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 and sensor
can be made with standard two-wire cable.
- If strong electromagnetic interferences are
expected, screened cable is recom-
mended. 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.
- The voltage supply of VEGAMET must
provide extra-low voltage to ensure pro-
tection class II. When using VEGASTAB
593, a reliable separation from the mains
circuits acc. to DIN VDE 0106, part 101 is
ensured.
