4.3 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
level
grids
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
grids
will display,
display “
OVLd
”and “LINE” in turns for 2 seconds, 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 safer.
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.
4.4 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.
4.5 Discharge the batteries
1) When the UPS is in battery mode, the buzzer will beep
according to different battery level. If the battery voltage drops to
