3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connectingtopower
supply")
• Tighten the cable gland
• Whenmountinghorizontally,turnthehousingsothatthecable
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies particularly to:
• Outdoor mounting
• Installationsinareaswherehighhumidityisexpected(e.g.through
cleaning processes)
• Installations on cooled or heated vessels
3.2 Mounting instructions
During operation, the probe must not touch any installations or the
vessel wall. If necessary, fasten the probe end.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos-
sible.Theexactvalueofthemin.distance(lowerdeadband)isstated
in chapter "Technicaldata".

4 Connecting to power supply
4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing cover
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left.
3. Loosen compression nut of the cable entry gland
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

7. Check the hold of the wires in the terminals by lightly pulling on
them
8. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
9. Tighten the compression nut of the cable entry gland. The seal
ring must completely encircle the cable
10. Reinsert the display and adjustment module, if one was installed
