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.
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.
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The plug connector must not be withdrawn under voltage.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)
