3.6 Discharge the batteries
1) When the UPS is in battery mode, the buzzer will start beep
according to different battery level. If the battery voltage drops to
the alarming level, the buzzer will start beep rapidly (once every
sec) to remind the user that the capacity of battery is too low and
the UPS will be shutdown automatically soon. The user may
switch off some non-critical loads to avoid the shutdown
alarming and prolong the backup time. If no more non-critical
loads can be switched off at that time, it
’s better to shut down
rest loads as soon as possible to protect the important loads or
save data. Otherwise there might be a risk of data loss or
damage loads by power interrupted after batteries discharged.
2) If the user found the buzzer is noisy under battery mode, the
beep could be muted by pressing the test button for 2 seconds.
3)
The backup time may vary from different environmental
temperature and load type.
3.7 Test the batteries
1) The user may check the battery level or aging status when the
UPS is under normal mode (line mode) by pressing test button
for 2 seconds to enter battery test mode.
2) To make the system more reliable, the UPS will automatically
perform battery test on regular basis. The default period is once
per 90 days.
3) The battery test could be performed by sending command from
monitoring software through the communication port.
4) If the UPS enters the battery test mode, the buzzer will beep
once, and Line/Bypass/Inverter/Batter LEDs will be on and off
one by one, which allows the user to check the battery level in
this mode.
