NOTE:
When the UPS is running out battery, it will shut down automatically at Battery mode.
When the utility power is restored, the UPS will auto restart in AC mode.
4.6.2 Turn on the UPS without utility power supply
4.6.2.1 Make sure that the breaker of the battery bank is at “ON” position.
4.6.2.2 Press and hold the button for 2s to turn on the UPS, and the buzzer will beep
once.
4.6.2.3 A few seconds later, the UPS will be turned on and enter to Battery mode.
4.6.3 Connect devices to UPS
After the UPS is turned on, you can connect devices to the UPS.
4.6.3.1 Switch on the devices one by one and it will display total load level in LCD panel.
4.6.3.2 If it is necessary to connect the inductive loads such as a printer, the in-rush current should be
calculated carefully to see if it meets the capacity of the UPS, because the power consumption of this
kind of loads is too big.
4.6.3.3 If the UPS is overload, the buzzer will beep every second.
4.6.3.4 When the UPS is overload, please remove some loads immediately. It is recommended to have
the total loads connected to the UPS less than 80% of its nominal power capacity to prevent overload
for system safety.
4.6.3.5 If the overload time is over acceptable time listed in spec at AC mode, the UPS will
automatically transfer to Bypass mode. After the overload is removed, it will return to AC mode. If the
overload occurs 3 times in half hour, the UPS will be locked in Bypass mode. UPS can transfer to Line
mode only by manual restart. At this time, if bypass is enabled, the UPS will power to the load via
bypass. If bypass function is disabled or the input power is not within bypass acceptable range, it will
cut off output directly.
4.6.4 Charge the batteries
4.6.4.1 After the UPS is connected to the utility power, the charger will charge the batteries
