not heeded, there is a danger of coming into contact with
the operating voltage or causing a short circuit.
A VEGAMET 624 in Ex version is an auxiliary, intrinsically safe
instrument and may not be installed in explosion-endangered 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 EG type approval certificate are
observed. VEGAMET 624 must not be opened.
All signal conditioning instruments are provided with different gaps
dependent 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 VEGAMET 624 in Ex version, the supplied coded pins (type
coded pin and Ex coded pin) must be inserted by the user according to
the below chart.
