The requirements specified in EN 60079-14 must be observed dur-
ing use / installation.
According to Directive 94/9/EC (ATEX 95) Appendix I, the O
sensor plug-in heads include in the O
the devices of equipment group II, category 1/2D which, according
to Directive 99/92/EC (ATEX 137) can be used in zones 20/21
or 21/22 or 21 or 22, which are potentially explosive due to
combustible dust.
The requirements specified in EN 60079-14 must be observed dur-
ing use/ installation.
The digital version of the O
to and operated by two-wire cable to the certified transmitter.
The intrinsically safe circuits are galvanically isolated from the non-
intrinsically safe circuits up to a nominal voltage peak value of
375 V and from the earthed parts up to a nominal voltage peak
value of 30 V.
