Return of AC Power Battery Mode When the UPS is operating during a power outage, the indicator illuminates solid. The necessary energy is provided by the battery. When the utility power returns, the UPS transfers to Online mode operation while the battery recharges. If battery capacity becomes low while on Battery mode, the audible alarm beeps once every 3 seconds. This warning is approximate, and the actual time to shutdown may vary significantly. Shutdown all applications on the connected equipment because automatic UPS shutdown is imminent. When utility power is restored after the UPS shuts down, the UPS automatically restarts. Low-Battery Warning • The indicator illuminates solid. • The audio alarm beeps every three seconds. The remaining battery power is low.
