Figure 2.1 – Using a Single Click 200

Note

The different cables available and how to wire them into the Click 200 will be covered
later in this section.

If you are using the two-part installation option, you’ll have an underground cable run as

part of your installation, connecting the power and comms devices in the main traffic cabi-

net to the pole-mount box and sensor. When there is an underground cable run, it is safest

practice, as well as Wavetronix standard procedure, to use two Click 200s, one on each end

of the cable: one in the main traffic cabinet and the other in the pole-mount cabinet. Both

ends of the cable should be connected to the UNPROTECTED side of their Click 200s. This

is important because the underground cable run will be susceptible to surges caused by

lightning striking the ground near it.

If this run is shorter than 600 ft. (182.9 m), you can use a Wavetronix cable; see Appendix

D for more on cable lengths.
1 Install one Click 200 device in a pole-mount cabinet on the same pole as the sensor

being protected. Install it by snapping it onto the DIN rail.

2 Connect the cable from the sensor to the PROTECTED side of this Click 200. This

cable should be kept as short as possible.

3 Install another Click 200 in the main traffic cabinet. You will likely have power and com-

munications devices in this cabinet; make sure the Click 200 is connected to them via wires

or the shared communication bus (connecting power will be covered later in this chapter;

for how to connect to communication devices, see the Click 100–400 Series User Guide).

4 Connect the pole-mount box and the main traffic cabinet by running a cable from the

UNPROTECTED side of the Click 200 in the pole-mount box to the UNPROTECTED

side of the Click 200 in the main traffic cabinet.
