3-4. Single UPS Operation

1. Switch on the UPS with utility power supply (in AC mode)

1) Once the power supply has been correctly connected, set the breaker of the battery pack to the
"ON" position (step only available for long-run model). Then set the input breaker to the "ON"
position. The fan is now running and the UPS supplies power to the loads via the bypass. The
UPS is operating in Bypass mode.
NOTE 1: When the UPS is in Bypass mode, the output voltage will be directly supplied by the utility
power after you switch on the input breaker. In Bypass mode, the load is not protected by the UPS.
To protect your valuable devices, you should switch on the UPS. Refer to next step.
Press and hold the "ON" button for 0.5s to switch on the UPS and the buzzer will beep once.
2)
3) A few seconds later, the UPS will switch to AC mode. If the utility power is unusual, the UPS will
operate in Battery mode without interruption.
NOTE 2: If the UPS is shut down in Battery mode automatically and the utility power is restored, the
UPS will start over and switch to AC mode automatically. When the UPS is running in battery, it will shut
down automatically in Battery mode. When the utility power is restored, the UPS will auto restart.

2. Connect devices to UPS

After the UPS is switched on, you can connect devices to the UPS.
1) Switch on the UPS first and then switch on the devices one by one, the LCD panel will display the
total load level.
2) If it is necessary to connect inductive loads such as a printer, the in-rush current should be
calculated carefully to see if it meets the capacity of the UPS, as the power consumption of this
kind of load may be too big.
3) If the UPS is in overload, the buzzer will beep twice every second.
4) If the UPS is in overload, please remove some loads immediately. It is recommended to have the
total loads connected to the UPS totaling less than 80% of its nominal power capacity to prevent
overloads for system safety.
5) If the overload time is over the acceptable time listed in the specs in AC mode, the UPS will
automatically switch to Bypass mode. After the overload is removed, it will return to AC mode. If
the overload time is over the acceptable time listed in spec in Battery mode, the UPS will display
the fault status. Then if the Bypass is enabled, the UPS will supply power to the load through
bypass. If the bypass function is disabled or the input power is not within the acceptable bypass
range, the output will be cut off directly.

3. Charge the batteries

1) Once the UPS has been connected to the utility power, the charger will charge the batteries
automatically except in Battery mode or during the battery self-test.
2) Charging batteries for at least 10 hours before use is recommended. Otherwise, the backup time
may be shorter than expected.
3) Make sure the battery numbers setting on the control panel (Please refer to the section 3-4-12 for
detailed settings) complies with the actual connection.
4) The charging current can be changed from 0.5A to 6A through the LCD panel or the sowftare.
Please make sure that the charging current meets the batteries requirements.
