Ensuring the degree of protection
7.4.1
Degree of protection IP66/67, Type 4X enclosure
The measuring device fulfills all the requirements for the IP66/67 degree of protection,
Type 4X enclosure.
To guarantee IP66/67 degree of protection, Type 4X enclosure, carry out the following
steps after the electrical connection:
1. Check that the housing seals are clean and fitted correctly. Dry, clean or replace the
seals if necessary.
2. Tighten all housing screws and screw covers.
3. Firmly tighten the cable glands.
4. To ensure that moisture does not enter the cable entry, route the cable so that it
loops down before the cable entry ("water trap").

5. Insert dummy plugs into unused cable entries.
7.4.2
Degree of protection IP68, Type 6P enclosure, with "Cust-
potted" option
Depending on the version, the sensor fulfills all the requirements for the IP68 degree of
protection, Type 6P enclosure and can be used as a remote version → 25.
The degree of protection of the transmitter is always only IP66/67, Type 4X enclosure and
the transmitter must therefore be treated accordingly → 51.
To guarantee IP68 degree of protection, Type 6P enclosure for the "Cust-potted" options,
carry out the following steps after the electrical connection:
1. Firmly tighten the cable glands (torque: 2 to 3.5 Nm) until there is no gap between
the bottom of the cover and the housing support surface.
2. Firmly tighten the union nut of the cable glands.
3. Pot the field housing with a potting compound.
4. Check that the housing seals are clean and fitted correctly. Dry, clean or replace the
seals if necessary.
5. Tighten all housing screws and screw covers (torque: 20 to 30 Nm).

Post-connection check
Are cables or the device undamaged (visual inspection)?
Do the cables used meet the requirements→ 38?
Do the cables have adequate strain relief?
Are all the cable glands installed, firmly tightened and leak-tight? Cable run with "water trap"
→ 51 ?
