The voltage supply and signal output are connected via the springloaded 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.
Connection procedure
Proceed as follows:
1. Unscrew the housing lid
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 gland and remove blind
plug
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
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

6. Insert the wire ends into the terminals according to the wiring plan
Note:
Solid cores as well as exible cores with wire end sleeves are inserted directly into the terminal openings. In case of exible cores without
end sleeves, press the terminal from above with a small screwdriver,
the terminal opening is then free. When the screwdriver is released,
the terminal closes again.
7. Check the hold of the wires in the terminals by lightly pulling on
them
