On Battery Operation
The UPS switches to battery operation automatically if the utility power fails. While running On Bat-
tery, an alarm beeps four times every 30 seconds.
Press the
button to silence this alarm. If the utility power does not return, the UPS continues to
supply power to the connected equipment until the battery is fully discharged.
When 2 minutes of run time remain, the UPS emits a continuous beeping. If PowerChute is not being
used, files must be manually saved and the computer must be turned off before the UPS fully dis-
charges the battery.
Refer to www.apc.com for information on battery runtimes. The UPS battery runtime differs based on
usage and environment.
Bypass The Bypass LED illuminates indicating that the UPS is in bypass mode.
Utility power is sent directly to connected equipment during bypass mode
operation. Bypass mode operation is the result of an internal UPS fault, an
overload condition, or a user initiated command through an accessory. Bat-
tery operation is not available while the UPS is in bypass mode.
Fault The UPS detects an internal fault.
Overload The connected equipment is drawing more than the UPS power rating
allows.
Replace Battery/Bat-
tery Disconnected The battery is disconnected or must be replaced.
