Option 3:
After connecting N1 and L2, it becomes one high-voltage output (208/220/230/240V) at L1-N2 for 100% of the UPS rated current.
Connect load to L1-N2.
Option 4:
After connecting N1 and L2, it becomes three outputs, one high-voltage output (208/220/230/240V) at L1-N2 and two low-voltage
outputs (104/110/115/120V) at L1-N1 and L2-N2. However, there is a limit for current rating at L1-N1 and L2-N2: 25A for 6K model
and 42A at 10K model. You must connect the load taking into account such limits. Please read the notes before installation.
Connect the low-voltage load to L1-N1 and L2-N2, and connect the high-voltage load to L1-N2.
Note 1: If any load current in L1-N1 or L2-N2 is higher than 25A in 6K model and 42A in 10K model, the UPS will still operate
normally without overload warning because the total load is under the specified limit. However, the high current can damage the
isolation transformer due to overheat caused by the high current. Hence, the installation must be done with a technician to ensure
that the load current will not exceed this limitation.
Note 2: When connecting to low-voltage and high-voltage at the same time as described in option 4, the L1-N1 and L2-N2 will feed
low-voltage loads in non-isolated status because high-voltage is being generated by shorting N1-L2. If keeping a connected load in
isolated status is required, we recommend that you may only use two low-voltages at L1-N1 or L2-N2 like illustrated in option 1, and
also make sure that the total current in L1-N1 or L2-N2 does not exceed the value specified in Note1.

3-4. Single UPS Operation
1. Turn on the UPS with utility power (On grid/ AC mode)
1) After making sure that the power supply connection is correct, set the input breaker to the “ON” position first. At this point,
the fan will start running while the UPS supplies power to the load via the bypass. The UPS is now operating in Bypass mode.
Note: When the UPS is in Bypass mode, the output voltage will directly power the load from utility after you have switched on
the input breaker. In Bypass Mode, the load is not protected by the UPS. To protect your load devices, you should turn on
the UPS as explained below.
2) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
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
mode 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 (Battery mode)
1) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
2) After a few seconds, the UPS will be turned on and begin operating on “off-grid” or Battery mode.
3. Connecting devices to the UPS
After the UPS is turned on, you can connect devices to the unit.
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.

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 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 cut off immediately.
4. Charging the batteries
1) Once the UPS is connected to utility power, the unit will charge the batteries automatically, except when the USP is running
in Battery mode or while the battery self-test is in progress.
2) It is recommended to charge the batteries at least 10 hours before use to ensure proper backup time.
3) Make sure battery number setting on the control board is consistent with the actual connection.
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 the battery
has reached its lowest capacity, and that the UPS will soon shut down automatically. Shutting down non-critical loads at
this point will prolong the backup time. If the programmable timer function is enabled, the UPS will shut off programmable
output terminals automatically.
Note: There is the risk of data loss or load failure if battery runtime is exceeded.
2) To silence the buzzer sound in Battery mode, press the Mute button.
3) The backup time vary depending upon environment conditions and load types.
4) When the backup time is set at 16.5 hours (LCD panel default value), the UPS will shut down automatically to protect the
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. Testing the batteries
1) To check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode, press the Test button to initiate
the self-diagnostic tool.
2) To maintain the system reliability, the UPS will perform an automatic battery self-test on a periodic basis. The default setting
for the battery self-test is once per week.
3) Battery self-test interval can also be set through the monitoring software.
4) When the UPS is in battery self-test mode, the LCD Display and buzzer indication will be the same as in battery mode, with
the exception that the battery LED will appear blinking in this case.
7. Turn off the UPS with utility power in AC mode
1) Turn off the inverter of the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once and the UPS
will go into Bypass mode.
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 shut off the output voltage, switch off the input breaker
to the UPS. A few seconds later, there will be no display shown on the LCD panel while the UPS is now completely turned
off.
8. Turn off the UPS without utility power supply in Battery mode
1) Turn off the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once.
2) The UPS power will shut off output and there will be no indication showing on the display panel.

for all the UPS units, it will cause permanent damage to the equipment.
5. Connect both parallel cables between each UPS, the communications cable (DB-25) and the load balancing cable, as
illustrated below:
Once the above connections are completed, verfify that the following conditions are met:
1. Verify that the input voltage is the same for all UPS units (208, 220, 230 o 240V)
2. Turn on the UPS and the battery breaker located on the back panel of the UPS.
3. If the configuration is successful, the following screen will be displayed in all UPS units.
4. Verify the output voltage in Bypass mode using one enabled output breaker.
5. Next, turn the other output breaker on making sure that output is the same ouput in every UPS. The output difference among
all UPS units must not exceed 1V.
6. Once you have checked all the above, turn OFF all the UPS units and output breakers in order for this configuration to take
effect.
7. Finally, power on the UPS units to begin operation in Parallel mode.

5. Storage and maintenance
5-1. Storage
Charge the UPS for at least 7 hours before storing the unit. Cover the UPS, and place it upright in a cool, dry location. During
storage, recharge the battery in accordance with the following table:
5-2. Maintenance
The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel.
Even after the unit is disconnected from the mains, components inside the UPS system are still connected to the battery
packs which are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current is present and
no hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and the required
precautions. Keep unauthorized personnel away from batteries.
Verify that no voltage between the battery terminals and the ground is present before maintenance or repair. In this product,
the battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the
ground.
A battery can present a risk of electric shock and high short circuit current. The following precaution should be observed
when working on batteries:
•Remove watches, rings or other metal objects.
•Use tools with insulated handles.
Replace batteries with the same type and number of units.
Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The batteries must be properly
deposed according to local regulation.
Do not open or destroy batteries. Released electrolyte is highly poisonous and harmful to the skin and eyes.
Replace the fuse only with the same type and amperage in order to avoid fire hazards.
Do not disassemble the UPS system.
