Use is restricted to the following stated conditions
General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruction manual.
The maximum surface temperature has been determined in accordance with method A without a dust layer on the equipment.
The data stated in the data sheet are restricted by this operating instruction!
The special conditions must be adhered to!
Installation, commissioning Laws and/or regulations and standards governing the use or intended usage goal must be observed.
The adhesive label provided must be affixed in the immediate vicinity of the sensor! The surface to which the label is applied
must be clean, flat and free from grease! The affixed adhesive label must be readable and durable, taking account of the possi-
bility of 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

The maximum permissible load current must be restricted to the values given in the following list.
High load currents and load short-circuits are not permitted.
Maximum operating voltage U

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.
Electrostatic charge
Electrostatic charges must be avoided on the mechanical housing components. Dangerous electrostatic charges on the
mechanical housing components can be avoided by incorporating these in the equipotential bonding.
Plug connector
The plug connector must not be withdrawn under voltage. The proximity switch is identified 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)
The plug connection can only be separated using a tool. This is achieved by using the locking protection V1-Clip (Mounting
accessory from Pepperl + Fuchs).
