2.5 Manual Simulation of Power Outage for the UPS
To test the backup function, you may unplug the power cord of the UPS or simply use the test function described in the
previous section. If the UPS is left to run continuously, it is a good idea to perform a periodic function test on the unit
(at least once a week). Observe that your equipment operates properly and uninterrupted during this period. Plug the
power cord back in if the function test was performed by unplugging it.
To conduct a simulation-test:
Switch the UPS on the UPS. Then unplug it from the AC outlet to simulate a utility failure.
When utility failure occurs, power is immediately supplied to your equipment from the UPS battery. The alarm will
beep once every 2 seconds and the Battery Mode icon will blink every five seconds, reminding you that your
equipment is running on a limited power source.
If the utility power is not restored, the alarm will change to 1 beep every second, alerting the user that the UPS will
soon run out of battery power and will shut itself down.
During utility failure, manually save and close the files you are currently working on and close your computer.
Then, switch the UPS off to conserve the battery power for additional testing and usage.
Restore electrical power to connected equipment by re-plugging the UPS power cord into a wall outlet.
Backup all unsaved files before you perform the power outage simulation test.

The Alarm may be turned off by pushing the “On” Switch for approximately 1 second in the Battery Mode .
Unless any other warning or fault condition occurs, the alarm remains at Silence condition once the “Alarm
Silence” is turned off.
4. Service and Maintenance
4.1 Routine Maintenance
Use dry soft cloths to clean the front panel and plastic parts.
Do not use any detergent that contains alcoholic ingredient.
The expected lifetime of the battery is around 3 years. Improper operation or harsh environment will reduce the
actual lifetime.
Unplug the UPS from power inlet if the UPS will not operate for a long period of time.
Charge the battery every 3 months to recover the self-discharge capacity when the UPS is in extended storage.
When replacing batteries, use the sealed lead-acid maintenance free battery with the same number and capacity.
Battery Replacement Overview
When the Battery Replacement icon lights up, you may leave the UPS to be re-charged for at least 8~10 hours to see
whether it turns off after Self-test Function is executed again. If the icon remains unchanged, you may unscrew the
Easy Swappable Battery cover, replace the battery then push the “On” Switch to disable the icon.
