Note:
If the UPS shuts down in battery mode automatically, it will
resume to line mode automatically when the mains power is
recovered.
3.4 Connect loads to UPS
After turning the UPS on, the loads can be switched on, and it is
recommended to switch on the loads one by one.
1) If it is necessary to connect the inductive load such as a printer
to the UPS, the start-up power should be considered for
determining the capacity of the UPS because the power
consumption for inductive load during start-up could be large.
2) If the UPS is overloaded, the buzzer will beep twice every
second as warning.
3) If the UPS is overloaded, some loads must be switched off or
decreased immediately. It is recommended that the total loads
connected to the UPS be less than 80% of UPS
’s nominal output
power rating to prevent the overloading during transient time and
make the system more satiable.
4) If the overloading time is too long in line mode, the UPS will
transfer to bypass mode. After the overloading disappeared, it
will return to line mode. If the overloading time is too long in
battery mode, the UPS will cut off the output and then shutdown
according battery level
3.5 Charge the batteries
1) When the UPS is connected to normal mains, the charger will start
to work and charge the batteries automatically.
2) It is suggested to charge the batteries for 10 hours at least
before the UPS performs battery mode. Otherwise the backup
time may be less than the expected value.
