FEATURE FUNCTION
Self-Test Automatic: 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.
Manual: Press and hold the button for a few seconds to initiate the self-test.
Cold Start
208/120/230 V
models Only
When there is no utility power and the UPS is off, the cold start feature will switch
the UPS and connected equipment onto battery power, (see Troubleshooting).
Diagnostic Utility
Voltage
The UPS has a diagnostic feature that displays the utility voltage.
The UPS starts a self-test as part of this procedure. The self-test does not af-
fect the voltage display.
Press and hold the button to view the utility voltage bar graph display. After a
few seconds, this five-LED battery charge display on the right of the front
panel will show the utility input voltage.
Refer to the figure at left for the voltage reading, (values are not listed on the
UPS).
The display indicates the voltage is between the displayed value on the list and the
next higher value, (see Troubleshooting).
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.
If PowerChute is not being used, files must be manually saved and the computer must be turned off
before the UPS fully discharges the battery.
The UPS battery life differs based on usage and environment. Refer to www.apc.com for on battery
runtimes.
