CHAPTER 20
• CLICK 223 177
˽ Two RS-485 connections, each consisting of one -485 and one +485 terminal
The front of the Click 223 has an LED that lights up to indicate the device has power and the
surge protection is working properly. If the LED is not lit, either the device has no power or
the surge protection is not working.
Installation
The Click 223 is designed for use with the SmartSensor 6-conductor cable and a Wavetronix
sensor that uses this cable, such as the SmartSensor Advance. The steps that follow in this
section are specific to this application. If you do not plan on using the 6-conductor cable,
you can skip the steps below and simply wire your power and communications by following
the labels on the screw terminals.
Which side of the Click 223 you wire into depends on your installation. If you’ve got an un-
derground cable run, you’ll put a Click 223 on each end and connect the ends of the cable to
the UNPROTECTED side of each device. If you’re connecting to a sensor as well, the sensor
cable should be connected into the side of the device marked PROTECTED.

Once you know which side of the device you need to wire into, follow the steps below to
do so:
1
Using a rocking motion, mount the Click 223 onto the DIN rail, making sure it’s on the
T-bus with the devices it’s supposed to protect.
2
Wire the cable to the frontmost pluggable screw terminal block: connect the blue wire
to the screw terminal marked -485B. Connect the blue and white–striped wire to the
screw terminal 485B. (For ease, you can remove the terminal block from the
