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 → 16.
The degree of protection of the transmitter is always only IP66/67, Type 4X enclosure and the
transmitter must therefore be treated accordingly → 39.
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).
7.5 Post-connection check
Are cables or the device undamaged (visual inspection)?
Do the cables comply with the requirements → 21?
Do the cables have adequate strain relief?
Are all the cable glands installed, firmly tightened and leak-tight? Cable run with "water trap" → 39 ?
Only for remote version: is the sensor connected to the right transmitter?
Check the serial number on the nameplate of the sensor and transmitter.
Does the supply voltage match the specifications on the transmitter nameplate ?
Is the terminal assignment correct ?
If supply voltage is present, do values appear on the display module?
Is the potential equalization established correctly → 35?
Are all housing covers installed and the screws tightened with the correct tightening torque?
