Wiring the AppController for power
WARNING
Do not apply line voltage (mains voltage) to the controller's ports and terminals.
CAUTIONS
The AppController is powered by a Class 2 power source. Take appropriate isolation measures when
mounting it in a control panel where non-Class 2 circuits are present.
Carrier controllers can share a power supply as long as you:
Maintain the same polarity.
Use the power supply only for Carrier controllers.
To wire for power

Remove power from the power supply.
2
Pull the screw terminal connector from the controller's power terminals labeled
Gnd

Hot
.
3
Connect the transformer wires to the screw terminal connector.
NOTE
If using a grounded transformer, connect the ungrounded lead to the
Hot
terminal to avoid damaging
the transformer.
4
Apply power to the power supply.
5
Measure the voltage at the AppController’s power input terminals to verify that the voltage is within t
he
operating range of 21.6
–
26.4 Vac.
6
Insert the screw terminal connector into the AppController's power terminals.
7
Verify that the
Power
LED is on and the
Run
LED is blinking.
Addressing the AppController
You must give the AppController an address that is unique on the network. You can address the AppController
before or after you wire it for power.
