Figure 27. Connecting sensor cable to terminal blocks
Now wire the sensor cable (the homerun cable coming from the
5
pole-mount box): follow the instructions in step 4 to land each
conductor into the correct terminal block. The blocks are col-
or-coded for your convenience: land the red conductor into the
block with the red label, and so on.
Make sure the backplate is connected to earth ground.

More information about this setup
Following this section provides everything your sensor needs:
The Click power plant, consisting of a circuit breaker, AC surge
˿
protector, and AC to DC converter, located in the traffic cabinet.
Two Click 200 modules, which are lightning surge protectors,
˿
one at either end of the underground cable run. This protects
all the equipment, especially the sensor, from power surges on
the cable, such as those caused when lightning hits the ground
near where it's buried, which makes these very important! It's
also where you can plug in to communicate with and configure
the sensor.
There are no communication options in this setup besides the RS-
232 and RS-485 on the Click 200. An additional communication
device can be easily added to communicate with the installation
remotely.
