24 CHAPTER 2 • CONNECTING POWER AND SURGE
1 Connect the grounding wire from either the DIN rail or a GND screw terminal on the UN-
PROTECTED side of the Click 200 to the lug bolt on the inside of the pole-mount cabinet.
2 Connect another grounding wire from the exterior lug bolt to earth ground (see Figure 2.4).

Installing the Power Plant
Provide power to your installation using the Click power plant. This set of modules includes
the following:
˽ Click 201/202 AC to DC converter
˽ Click 210 circuit breaker and switch
˽ Click 230 AC surge module
A Click 201 provides 1 A of power and is capable of powering a single sensor, while a Click
202 provides 2 A and can power two sensors. (There is also a Click 204 which provides 4 A
of power, but that will usually not be necessary in an installation such as the one outlined
below.) The Click 230 helps limit current surges on the power lines; the Click 210 interrupts
power during overload conditions and provides a convenient way to turn power on and off.
The power plant will either be in a pole-mount box or in a main traffic cabinet. If it’s in a
traffic cabinet, the power will be sent to the pole via an underground cable run. How to in-
stall the power plant and then wire to a Click 200 will be covered in the rest of this section.
It should be noted that if you have ordered a Wavetronix preassembled cabinet, all of this
wiring and installation will already be done.
