2 Safety notes
- The transmitter must be set up and operated in accordance with
this operating manual and the regulations and standards relating
to it.
- The transmitter is intended for rail mounting outside the
hazardous area.
Supply and output of the transmitter must be located in the non-
intrinsically safe zone.
- In accordance with equipment group “II” category “(1) G D”, the
sensor circuit may be located in Zone 0 (20), Zone 1 (21) and Zone
2 (22).
- Field devices connected to the sensor circuit for use in areas with
a dust explosion hazard require a separate type examination.
- Equipment for potentially explosive areas which contain hybrid
mixtures has to be especially checked for this use. Hybrid
mixtures are potentially explosive mixtures out of combustible
gases, vapors, or mists with combustible dust. The operator
bears the responsibility of checking if the equipment is suitable
for such uses.
- Input, output and other configuration parameters can be freely set
through the PC program, via an interface.
- The maximum permissible ambient temperature for the
transmitter is +60°C.
- The transmitter must be set up in such a way as to provide at
least IP20 protection as per EN 60 529, also for the connecting
parts.
- During setting up and operation of the transmitter, any build-up of
electrostatic charge must be avoided.
- The intrinsically safe sensor circuit is safely isolated from the non-
intrinsically safe circuits, up to a peak value of 375V of the
nominal voltage.
