  Wire power

Unlike many other Click devices, the Click 330 does not mount over the T-bus, meaning that power and 

communications will have to be wired in into the device’s six screw 

terminals. The first four screw terminals, marked US1, GND, US2 and 

GND, are for wiring power. (The other two, which are labeled R1 and 

R2, are for security and functionality alarm purposes.)

1  Attach the device to a location on the DIN rail that is not over a 

T-bus.

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 first screw termi-

nal marked GND.

4  Attach the other ends of these two wires to a DC power source.

Note. US2 and the second GND are for wiring in a redundant power 

supply, if you’d like to use one.

  Mount the device

The Click 330 mounts on a DIN rail. To mount, simply hook the lip over the lower edge of the DIN rail, and 

use a rocking motion to snap the module into place.

Note. Do not mount over the T-bus.
