UPS, and the buzzer will beep once.
3) A few seconds later, the UPS will be turned on and enter to Battery mode.

3. Connect devices to UPS

After the UPS is turned on, you can connect devices to the UPS.
1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total load level.
2) If it is necessary to connect the inductive loads such as a printer, the in-rush current should be calculated
carefully to see if it meets the capacity of the UPS, because the power consumption of this kind of loads is
too big.
3) If the UPS is overload, the buzzer will beep twice every second.
4) When the UPS is overload, please remove some loads immediately. It is recommended to have the total loads
connected to the UPS less than 80% of its nominal power capacity to prevent overload for system safety.
5) If the overload time is over acceptable time listed in spec at AC mode, the UPS will automatically transfer to
Bypass mode. After the overload is removed, it will return to AC mode. If the overload time is over
acceptable time listed in spec at Battery mode, the UPS will become fault status. At this time, if bypass is
enabled, the UPS will power to the load via bypass. If bypass function is disabled or the input power is not
within bypass acceptable range, it will cut off output directly.

4. Charge the batteries

1) After the UPS is connected to the utility power, the charger will charge the batteries automatically except in
Battery mode or during battery self-test.
2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be shorter than
expected time.
3) Make sure the battery numbers setting on the control board (Please refer to the section 3-4-12 for detailed
setting) is consistent to real connection.

5. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the battery
capacity is more than 25%, the buzzer will beep once every 4 seconds; If the battery voltage drops to the
alarm level, the buzzer will beep quickly (once every sec) to remind users that the battery is at low level and
the UPS will shut down automatically soon. Users could switch off some non-critical loads to disable the
shutdown alarm and prolong the backup time (the UPS would cut off the programmable output terminal
automatically when the programmable timer function is enabled). If there is no more load to be switched off
at that time, you have to shut down all loads as soon as possible to protect the devices or save data.
Otherwise, there is a risk of data loss or load failure.
2) In Battery mode, if buzzer sound annoys, users can press the Mute button to disable the buzzer.
3) The backup time of the long-run model depends on the external battery capacity.
4) The backup time may vary from different environment temperature and load type.
5) When setting backup time for 16.5 hours (default value from LCD panel), after discharging 16.5 hours, UPS
will shut down automatically to protect the battery. This battery discharge protection can be enabled or
disabled through LCD panel control. (Refer to 3-7 LCD setting section)

6. Test the batteries

1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode, you
