1. Tighten the lock screw under the housing cover.
2. Unscrew the housing cover.
3. If available, pull out the LCD display carefully.
4. Strip the sensor connection cable as shown and attach
wire end sleeves.
A line length of 190 mm should be ensured between the
cable gland entry and the terminals. 140 mm should be
stripped from the cable jacket along this length.
5. Guide the sensor connection cable through the cable
glands and into the housing. Then tighten the cable
glands.
6. Connect the wires as per the connection diagram.
7. If there is one, carefully insert the LCD display in the
previous / required position.
8. Screw the housing cover back on.
