5.2 Connection of the sensor

After having mounted the sensor in the meas.
position according to the instructions in chap-
ter 4 "Mounting and installation", loosen the
closing screw on the top of the sensor. The
sensor cover with the optional indication
display can then be opened. Unscrew the
compression screw and shift the screw over
the approx. 10 cm dismantled connection
cable. The compression screw of the cable
entry is protected with a safety lock-in posi-
tion against automatic loosening.

Now loop the cable through the cable entry
into the sensor. Screw the compression
screw on the cable entry and clamp the dis-
mantled wires of the cable to the appropriate
terminal positions.
The terminals operate without terminal screw.
Press the white opening buckets with a small
screwdriver and insert the copper core of the
connection line into the terminal opening.
Check the position of the lines in the terminal
