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 could press the "Test" button to let the UPS do
battery self-test. S creen 1.1-2.
2) Users also can set battery self-test through monitoring software.
