15.2.1
General information on explosion protection
The electrical connection is made via a plug in a separate inductively coupled
electronics compartment - exclusively in intrinsically safe systems. The
electronics option HA is combined with the electronics models ZOK-E * M
(compact version) or ZOK-E * K (remote electronics) in accordance with LOM 16
ATEX 2062 to form the electronics options 1A, 2A, 3A and 5A.
Permitted use
The intrinsically safe flow meter can be used as follows:
In Zone 2 (Gas-Ex, Category 3G, EPL Gc) in explosion groups IIA, IIB and
IIC.
The requirements for simple electrical equipment in intrinsically safe circuits
in Zone 1 according to EN 60079-11 are met for various versions.
The qualification with regard to the surface temperature is T4 / T3; for all
gases, vapours and fog with an ignition temperature ≥ 135 ° C / ≥ 200 ° C, the
products are not an ignition source.
The permissible ambient temperature range is from -20 ° C ≤ Ta ≤ 80 ° C.
In accordance with the installation regulations, housing must be grounded using
the earthing clamps. The maximum connection cross-section is 4 mm
