Wire power and communication
If you are using a Click 200 surge protector with the Click 421, power and communication are provided to
the Click 421 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 421:
1 Plug a T-bus 5-screw terminal block into the first T-bus connector.
2 Wire DC power (9–28 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 421
(see labels for correct wiring).
The front of the Click 421 has one other com-
munication port.

Mount the device
The Click 421 mounts over a T-bus for power and communication:
1 If the Click 421 was shipped with the T-bus connector attached, re-
move 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 421 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.
