Basic Operation
Indicator Lights (Front Panel)
"ON" Button
• To turn the UPS ON: with the UPS plugged into a live AC wall outlet, press and hold the "ON" button for one second. Release
the button after you hear a beep. If utility power is absent, you can "cold-start" the UPS (i.e.: turn it ON and supply power for a
limited time from its batteries, if they're fully charged) by pressing and holding the "ON" button for one second until you hear a
beep.
• To perform a battery test during AC mode: press and hold the "ON" button for one second. Release the button after you hear a
beep.
• To silence the alarm during On Battery mode: press and hold the "ON" button for one second. Release the button.
"OFF/STANDBY" Button
• To turn the UPS OFF: with the UPS ON and receiving utility power, press and hold the "OFF/STANDBY" button for one second.
Then unplug the UPS from the wall outlet. The UPS will be completely OFF.*
* After you plug the UPS into a live AC outlet, the UPS will automatically charge its batteries and will supply power to its outlets unless the unit is turned OFF.
"Overload" LED: if this light is illuminated, the load is >105%. Clear the overload immediately by unplugging some of your
equipment from the outlets until the LEDs on the Load Level graph change to yellow (100% load) or green (20 to 80% load).
CAUTION! Any overload that is not immediately corrected by the user may cause the UPS to shut down and cease supplying
output power in the event of a blackout or brownout.
"Automatic Voltage Regulation" (AVR) mode LED: if the UPS is operating in AVR mode, this yellow light will be illuminated.
The UPS will boost or trim the input voltage to regulate the output voltage.
"AC mode" LED: if the input voltage is within acceptable range, this green LED will be illuminated.
"UPS Fault" LED: this red LED is illuminated when there is an internal fault in the UPS.
"Site Wiring Fault" LED: this red LED will illuminate when the UPS senses a site wiring problem.
"Battery Fault" LED: when the unit senses a weak, bad or disconnected battery, this yellow light will illuminate.
"On Battery" mode LED: if UPS is operating from battery power, this green light will be illuminated.
"Load Level" LED: During AC mode, this green light will illuminate and the LED bars will indicate the level of output load.
"Battery Capacity" LED: During battery mode or battery test mode, this green light will illuminate and the LED bars will indicate
the battery capacity.
