2.9 V3 BDA/MU/RU SYSTEM WIRING - AC POWER ONLY (NO BBU)
In some rare cases the V3 BDA will be fed directly from a 120VAC circuit without utilizing any type of battery
backup system. For those cases, the main AC Cable provided by the installer can be fed directly into the
BDA through a knockout and connected to the AC Input. See below for wiring instructions.
• Switch both AC IN/AC OFF (POWER) and DC IN/BATT CHRG (BATTERY) to OFF (O) in the
BDA/MU/RU
• Ensure the AC Cable you are connecting is not live/hot. Make sure the Main AC Breaker is turned
OFF at the electrical box.
• Connect AC Wires to the Phoenix connector inside the BDA/MU/RU. The Phoenix connector is
removable for ease of installation.
