CHAPTER 27
• CLICK 340/341/342
meaning that power and communications will have to be wired in. Follow the steps below
to install and wire a Click 340, 341 or 342:
1
Attach the device to a location on the DIN rail.
2
Attach a wire for +DC (red is standard) to the screw terminal marked US1.
3
Attach a wire for -DC (black is standard) to the screw terminal marked GND.
4
Attach the other end of these two wires to a DC power source. In a traffic installation
with other Click modules, the best way to do this is to attach a female 5-screw terminal
block to the end of the T-bus and wire the +DC and -DC from step 2 into the top two
terminal connectors.
5
Make sure the DIN rail is properly grounded, as the devices are grounded via a foot
that connects with the DIN rail.
