VEGASEL 643 7
Mounting
Each series 600 signal conditioning instrument con-
sists of a terminal socket for carrier rail mounting DIN
46 277 and a module instrument.
The supply voltage can be connected to terminals 9
and 10.
For neighbouring series 600 signal conditioning
instruments it is possible to provide and loop the
connection L1 and N directly via the supplied bridges.
The same is valid for the connection VEGAMET-
voltage output 0 … 10 V to VEGASEL-voltage input
0 … 10 V /terminals 7 and 8).
Note, danger!
Never use the bridges with single instrument or at the
end of an instrument row. They may come in touch
with the operating voltage or cause a shortcircuit.
Coding
The terminal socket must be provided with pins and
the signal conditioning instrument with appropriate
gaps (mechanical coding) to avoid interchanging of
the individual signal conditioning instruments.
An instrument coding ensures that interchanging
among the signal conditioning instruments is avoided
by differently positioned coded keys.
