3) After the UPS is turned on to battery mode normally, the panel will
display battery mode, and the buzzer will beep according to the
battery level.
3.4 Connect loads to UPS
After the UPS is turned on, you can switch on the loads.
1) It is recommended to switch on the load one by one. The panel will
display the load level.
2) If it is necessary to connect the inductance load such as a printer to
the UPS, the start-up power should be considered for calculating the
capacity of the UPS, because the power consumption is too big
when this kind of load is started.
3) If the UPS is overloaded, all the load level grids indicator will flash
and the warning indicator will lighten constantly. The buzzer will
beep twice every second for alarming.
4) If the UPS is overloaded, some loads must be switched off or
decreased immediately. It is recommend that the total loads
connected to the UPS had better be less than 80% of its nominal
power capacity to prevent the overload happen at the transient time,
and it will make your system more safe.
5) If the overload time is over spec in line mode, the UPS will transfer to
bypass, after the overload disappears, it will return to line mode. If
the overload time is over spec in battery mode, the UPS will cut off
the output and then shutdown according to the battery level.
3.5 Charge the batteries
1) After the UPS is connected to normal mains, the charger will work and
charge the batteries automatically in bypass mode or line mode.
2) Suggest charging the batteries for 10 hours before use. Otherwise
the backup time may be less than the standard value.
