Mounting
Each series 600 signal conditioning instru-
ment consists of a terminal socket for carrier
rail mounting DIN 46 277 and a module unit.
The supply voltage can be connected to the
terminals 9 and 10 of the terminal socket.
If there are adjoining series 600 instruments,
it is possible to continue the connection L1
and N via the supplied jumpers.
Note!
The jumpers must never be used on single
instruments or at the respective end of a row
of instruments, as there is the danger of
coming into contact with the supply voltage,
or of causing a short circuit.
The signal conditioning instrument must al-
ways be mounted outside hazardous areas
or special Ex protective measures must be
taken.
Transparent cover
To protect the instrument against unauthor-
ised or inadvertent use, the front plate of
VEGATOR can be provided after setup with a
lockable transparent cover. To remove
transparent cover, see drawing below.

Coding
To avoid inadvertent swapping of the differ-
ent signal conditioning instruments, the termi-
nal socket is provided with pins and the
signal conditioning instrument with appropri-
ate gaps (mechanical coding). An instrument
coding with coded pins in different positions
ensures that the various signal conditioning
instruments cannot get mixed up.
Ex instruments
An Ex coding with fixed coded pin
ensures that non Ex and Ex instru-
ments cannot get mixed up.
The coding is part of the explosion protec-
tion: On VEGATOR… Ex the supplied coded
pins (instrument coded pin and Ex coded
pin) must be inserted by the user according
to the table below.
