Replace Battery
Failure of a battery self-test causes the UPS to emit short beeps for one
minute and the replace battery LED illuminates. Refer to Trouble-
shooting in this manual.
Battery
Disconnected
The replace battery LED flashes and short beep is emitted every two
seconds to indicate the battery is disconnected.
Automatic Self-Test
The UPS performs a self-test automatically when turned on, and every
two weeks thereafter (by default).
During the self-test, the UPS briefly operates the connected equipment
on battery.
If the UPS fails the self-test, the replace battery LED
lights and
immediately returns to online operation. The connected equipment is
not affected by a failed test. Recharge the battery for 24 hours and per-
form another self-test. If it fails, the battery must be replaced.
Manual Self-Test
Press and hold the button for a few seconds to initiate the self-test.
On Battery Operation
The Smart-UPS switches to battery operation automatically if the utility power fails. While running
on battery, an alarm beeps four times every 30 seconds.
Press the
button (front panel) to silence the UPS alarm (for the current alarm only). If the utility
power does not return, the UPS continues to supply power to the connected equipment until the bat-
tery is exhausted.
If PowerChute
®
is not being used you must manually save your files and turn off the computer before
the UPS fully discharges the battery.
