Electrical connection
3.2 Connection of the sensor
• Loosen the closing screw on the upper
side of the sensor.
• Open the sensor cover.
• Remove the sleeve nut of the PG and shift
the nut slightly over the connection cable.
• Remove the rubber seal from the PG and
shift the seal over the connection cable.
• Remove the outer insulation of the connec-
tion cable over a length of approx. 10 cm.
• Insert the cable through the PG into the
sensor.
• Connect the cables. Push the white tabs of
the spring terminals with a small screw-
driver and insert the copper core of the
connection cable into the terminal opening.
Check the hold of the individual wires in the
terminals by pulling lightly on them.
• Screw the sleeve nut back onto the PG and
screw it down tightly.
