3.3.1 Mounting the sensor
NOTE
The sensor is an optical precision instrument that should be protected against
shocks. Make sure that the distances to the wall, bottom and other installation
surroundings are sufficient. If necessary, protect the sensor from hitting with the
protective ring provided. Mount any fixing elements only on the stable metal
shaft.
NOTE
Always make sure the surface of the enclosure is not damaged by sharp-edged
objects. The enclosure of the sensor may not touch any metallic objects in order
to prevent contact corrosion.
NOTE
Do not suspend the sensor on the sensor connection cable. Risk of cable break
and water penetration at the cable gland.
