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 indelible, including in the event of possible chemical corrosion. After opening the housing,
you should check that the seal is in the correct position and is clean and intact before
closing the housing again.
Repairs to these apparatus are not possible. After opening the housing, you should
check that the seal is in the correct position and is clean and intact before closing the
housing again.

The sensor must not be exposed to ANY FORM of mechanical danger.
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.
Ensure transient protection is provided and that the maximum value of the transient pro-
tection (140% of 85 V) is not exceeded.
When used in group IIC non-permissible electrostatic charges should be avoided on the
plastic housing parts. Avoid electrostatic charges that can cause electrostatic discharge
when installing or operating the device. Information on electrostatic hazards can be
found in the technical specification IEC/TS 60079-32-1.
If cable glands are required for the installation then the following points must be
observed: The cable glands must be certified in accordance with the application.
The temperature range of the cable glands must be selected according to the application. The degree of protection must not be reduced by the cable glands. Seal
the housing. Use a seal that meets the requirements of the application.
When selecting accessories, ensure that the material allows the temperature of the
enclosure to rise to up to 70 °C.
The plug connector must not be withdrawn under voltage.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)
