To conduct a simulation test:
Switch the UPS on and wait for the "AC normal" indicator to light up. Then unplug the UPS from the AC outlet to
simulate a power failure.
When the failure occurs, power is immediately supplied to your equipment from the UPS battery. The alarm will
beep once every 10 seconds, reminding you that your equipment is running on a limited power source.
During power failure, manually save and close the files you are currently working on. Then, switch the UPS off to
save the battery power for additional testing and usage. If the utility power is not restored, the alarm will change to
rapid beeps alerting the user that the UPS will soon run out of battery power and will shut itself down.
Restore utility power to connected equipment by plugging the UPS power cord back into a wall outlet.
Backup all unsaved files before you perform the power outage simulation test. If monitoring software has been
installed in the computer, then verify if the software saves the file and shut down the UPS automatically
