Operation
Battery Mode
When the UPS is operating during a power outage, the alarm beeps once every four seconds and the +
If battery capacity becomes low while in Battery mode, the 
indicator flashes and the alarm beeps twice every two seconds. Immediately complete and save your work to prevent data loss and similar difficulties. When utility power is restored after the UPS shuts down, the UPS automatically restarts.
Standby Mode
When the UPS is turned off and remains plugged into a power outlet, the UPS is in Standby mode. The µindicator flashes and the bar graph indicators are off, indicating that power is not available from the UPS output receptacles. The battery recharges when necessary.
Sleep Mode
If the UPS is on battery for approximately five minutes and supporting a small electrical load (£ 10%), the UPS shuts down the load. After three minutes in Sleep mode, the UPS initiates a shutdown warning (two beeps every two seconds). This feature conserves battery power. To enable this feature, contact your service representative.
Turning the UPS On
After the UPS is connected to a power outlet, it conducts a
On button until you hear the UPS beep (approximately one second). The µindicator stops flashing and the bar graph indicators display the percentage of load being applied to the UPS.
Starting the UPS on Battery
NOTE Before using this feature, the UPS must have been powered by utility power at least once.
To turn on the UPS without using utility power, press and hold the On button for at least four seconds. The UPS supplies power to your equipment and goes into Battery mode.
