classes T1, T2, T3, T4.
Safety of measuring indicator and scales using PUE C31H/EX
is guaranteed by such means as:
- power supply of the indicator
from power adapter ZRi02 II (2) G [EEx ib] IIC 06ATEX251
manufactured by RADWAG, and situated outside expolsive zone
or another power adapter with parameters adequate
for spark secured circuit.
- spark secured
casing of measuring indicator series PUE C31/H/EX, being in
conformity with norms: PN-EN 50014 and PN-EN 50020
and confirmed by a certificate KDB 06ATEX250
- application of
transducers with exposive safety certificates
- manufacturing
of the indicator according to requirements of a norm PN-EN
13463-1 on non-electrical elements of a scale
- user obligation to obey safety precautions
as indicated in the user manual of the measuring
indicator
CAUTION:
