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 briey after one second has passed. **If fully charged.
B
“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.
