20 CHAPTER 2 • CONNECTING POWER AND SURGE
˽ A single-part installation, with all components on the same pole. This pole holds your
sensor. Power and communications devices (most likely wireless) are in a pole-mount
box or there is a traffic cabinet at the base of the pole; either way there is no under-
ground cable run. Power comes from the pole itself or from a battery and/or solar
panels at the pole.
How you set up the devices in this chapter will vary depending on which of these installa-
tions you are using.
Connecting Lightning Surge Protection
The sensor should be connected to at least one surge protection device. The Click 200 and
equivalent devices are designed to prevent electrical surges along cables from damaging the
sensor and/or the cabinet. It is also a convenient spot to terminate the cable coming from
your sensor, as it has terminals for all the wires.
Note
If you choose not to use surge protection in your installation, please contact Wa-
vetronix Technical Services for assistance.
If you are using the one-part installation option—no underground cable run—put a Click 200
in the pole-mount box/traffic cabinet (whichever is being employed) as a termination point
for the cable from the sensor, and as a way to protect the box/cabinet. When there is no un-
derground cable run, it is safest practice, as well as Wavetronix standard procedure, to connect
the cable from the sensor in the UNPROTECTED side of the Click 200.
1 Install a Click 200 in the pole-mount cabinet/traffic cabinet by snapping it onto the
DIN rail. Your power and communications devices will most likely also be on this DIN
rail; make sure the Click 200 is connected to them via wires or the shared communica-
tion bus (connecting power will be covered later in this chapter; for how to connect to
communications devices, see the Click 100–400 Series User Guide).
2 Wire the cable from the sensor to the UNPROTECTED side of the Click 200.
