“ON/OFF/TEST” Button
To turn the UPS on: Press and hold the ON/OFF/TEST Button
for one second.* If utility power is absent, pressing the button
will “cold-start” the UPS, i.e. turn it on and supply power from
its batteries.**
To turn the UPS off: Press and hold the ON/OFF/TEST switch
for one second.* The UPS will be turned completely off
(deactivated).
To run a Self-Test: With your UPS plugged in and turned ON,
press and hold the ON/OFF/TEST button for three seconds.**
CAUTION! To perform a self-test, you must hold the ON/
OFF/TEST button continuously for three seconds; if you
release the button too early, you will turn the UPS system
OFF and cut power to connected equipment loads. To
ensure you hold the button for the correct length of time, do
not release the button until you hear the UPS System’s
audible alarm beep twice. The first beep occurs after one
second and indicates that the UPS will turn OFF if the
button is released. The second beep occurs after three
seconds and indicates that the UPS will perform a self-test if
the button is released.
The test will last approximately 10 seconds as the UPS switches
to battery to test its load capacity and charge. All LEDs will be
lit and the UPS alarm will sound. See LED descriptions below
to determine the results of the Self-Test.
Note: You can leave connected equipment on during a self-test.
CAUTION! Do not unplug your UPS to test its batteries.
This will remove safe electrical grounding and may
introduce a damaging surge into your network connections.
* The alarm will beep once briefly after one second has passed.
** If fully charged.
Note: UPS system will function properly upon initial startup;
however, maximum runtime for the unit’s battery will only be
accessible after it has been charged for 24 hours.
“ON/OFF” LED: this green LED lights continuously to
indicate that the UPS is ON and supplying your equipment with
AC power either from a utility source or from the UPS’s
internal batteries. If the UPS’s alarm is sounding (4 short beeps
followed by a pause), the UPS is operating from its internal
batteries.
