lightened, and then black out one by one. After a few seconds of
self-diagnoses, the UPS will be turned on to the battery mode and
output the spec voltage.
3) After the UPS is turned on to battery mode normally, both the
Inverter LED and Bypass/Battery LED will be on. The Load/Battery
level LEDs will be lightened according to the battery capacity. 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
Load/Battery level LED will indicate the load capacity in line mode.
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 indication LEDs will flash
and 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 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.
