Charge the batteries
1) After the UPS is connected to the utility power, the charger will charge the batteries automati-
cally 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.
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 bat-
tery 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.
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.
2. To keep the system reliable, the UPS will perform the battery self-test automatically periodi-
cally. The default setting period is once per week.
3. Users also can set battery self-test through monitoring software.
4. If the UPS is at battery self-test, the LCD display and buzzer indication will be the same as at
Battery mode except that the battery LED is flashing.
Turn off the UPS with utility power supply in AC mode
1) Turn off the inverter of the UPS by pressing “OFF” button for at least 0.5s, and then the
buzzer will beep once. The UPS will turn into Bypass mode.
NOTE 1
: If the UPS has been set to enable the bypass output, it will bypass voltage from utility power
to output sockets and 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 input breaker. A few seconds later, there is no display shown on the display panel and
UPS is complete off.
Turn off the UPS without utility power supply in Battery mode
1. Turn off the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep
once.
2. Then UPS will cut off power to output and there is no display shown on the display panel.
Mute the buzzer
1. To mute the buzzer, please press the “Mute” button for at least 0.5s. If you press it again
after the buzzer is muted, the buzzer will beep again.
2. Some warning alarms can’t be muted unless the error is fixed.
