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.
Repairs to these apparatus are not possible.
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.

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.
The connection cable must be prevented from being subjected to tension and torsional
loading.
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.
