System Connection Overlook

NOTE 1: Make sure that the wires are connected tightly with the terminals.

NOTE 2: Please install the output breaker between the output terminal and the load, and the breaker

should be qualified with leakage current protective function if necessary.

6) Put the terminal block cover back to the rear panel of the UPS.

Warning:

● For standard battery pack, there are one DC breaker to disconnect the battery pack and the UPS. But for other external battery pack, make sure a DC breaker or other protection device between UPS and external battery pack is installed. If not, please install it carefully. Switch off the battery breaker before installation.

NOTE: Set the battery pack breaker in “OFF” position and then install the battery pack.

● Pay highly attention to the rated battery voltage marked on the rear panel. If you want to change the

numbers of the battery pack, please make sure you modify the setting simultaneously. The connection with wrong battery voltage may cause permanent damage of the UPS. Make sure the voltage of the battery pack is correct.

● Pay highly attention to the polarity marking on external battery connector and make sure the correct battery polarity is connected. Wrong connection may cause permanent damage of the UPS.

● Make sure the protective earth ground wiring is correct. The wire current spec, color, position,

connection and conductance reliability should be checked carefully.

● Make sure the utility input & output wiring is correct. The wire current spec, color, position, connection and conductance reliability should be checked carefully. Make sure the L/N site is correct, not reverse and short-circuited.

2-6. Output Configuration

The UPS’s output should be connected to the input of ISO bank and the output of ISO bank is the final

output of system.

The UPS’s output connect to the input of ISO bank

★ Option 1:

The output of ISO bank

There are 2 sets of low-voltage outputs (104/110/115/120V) on L1-N1 & L2-N2. Each set is able to provide 50% of UPS rating power. Connect one load to L1-N1 and the other load to L2-N2.

★ Option 2:

The output of ISO bank

After connecting L1&L2 and N1&N2, it becomes one low-voltage output (104/110/115/120V) at L1-N1 for 100% of UPS rating power. Connect load to L1-N1 or L2-N2.

★ Option 3:

The output of ISO bank

After connecting N1 and L2, it becomes one high-voltage output (208/220/230/240V) at L1-N2 for 100% of UPS rating power. Connect load to L1-N2.

★ Option 4:

The output of ISO bank

After connecting N1&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 & L2-N2. However, there is a limit for current rating at L1-N1 & L2-N2: 25A for 6K(L) model and 42A at 10K(L) model. You must connect the load under the limitation. Please read Note first before installation.

Connect low-voltage load to L1-N1 and L2-N2, and connect high-voltage load to L1-N2.

NOTE 1: If any load current in L1-N1 or L2-N2 is higher than 25A in 6K(L) model and 42A in 10K(L) model, the UPS will still operate normally without overload warning because the total load is under the specification. However, the isolation transformer will be damaged with overheat due to high current. Hence, the installation must be done with technician and make sure that the load current does not exceed this limitation.

NOTE 2: When connecting to low-voltage and high-voltage at the same time like option 4, it will cause the L1-N1 & L2-N2 with low-voltage loads in Non-Isolated status because high-voltage is generated by shorting N1-L2. If it’s required to keep connected load in isolated status, we recommend that you may only use two low-voltages at L1-N1 or L2-N2 like option 1, and also make sure that the total current in L1-N1 or L2-N2 does not exceed the value on Note 1.

2-7. Parallel UPS Installation

For parallel UPS installation, please contact your dealer for more professional support.

3. Operations

3-1. Operating Mode/Status Description

Mode/Status

Description

UPS Power On

When UPS is powered on, it will enter into this mode for a few seconds for initializing the CPU and system.

AC Mode

When the input voltage is within acceptable range, and the UPS is turned on (the inverter is running), the UPS will provide pure and stable sine wave AC voltage. The UPS will also charge the battery in AC mode.

ECO Mode

When the input voltage is within voltage regulation range and ECO mode is enabled, the UPS will bypass voltage to output for energy saving. If the input voltage is out of the regulation range but it is still within acceptable range of AC mode, the UPS will transfer to inverter supplying the power to load (similar as AC mode).

Converter Mode

When input frequency is within 46 to 64Hz, the UPS can be set with a constant output frequency (50 Hz or 60 Hz) through the inverter. The UPS will still charge battery at this mode. There is no bypass at this mode.

Battery Mode

When the input voltage is out of the acceptable range or power failure, and the UPS is turned on (the inverter is running), the UPS will backup power from battery.

Bypass Mode

When input voltage is within acceptable range and bypass is enabled, and the UPS (inverter) is not turned on or the inverter can’t support the load, the UPS will supply power to the load through bypass.

Battery Test Mode

When the UPS is in AC mode or Converter mode, and the battery test command is enabled through LCD or monitoring software, the UPS will start Battery Test. This operation is used to check the battery status.

Warning Status

If some errors occur in the UPS (but it is still running normally), buzzer will alarm and warning code will appear in the LCD for trouble shooting.

Fault Mode

When fatal error occurs in the UPS, it will beep continuously and go to fault mode. It will display fault codes in LCD.

3-2. Button Operation

There are 4 buttons on front panel.

*If pressing UP and DOWN button together, the LCD display will rotate 90ºautomatically, this operation is used when configuring the UPS to Rack type or Tower type.

3) A few seconds later, the UPS will enter into Line mode; “Line mode” will be displayed on LCD. (In

line mode, if the utility power is abnormal, the UPS will transfer to Battery mode without interruption.)

3-5-2. Turn on the UPS without utility power supply (to Battery mode)

1) Make sure the battery is connected well and the battery pack breaker is at “ON” position;

2) Press the “ON/ENTER” button to start up the internal power, the UPS will enter into bypass mode without output;

3) When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn

4) A few seconds later, the UPS will enter into Battery mode; “Battery mode” will be displayed on LCD (In Battery mode, it will shutdown automatically when battery is depleted. If the utility power is restored, it will auto restart to Line mode.)

3-5-3. Connect devices to UPS

After the UPS is turned on, you can connect devices (load) to the UPS.

1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total load level;

2) If inductive loads needed to be connected, such as a printer, the in-rush current should be calculated carefully to see if capacity of the UPS can cover due to the huge starting power consumption of this kind of load;

3) If the UPS is overload, the buzzer will beep twice every second;

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 for system safety;

5) If the overload time is over duration listed in spec at Line mode, the UPS will automatically transfer to Bypass mode. After the overload is removed, it will return to Line mode. If the overload time is over duration listed in spec at Battery mode, the UPS will become fault status. 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.

3-5-4. Charge the batteries

1) After the UPS is connected to the utility power, the charger will charge the batteries automatically except in Battery mode or during battery test;

2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be shorter than expected;

3) Make sure the battery numbers setting on the control board (Please refer to the section of changing battery quantity) is consistent with actual connection.

3-5-5. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. Normally, the buzzer will beep once every 4 seconds in battery mode, but when the battery voltage drops to the alarm level, the buzzer will beep once per second and the UPS will shut down automatically soon. Users could switch off some non-critical loads to disable the shutdown alarm and prolong the backup time. If there is no more load to be taken off at that time, you have to shut

down all loads as soon as possible to protect the devices or save data. Otherwise, there is a risk of data loss or load failure;

2) In Battery mode, if buzzer sounds annoying, you could enter ”Control->Mute” on LCD to silence it. Please refer to the section of “LCD operation”;

3) The backup time of the long-run model depends on the external battery capacity;

4) The backup time may change under different environment temperature and load type;

5) The maximum backup time is limited by default 16.5 hours (After discharging 16.5 hours, UPS will shut down automatically to protect the battery). The time could be modified through LCD panel or communication port.

3-5-6. Test the batteries

1) If you need to check the battery status or performance when the UPS is running in Line / Converter

/ ECO mode, you could enter ”Control->Batt Test” to instruct the UPS to do battery test. Please refer to the section of “LCD operation”;

2) Users also can set battery test through monitoring software;

3) If the UPS is in battery testing, “Battery test mode” will be displayed on LCD, the buzzer indication will be the same as Battery mode, but both line LED and battery LED will be lit.

3-5-7. Turn off the UPS with utility power supply in Line mode

bypass mode with beeping once. You could also enter the “control menu” to select the instruction “Turn Off” to turn off the UPS. Please refer to the section of “LCD operation”;

NOTE: Here, “Turn Off” means that UPS is not working on line / converter / ECO / battery / battery

test mode. So even though the UPS is turned off, if input or bypass voltage is normal, the internal power supply will be still working; and if bypass status has been set to “enable”, the output voltage of the UPS will be still exist;

2) If you need to fully cut off the output, please switch off the external input breaker. A few seconds

later, there is no display shown on the panel and UPS is completely off.

3-5-8. Turn off the UPS without utility power supply in Battery mode
