3.1 Connection instructions
Note the following instructions for electrical
connection:
- The connection must be made acc. to the
local installation standards (e.g. in Ger-
many acc. to the VDE-regulations).
- The wiring between VEGAMET 614 V and
sensor can be made with standard two-
wire cable.
- If strong electromagnetic interferences are
expected, we recommend the use of
screened cable. The screening must be
earthed on both ends.
- The line resistances stated in the technical
data must not be exceeded.
- If overvoltages are expected, we recom-
mend a sensor electronics with integrated
overvoltage protection or the installation of
VEGA overvoltage arresters.
Connection instructions for Ex
approved applications
When wiring between VEGAMET 614V Ex
and an explosion protected sensor, the in-
stallation rules, in Germany acc. to VDE 165
and the EC type approval certificate must be
observed. The official documents are sup-
plied with the respective instrument.
