Protection by enclosure "tc" Some of the information in this instruction manual is more
specific than the information provided in the datasheet.
Ge n e r a l The corresponding datasheets, declarations of conformity, EC-type examination certifi-
cates, certifications, and control drawings, where applicable (see datasheets), form an
integral part of this document. These documents can be found at www.pepperl-
fuchs.com. The maximum surface temperature of the device was determined without a
layer of dust on the apparatus. Some of the information in this instruction manual is more
specific than the information provided in the datasheet.
Installation, commissioning Laws and/or regulations and standards governing the use or intended usage goal must
be observed. If the Ex-relevant identification is printed exclusively on the adhesive label
provided, this label must be affixed in the immediate vicinity of the sensor! The back-
ground surface to which the adhesivelabel is to be applied must be clean and free from
grease! The applied label must be durable and remain legible, with due consideration of
the possibility of chemical corrosion!
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.

Protection from mechanical danger
The sensor must not be exposed to ANY FORM of mechanical danger.
Protection from UV light
The sensor and the connection cable must be protected from damaging UV-radiation.
This can be achieved when the sensor is used in internal areas.
Protection of the connection cable
The connection cable must be prevented from being subjected to tension and torsional
loading.
Electrostatic charge
Do not attach the nameplate provided in areas where electrostatic charge can build up.
