CHAPTER 18 CLICK 221

Physical Features

Figure 18.2 – Diagram of the Click 221

The bottom of the Click 221 has a screw terminal block with four screw terminals—+DC,

-DC and two PE terminals—for DC power.

The back of the Click 221 features a 5-position connector that plugs into a T-bus connector

and provides power to the device. It also passes that power to all other devices on the T-bus.

A pinout diagram is provided on each individual unit as a reference in the field.

The faceplate has an LED used for monitoring the device: if the LED is on, the device has

power and the surge protection is functional.

Installation

To install and wire the Click 221:
1 Mount the Click 221 on the T-bus it is going to protect.

2 Wire power from the DC power source into the +DC and -DC terminals on the bottom

of the device.

3 Wire from one of the PE terminals to a good earth ground. If the device is in a cabinet,

there will likely be a central grounding point—such as a grounding lug—for just such

a purpose.

4 Watch the LED. If it comes on, the device has power and the surge protection is ready.
