7.6 Guaranteeing the degree of protection of the measuring device
"
Caution!
Do not loosen the threaded fasteners of the sensor housing, as otherwise the degree of
protection guaranteed by Endress+Hauser no longer applies.
To guarantee the degree of protection of the measuring device.
Perform the following steps after electrical connection:
• Check that the housing seals of the connection and electronics compartment are clean and
fitted correctly. Dry, clean or replace the seals if necessary.
• Tighten all housing screws and screw covers.
• Firmly tighten the cable glands.
• To ensure that moisture does not enter the cable entry, route the cable so that it loops down
before the cable entry ("water trap") → 29.
• Insert dummy plugs into unused cable entries.
• Notes on measuring devices with IP68 option → 16.
