3.1 Connection instructions
For electrical connection, you should always
observe the following instructions:
- The connection must be made according to
the appropriate national installation stand-
ards (e.g. in Germany acc. to the VDE
regulations).
- The wiring between VEGASTAB 692 MD
and the sensors can be standard two-wire
cable.
- If electromagnetic interference is expected,
the use of screened cable is recom-
mended. The screening must be earthed at
one sensor end.
- The line resistances stated in the technical
data must not be exceeded.
- If overvoltages are expected, we recom-
mend a sensor electronics module with
integrated overvoltage protection or the
installation of VEGA overvoltage arresters.
- When connecting more than one sensor
(max. 15), it is obligatory to connect (be-
fore complete connection) each sensor
individually to VEGASTAB 692 MD and to
assign a different address to each sensor
(1-15) via the software VVO (see chap. "4
Setup").
- Make sure when connecting
VEGACONNECT 3 to a modem that the
modem connection cable for
VEGACONNECT 3 (MODEM.KX) is used.
