Use is restricted to the following stated conditions
Ge n e r a l 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!
Installation, commissioning Laws and/or regulations and standards governing the use or intended usage goal must
be observed. If the Ex-related marking is printed only on the supplied label, then this
must be attached in the immediate vicinity of the sensor. The sticking surface for the
label must be clean and free from grease. The attached label must be legible and indel-
ible, including in the event of possible 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.
Protection against transients
Ensure transient protection is provided and that the maximum value of the transient pro-
tection (140% of 85 V) is not exceeded.
Material selection accessories
When selecting accessories, ensure that the material allows the temperature of the
enclosure to rise to up to 70 °C.
