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 or overload or battery high voltage.
2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be
shorter than expected.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will sound 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. 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, users can touch “SETTING”
“Basic”
Audio Mute to enable “Mode Mute” 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 backup time is displayed as 16.5 hours (default value), after discharging 16.5 hours, UPS will
shut down automatically to protect the battery.
6. Test the batteries
1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, you could
touch “CONTROL” and select “Battery Test”. Refer to “Battery Test” screen.
2) Users also can set battery self-test through monitoring software.
7. Turn off the UPS with utility power supply in AC mode
1) Touch “CONTROL” and select “On/Off UPS” icon. It will show “Turn off UPS?” in screen and select
“Yes”. Refer to “On/Off UPS” screen.
NOTE 1:
If the UPS has been set to bypass output, it will bypass voltage from the utility power to
output terminal even though you have turned off the UPS (inverter).
NOTE 2:
After turning off the UPS, please be aware that the UPS is working at Bypass mode and
there is risk of power loss for connected devices.
2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch off
the line input breaker and switch off the bypass line breaker. A few seconds later, there is no display
shown on the display panel and UPS is complete off.
8. Turn off the UPS without utility power supply in Battery mode
1) Touch “CONTROL” and select “On/Off UPS” icon. It will show “Turn off UPS?” in screen and select
“Yes”. Refer to “On/Off UPS” screen.
2) Then UPS will cut off power to output terminals.
9. Mute the buzzer
1) Touch “SETTING” and select “BASIC” item. There are two events available to mute. Refer to
“SETTING” screen.
2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for
details.
10. Operation in warning status
1) When warning code flashes and the buzzer beeps once every second, it means that a warning
event occurs on UPS. Users can read the warning message(s) from “DATA LOG” menu. Please refer
to the Section 3-2-6 for details.
