Installation notes.
For installation in a potentially explosive gas atmosphere, the following instructions apply:
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.
The transmitter shall be mounted in an enclosure form B according to DIN43729 or equivalent
that is providing a degree of protection of at least IP20 according to IEC 60529 that is suitable
for the application and correctly installed.
If the enclosure is made of aluminium, it must be installed such, that even in the event of rare
incidents, ignition sources due to impact and friction, sparks are excluded.
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 or
equivalent, that is providing a degree of protection of at least IP6X according to IEC 60529 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 temperature ≥ 60ºC, heat resistant cables shall be used with a rating of at least
20 K above the ambient temperature.
For installalation in mines the following instructions apply:
The transmitter shall be mounted in a metal enclosure that is providing a degree of protection
of at least IP6X according to IEC 60529, and 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
The enclosure shall not contain by mass more than
a) 15 % in total of aluminium, magnesium, titanium and zirconium, and
b) 7,5 % in total of magnesium, titanium and zirconium.
