¬ II 3G EEx nL IIC T6 X
≤ 150 nF ; a cable length of 10 m is considered.
≤ 150 µH ; a cable length of 10 m is considered.
The apparatus has to be operated according to the appropriate data in the data
sheet and in this instruction manual. The data stated in the data sheet are
restricted by this operating instruction! The special conditions must be
observed!
Laws and/or regulations and standards governing the use or intended usage
goal must be observed. The sensor must only be operated with an energy-lim-
ited circuit, which satisfies the requirements of IEC 60079-15. The explosion
group complies with the connected, supplying, power limiting circuit.
No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.

The sensor must not be mechanically damaged.
When used in the temperature range below -20°C the sensor should be pro-
tected from knocks by the provision of an additional housing.
The connection parts are to be installed, such that a minimum protection class
of IP20 is achieved, in accordance with IEC 60529.
