i
Before installing the sensors on the underground cables, disconnect the power to all the cables, depending
upon the cable mount type.
To install the single core cable ground sensor, follow the procedure:
Loosen the fixing bolt and unmount the belt from one side of the housing.
²
Keep the 3 single-core cables together in parallel as per the required end-to-end cable distance (220 mm
²
to 340 mm). Place the belt around them.
Connect the ground-sensor housing with the belt. Insert the belt up to the stopper and tighten the fixing
²
bolt.
Ensure that the cable tie is fastened only on the middle cable for firm stability and better accuracy as
²
shown in Figure 3-10. For single-core cables in vertical direction, the sensor mounting must be such that
the arrow on the sensor is always in the upwards direction for better stability.
Loosen the glands in the device and insert the electrical cable from the ground sensor. Connect the
²
sensor output cables (red and black) to the respective sensor input terminals (S1 and S2) which is
displayed on PCBA. The red color cable is to be connected to S1 terminal and black color cable to S2
terminal respectively.
