CE conformity
VEGAMET signal conditioning instruments meet the protective regulations of EMC
(89/336/EWG) and NSR (73/23/EWG). Conformity has been judged acc. to the following
standards:
EMC
Emission EN 50 081 - 1: 1992
Susceptibility EN 50 082 - 2: 1995
NSR EN 61 010 - 1: 1993

The intrinsically safe circuits are reliably separated from the non intrinsically safe circuits up
to a peak voltage of 375 V.
The max. voltage on the non intrinsically safe circuits should not exceed 250 V

in case of
failure.
