CHAPTER 2 • CONNECTING POWER AND SURGE 25
Note
An authorized electrical technician should perform installation and operation of this
unit. Persons other than authorized and approved electrical technicians should NOT
attempt to connect this unit to a power supply and/or traffic control cabinet, as there
is a serious risk of electrical shock through unsafe handling of the power source. Ex-
treme caution should be used when connecting this unit to an active power supply.
Wiring in AC
The first step is to get AC power into the enclosure. (Sometimes the power source is actually
DC; to see Wavetronix’s selection of DC power modules, see the Click 100–400 Series User
Guide.) If you’re using a main traffic cabinet, wire from its power source; if you’re using a
pole-mount box, the power lines or cable can be brought in through the conduit on the
bottom-left.
Note
Make sure power to AC mains is disconnected while wiring AC input.
Wiring the Click 210
The first device in the power plant, as seen in Figure 2.5, is the Click 210. This is a compact
circuit breaker DIN rail device designed to interrupt an electric current under overload
conditions. The breaker is trip-free and can be easily reset after a current interruption by
pushing the reset button.
