Figure 11. An accessory wired to the #1 terminal. The external Power Supply provides operating power
for the accessory; the ASC2’s internal relay acts as an on/off switch to control the accessory action.
Wiring a single basic accessory
To connect a basic on/off accessory or light to your ASC2:
1. Attach one wire to the Power/A terminal on your power supply and connect it to the COMM
terminal of the ASC2.
2. Attach another wire to the Common/Ground/U terminal on the power supply and connect
to an accessory power terminal.
3. Attach a final wire to the remaining accessory power terminal and connect it to a
numbered terminal on the ASC2 (terminal 1 shown in the illustration).
Each of the two "COMM" terminals on the ASC2 is the common connection for four
relays. "COMM" does not mean "ground." The illustrations in this manual show
switching of the HOT or "A" connected to the shared COMM terminal.
