INSTALLATION NOTES
SAFETY INSTRUCTIONS
For safe installation of MBT 9110 084Z7443 the following must be observed. The module shall only be Installed by qualified
personnel who are familiar with the national and international laws, directives and standards that apply to this area.
Year of manufacture can be taken from the first two digits in the serial number.
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 500 VAC 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 ≥ 60 °C, 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.
