General installation instructions
To avoid risk of ignition during installation and maintenance appropriate safety measures
against electrostatic discharge (ESD) are to be considered.
The sensor circuit is not infallibly galvanic isolated from the supply output circuit. However, the
galvanic isolation between the circuits is capable of withstanding a test voltage of 500Vac
during 1 minute.
For installation in a potentialy explosive gas atmosphere, the following instructions apply:
If the transmitter is applied in type of protection "Ex nA", it shall be installed in an enclosure
that is Ex nA certified according to IEC-EN 60079-15, or "Ex e" certified and suitable for the
application and correctly installed.
Cable entry devices and blanking elements shall fulfill the same requirements
For installation in a potentially explosive dust atmposphere, the following instructions apply:
If the transmitter is supplied with an intrinsically safe signal "ic" and interfaces an intrinsically
safe signal "ic" (e.g. a passive device), the transmitter shall be mounted in a metal enclosure
that provides a degree of protection of at least IP6X according to EN/IEC 60529, and that is
suitable for the application. Cable entry devices and blanking elements shall fulfill the same
requirements. The surface temperature of the enclosure is equal to the ambient temperature
+20K for a dust layer with a maximum thickness of 5 mm.
