Feature Function
Normal/Bypass
Manual bypass enables the user to manually put connected equipment into bypass
mode. While in bypass mode the utility power bypasses the UPS and goes directly
to the connected equipment. Battery operation is not available while the UPS is in
bypass mode. Refer to Troubleshooting in this manual.
Cold Start
This is not a normal condition.
When there is no utility power and the UPS is off, 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.

PERATION
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 run time remain the UPS emits a continuous beeping. If PowerChute software
or the Network Management card are 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

for on battery
runtimes.
