1. MOUNTING
3. Slip the rubber bushing (supplied) onto the sensor cable at the location shown below. Attach
the cable to the connector. Make a loop in the cable to prevent cable fatigue.
4. Tighten the cable clamp and close the cable cover.
5. Orient the sensor so the bow mark (on the underside of the narrower end) on its underside is
facing the bow. Fasten the sensor to the platform with hex. bolts, spring washers and flat
washers. Use M10x25 bolts if the thickness of the platform is less than 5 mm. For greater
thickness use M10x30 bolts. The torque for the hex. bolts should be 20±2Nm.
Note: For the sensor cable passed through the mounting pipe, fill the gap between the pipe
and the cable with silicone sealant, for waterproofing.
6. Coat exposed parts of bolts and wash-
ers with silicone sealant.
7. If you have the optional "bird-repellent
fixtures", attach them to the sensor sim-
ilar to as shown in the figure below. (You
may change the pattern as desired.)
8. Fix the sensor cable to the pipe at suit-
able intervals with the cable ties (sup-
plied).
