Wire power and communication
If you are using a Click 200 surge protector with the Click 512, power and communication are provided to
the Click 512 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 512:
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 512 (see labels for correct wiring).
The Click 512 has three other communication ports.

Mount the device
The Click 512 mounts over a T-bus for power and communication:
1
If the Click 512 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 512 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.
