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.
Special conditions
Maximum operating current I

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 against transients
Ensure transient protection is provided and that the maximum value of the transient pro-
tection (140% of 85 V) is not exceeded.
Electrostatic charge
Electrostatic charges must be avoided on the mechanical housing components. Dan-
gerous electrostatic charges on the mechanical housing components can be avoided by
incorporating these in the equipotential bonding.
Material selection accessories
When selecting accessories, ensure that the material allows the temperature of the
enclosure to rise to up to 70 °C.
Plug connector
The plug connector must not be withdrawn under voltage. The proximity switch is identi-
fied as follows: "WARNING - DO NOT SEPARATE WHEN ENERGIZED". With the plug
connector disconnected, soiling of the internal area must be prevented.(i.e. the area that
is inaccessible when the connector is inserted)
