2.2 Power On/Off/Test/Silence Button:
The On/Off/Test/Silence Button has four functions:
1. When the UPS is off and AC power is present, press this button for more than 3
seconds to turn on the UPS. The UPS can be turned on even when AC power is
not present.
2. When the UPS is on, press this button for more than 3 seconds to turn off the
UPS and output power.
3. When the UPS is operating in “Battery” mode, you can silence the alarm by
quickly pressing the power button. (This function is disabled when the UPS has
a “LOW BATTERY” or “OVERLOAD” condition).
4. Quickly press the button while the UPS is under “AC” mode, and the UPS will
perform an automatic self-test procedure.
* “No load shut down” function: As a battery saving feature, the UPS will
automatically turn off if none of the connected equipment is operating while the
UPS is in back-up mode. Once normal utility power returns, the unit will wake up
automatically.
