Mounting and installation instructions
Mounting
Each series 600 instrument consists of a
terminal socket for carrier rail mounting DIN
46 277 and a module unit.
You can connect the supply voltage to termi-
nals 9 and 10.
If there are adjoining series 600 instruments,
it is possible to continue the connection L1
and N directly via the supplied jumpers.
Note!
The jumpers must never be used for single
instruments or at the end of an instrument
row.
Disregard of this warning could lead to com-
ing into contact with the operating voltage, or
could generate a short circuit.

Coding
The terminal socket is provided with pins and
the instrument with appropriate gaps (me-
chanical coding) to prevent inadvertent
swapping of the different instruments.
Instrument coding by means of differently
placed coded pins prevents inadvertent
swapping of the different signal conditioning
instruments and this power supply unit.
