Figure C shows incorrectplacement for installation.Installation of smart sensor – underground application1. Arm the sensor clamping mechanism by carefullygrasping both clamping arms, pulling them apart untilthe trigger mechanism drops into place. Stops havebeen built into the clamping arms such that they canonly be opened to the point where the trigger will latch(Figure 5).2. For applications where the cable diameter is less than1”, leave the clamp pads attached to the clamp arms.On installations where the cable diameter exceeds 1”,remove the pads that are attached to each clampingarm. Removing the pads will allow the clampingmechanism to properly attach to larger diameter cables(Figure 6).3. Attach the sensor to a hotstick using the pulling eye.4. Push the sensor onto the cable below the elbow at alocation shown in Figure 3 while holding the hotstickhorizontal. The triggering mechanism will release theclamping arms and securely attach the device to the cable.ote:N Only the closed core current transformer (CT) needbe applied over the region of the cable where theconcentric neutral has been removed or double-backed (Figure 5).For installation on tape shield cable, the closed-core CTof the sensor should be placed above the location onthe cable where the tape shield has been removed ortrained back as part of the cable termination. Location ofthe sensor must be similar to Figure 2 (C or D), or Figure4 (A or B), for proper operation of the sensor as an FCI.5. Remove the hotstick.ote:N On 200 A loadbreak elbows, the preferred installationis demonstrated in Figure 4 (A), where the closedcore CT is located directly below the test point.Figure 5.
