Mounting and installation instructions
Mounting
Each series 600 instrument consists of a
plug-in socket for carrier rail mounting
EN 50 022 and a module unit.
The supply voltage can be connected to
terminals 17 and 18.
For neighbouring series 600 instruments it is
possible to continue connection L1 and N
directly via the supplied jumpers.
Note!
The jumpers must not be used with single
instruments or at the respective end of an
instrument row.
If this is not maintained, it is possible to come
in contact with the operating voltage or to
cause a short-circuit.
The power supply unit VEGASTAB 692 MD
must neither be installed in hazardous areas
nor used for power supply of sensors in
these areas.
Safe operation is only ensured if the operat-
ing instructions manual and the EC type
approval certificate are observed.
VEGASTAB 692 MD must not be opened.
