1. Loosen the 4 fixing screws on the housing cover.
2. Open the housing cover.
3. Route the two sensor cables of channel 1 through the slackened top union nut of the
cable entry. To ensure tight sealing, mount a sealing insert on the sensor cables
(push the cables through the slotted sealing insert).
4. Mount the screw part in the center cable entry at the top and then guide both sensor
cables through the entry. Then fit the coupling nut with the sealing insert on the
screw part and tighten. Ensure that the sensor cables are positioned in the cut-outs
provided in the screw part.
5. Connect sensor cable to channel 1 upstream.
6. Connect sensor cable to channel 1 downstream.
7. For a two-path measurement: proceed as per steps 3+4
8. Connect sensor cable to channel 2 upstream.
9. Connect sensor cable to channel 2 downstream.
10. Tighten the cable gland(s).
 This concludes the process for connecting the sensor cable(s).
