Feature Function
Normal /Bypass
Manually switch connected equipment to bypass mode, so that utility power is
sent directly to connected equipment. Battery operation is not available while
the UPS is in bypass mode. (See Troubleshooting.)
Cold Start
This is not a normal condition.
Supply immediate battery power to the UPS and connected equipment (see
Troubleshooting). Press and hold the button to power up the UPS and
connected equipment. The UPS will emit two beeps. During the second beep,
release the button.
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.
Diagnostic Utility
Voltage
The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS
into the normal utility power.
The UPS starts a self-test as part of this procedure. The self-test does not
affect the voltage display.
Press and hold the button to view the utility voltage bar graph display.
After a few seconds the five-LED, Battery Charge display on the right of
the front panel shows 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.
On Battery Operation
The 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 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 two minutes of runtime remain the UPS emits a continuous beep. If PowerChute or the
Network Management Card is not being used, files must be manually saved and the comput er must
be properly shut down before the UPS fully discharges the battery.
The UPS battery life differs based on usage and environment.
