28 CHAPTER 2  CONNECTING POWER AND SURGE

To wire the newly converted DC power out of the Click 201/202:

1 Connect a +DC conductor (usually a red wire) to the + screw terminal on the bottom

of the Click 201/202 (see Figure 2.7).

2 Connect a -DC conductor (usually a black wire) to either of the – screw terminals on

the bottom of the Click 201/202.

Figure 2.7 – Wiring DC Power Out of the Click 201/202

Note

Do not wire into the screw terminal marked DC OK; it provides only 20 mA and should

be used only for monitoring the power supply.

e screw terminal connectors on the top and bottom of the module are removable to sim-

plify wiring and are red-keyed, allowing the connector to plug into only one correct jack.

Connecting the Power Plant to Your Installation

Now the power plant is complete and you have reliable, safe DC power. e next step is to

get that power to the rest of the installation.

If the power plant is in a pole-mount box, this involves getting that power onto the T-bus; from

there it will power any communication devices that may be on it. It will also power the Click 200,

which will send the necessary 10–30 VDC, along with communications, to the sensor.

If the power plant is in a main trac cabinet, this also will involve getting DC from the

power plant on the T-bus; from there it will power any communication devices on that bus.

It will also power the Click 200, which will send that power, along with communications,

along the homerun cable to the Click 200 in the pole-mount box. at Click 200 will put

the power (and communications) onto the T-bus, powering any communication devices

that may be on it. It will also send the necessary 10–30 VDC, along with communications,

to the sensor.
