3-5. Single UPS operation
1. Turn on the UPS with utility power (in AC mode)
1) After making sure the power mains connection is done correctly, set the breaker of the battery pack to its ON
position. Then set the line input breaker to its ON position. At this point, the fan will start running while the UPS is
being initialized. In just a few seconds, the UPS will supply power to the loads via the Bypass mode.
NOTE: When UPS is in Bypass mode, the output voltage will be supplied directly from the mains 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 turn on the UPS. Refer to the next step.
2) Touch CONTROL and select the UPS on/off icon. When Turn on UPS? appears on the screen, select Yes. Refer to
the On/Off UPS screen.
3) After a few seconds, the UPS will enter into the AC mode. In case of abnormal utility power, the UPS will transfer to
battery operation to provide uninterrupted power to the outlets.
NOTE: In battery mode, the UPS will shut down automatically when the remaining charge is low. Once the utility
power is restored, the UPS will restart automatically in AC mode.
2. Turn on the UPS without utility power (in Battery mode)
1) Make sure that the two strings of batteries are properly wired with the positive, GND, and negative terminals connected
in this order, and that the breaker of the battery pack is inits ON position (applies when using external battery banks).
2) Press the POWER button to set up the power supply for the UPS. The unit will enter into the power on mode.
Once the initialization is complete, the UPS will enter into the “No Output mode”.
3) After a few seconds, the UPS will be turned on and begin operating in Battery mode.
3. Connect devices to the UPS
Once powered on, proceed to connect devices to the UPS.
1) Turn on the UPS first and then start switching “on” one load at a time, only after all of them have been plugged into
the unit. The total load level will be displayed on the LCD panel.
2) Should you need to connect inductive loads, such as a monitor or a laser printer to the UPS, the start-up power
should be used for calculating the capacity of the UPS, as energy consumption increases during initial power on. Any
load over 150% of its capacity will have a runtime less than 60ms.
3) If the UPS is overloaded, the buzzer will beep twice every second.
4) In the event of an overload, all unnecessary loads must be removed one by one, to lower the total loads connected
to the UPS to less than 80% of its nominal power capacity to prevent an overload condition.
5) If the overload time exceeds the time specified in AC mode, the UPS will automatically transfer to Bypass mode. After
the overload is removed, the UPS will return to AC mode. If the overload time exceeds the time specified in Battery
mode, the UPS will transfer to fault status. At this time, if bypass is enabled, the UPS will supply power to the loads
using the bypass mode. If the bypass function is disabled or the input power is not within the bypass acceptable
range, the output power will be immediately cut off.
4. Charge the batteries
1) Once the UPS is connected to utility power and turned on in AC mode, the unit will charge the batteries automatically,
except when running in Battery mode, while the battery self-test is in progress, during an overloaded or under high
voltage conditions.
2) It is recommended to charge the batteries at least 10 hours before use to ensure proper backup time.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to the battery capacity.
a. If the battery capacity is more than 25%, the buzzer will beep once every 4 seconds.
b. If the battery voltage drops to the alarm triggering level, the buzzer will beep once every second to indicate that it
has reached its lowest capacity, and that the UPS will soon shut down.
c. Prepare the shutdown procedure to preserve your data or devices. Otherwise, there is the risk of data loss or load
failure if battery runtime is exceeded.
2) In Battery mode, go to SETTING →Basic →Audio Mute to enable the Mute Mode and silence the buzzer.
3) The backup time varies depending upon environment conditions and load types. If using an external battery bank,
the backup time will depend on the capacity of the batteries.
4) When the backup time is set at 16.5 hours (LCD panel default value), the UPS will shut down automatically to
protectthe battery after the discharging period of 16.5 hours is completed. This battery discharge protection can be
enabled or disabled using the LCD panel control.
6.Test the batteries
1) To check the battery status when the UPS is running in AC mode/CVCF mode, press Control followed by Battery
test to initiate the self-diagnostic tool. Refer to Battery Test screen.
2) Battery self-test can also be programmed through the monitoring software.
7.Turn off the UPS with utility power supply in AC mode
1) To power off the UPS, touch CONTROL followed by the Turn off UPS icon. Refer to the UPS on/off screen.
NOTE 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utility power to the output
terminal even though the UPS (inverter) has been turned off.
NOTE 2: After turning off the UPS, please beware that the UPS is operating in Bypass mode and there is a risk of
power loss for connected devices.
2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch off the line input
breaker. A few seconds later, there will be no display shown on the LCD panel to indicate that the UPS has been shut
down completely.
8.Turn off the UPS without utility power supply in Battery mode
1) To power off the UPS, touch CONTROL followed by the Turn off UPS icon. Refer to the UPS on/off screen.
2) Then UPS will cut off power to output terminals.
9.Mute the buzzer
1) Touch SETTING and then select BASIC on the menu. There are two events available to mute. Refer to the SETTING
screen.
2) Some warning alarms cannot be muted unless the error that triggered them is fixed. Refer to section 3-4 for details.
10. Operation in warning status
1) When the Fault LED flashes and the buzzer beeps once every second, it means that the UPS is experiencing operation
issues. Fault codes are available in the DATA LOG menu. Refer to the Section 3-3-6 for details.
2) Some warning alarms cannot be muted unless the error that triggered them is fixed. Refer to section 3-4 for details.
