Installation notes:
The sensor circuit is not infallibly galvanic isolated form the input circuit. However, the galvanic
isolation between the circuits is capable of withstanding a test voltage of 500Vac during 1
minute.
In a potentially explosive gas atmosphere, the transmitter shall be mounted in an enclosure in
order to provide a degree of protection of at least IP20 according to EN60529.
If the transmitter is installed in an explosive atmosphere requiring the use of equipment of
category 1 G, 1 M, or 2 M, and if the enclosure is made of aluminum, it must be installed such,
that even in the event of rare incidents, ignition sources due to impact and friction, sparks are
exclude: if the enclosure is made of non-metallic materials, electrostatic charging shall be
avoided.
For installation in a potentially explosive dust atmosphere, the following instructions apply:
The transmitter shall be mounted in a metal enclosure form B according to DIN43729 that is
providing a degree of protection of at least IP6X according to EN60529, that is suitable for the
application and correctly installed.
Cable entries and blanking elements shall be used that are suitable for the application and
correctly installed.
For an ambient te mperature ≥ 60°c, heat resistance cable shall be used with a rating of at least
20 K above the ambient temperature
The surface temperature of the enclosure is equal to the ambient temperature plus 20 K, for a
dust layer with a thickness up to 5 mm.
