Installation instructions
The sensor circuit is not infallibly galvanically isolated from the Field-
bus input circuit. However, the galvanic isolation between the circuits
is capable of withstanding a test voltage of AC 500 V 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 IP 20 according to EN 60 529.
