24 CHAPTER 2  CONNECTING POWER AND SURGE PROTECTION

Caution

An authorized electrical technician should install the preassembled backplate. Per-

sons other than authorized and approved electrical technicians should NOT attempt

to connect the backplate to a power supply and/or trac control cabinet, as there

is a serious risk of electrical shock through unsafe handling of the power source.

Extreme caution should be used when connecting the backplate to an active power

supply.

e AC power conversion section of the backplate will come pre-wired as shown in Figure

2.3. e main three components of the AC power conversion section include:

 Click 201/202/204 AC to DC converter – A Click 201 provides 1 A of power and is

capable of powering a single sensor; a Click 202 provides 2 A and can power two sen-

sors; a Click 204 provides 4 A and can power four sensors.

 Click 210 circuit breaker – Interrupts power during overload conditions and provides

a convenient way to turn power on and o for the entire system.

 Click 230 AC surge protector – Helps protect equipment from current surges on the

power lines.

Wiring Protective Earth Ground

All connections are surge protected when the protective earth ground is wired to the PE

terminal block on the backplate. Normally, the backplate should be mounted to the chassis

of the cabinet to provide a ground path. It is strongly recommended that you provide a low

impedance protective earth connection.
