Safety instructions
Ex installation:
•For a safe installation of the YTA80 in hazardous area the following must be
observed. The module must only be installed by qualified personnel who are
familiar with the national and international laws, directives and standards that
apply to this area.
•The sensor circuit is not infallibly galvanically isolated from the Fieldbus input
circuit. However, the galvanic isolation between the circuits is capable of
withstanding a test voltage of 500Vac during 1 minute.
•Production year of the transmitters can be taken from the first 2 digits of the
serial number.
•There are no user serviceable parts inside the transmitters.
•The transmitter YTA80/KS2 must be mounted in an enclosure in order to
provide a degree of ingress protection of at least IP20. If the transmitter is
installed in a potentially explosive atmosphere where equipment category 1G
is required and if the enclosure in which the transmitter is mounted is made of
aluminium, then the requirements of EN 50284, clause 4.3.1 must be taken into
account.
•YTA80/KS2 may only be installed in a potentially explosive atmosphere
caused by the presence of combustible dust when mounted in a metal
enclosure form B according to DIN 43729 that is providing a degree of ingress
protection of at least IP 6X in accordance with EN 60529, that is suitable for
the application and is correctly installed.
•Cable entries and blanking elements shall be used that are suitable for the
application and correctly installed.
•For an ambient temperature ≥ 60°C, heat resistant cables shall be used with a
rating of at least 20K above the ambient temperature.
•The surface temperature of the enclosure is equal to the ambient temperature
plus 20K, for a dust layer with a thickness up to 5 mm.
•The transmitter YTA80/KS2 shall be mounted in an enclosure providing a
degree of ingress protection of at least IP54 in accordance with EN 60529.
•Provisions must be made to prevent the rated supply voltage being exceeded
by more than 40%.

Installation notes.
The sensor circuit is not infallibly galvanic isolated from 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 1G
and 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 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 temperature  60ºC, heat resistant cables 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
