  Wire power and communication

If you are using a Click 200 surge protector with the Click 301, power and communication are provided 

to the Click 301 through the T-bus (see the Click 200 Quick-reference Guide). If you don’t have a Click 200 

surge protector, use the following steps to wire power and communication into the Click 301:

1  Plug a T-bus 5-screw terminal block into the first T-bus connector.

2  Wire DC power (10–30 V) from the power supply into the 

first screw terminal on the 5-screw terminal block; wire 

-DC into the second screw terminal.

3  Connect RS-485 communication (+485, -485 and GND) to 

either the remaining three screw terminals on the 5-screw 

terminal block or to the screw terminals in the pluggable 

screw terminal block on the top of the Click 301 (see labels 

for correct wiring).

The front of the Click 301 has two other communication ports.

  Mount the device

The Click 301 mounts over a T-bus for power and communication:

1  If the Click 301 was shipped with the T-bus connector attached, 

remove the connector from the module.

2  Snap the connector onto the DIN rail by positioning it over the rail 

with the male connector pointing to the right. Hook one arm over 

the edge of the DIN rail and press down on the other arm until it 

snaps into place.

3  Connect the T-bus connector to the rest of the T-bus by sliding 

them together until you hear them snap into place.

4  Mount the Click 301 onto the DIN rail: position it properly over the 

T-bus connector, hook the lip over the lower edge of the DIN rail, 

and use a rocking motion to snap the module into place.
