Connect cables
If your installation has an underground
cable run, use two Click 200 devices:
one in the pole-mount cabinet, the other
in the main traffic cabinet, as shown here.
These devices protect the sensor and the
main traffic cabinet from surges on the
underground cable run caused by lightning
striking the ground nearby.
The Click 200 uses the 8-conductor cable.
The wiring is shown below.
1
Run a cable from the sensor into the
pole-mount cabinet. Wire it into the
PROTECTED side of the Click 200.
2
Wire a second cable into the UNPRO-
TECTED side of the Click 200.
Run that cable from the pole-mount cabinet to the main traffic cabinet.
3
Wire that cable into the UNPROTECTED side of the second Click 200.
Note.
The 9-conductor cable, used with a retrofit SmartSensor HD, differs from the images below in these ways: there’s a gray
ground wire; there’s three drain wires, which can be connected to any GND terminal; the +485 wire is all white (no blue stripe).

Wire earth ground
All Click 200 devices should be mounted on a DIN rail that is connected to earth ground, either through an earth-ground
chassis or a 16 AWG or larger grounding wire attached to a 7-ft. (2.1-m) grounding rod. Follow the steps below to correctly wire
to earth ground:
1
Connect the grounding wire from either the DIN rail or a GND screw terminal on the UNPROTECTED side of the Click
200 to the lug bolt on the inside of the pole-mount box.
2
Connect another grounding wire from the exterior lug bolt to earth ground.
