Installation and wiring must be carried out in accordance with the local electric laws and regulations by trained professionals.

1) Make sure that the mains wire and breakers of the building are rated for the capacity of the UPS to

prevent electric shock or risk of fire.

NOTE: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the UPS’s maximum input current. The receptacle may be damaged and destroyed.

2) Switch off the mains switch in the building before installation.

3) Turn off all the connected devices before connecting to the UPS.

4) Prepare wires based on the following table:

NOTE : The selections for color of wires should be followed by the local electrical laws and regulations.

5) Remove the terminal block cover at the rear panel of UPS. Then connect the wires according to the

following terminal block diagrams: (Connect the grounding/earthing wire first when making other wire connections. Remove the grounding/earthing wire last when connecting the UPS!)

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

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

Terminal block wiring diagram

should have leakage current protective function if necessary.

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

Warning: (Only for standard model)

● Make sure the UPS is off before the installation. The UPS should not be turned on during wiring connection.

● Do not attempt to modify the standard model into the long-run model. In particular, do not try to connect the standard internal battery to the external battery. The battery type and voltage may be different, risk of electric shock or fire may occurred!

3-5. Single UPS Operation

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

1) After power mains is connected correctly, set the breaker of the battery pack to “ON” position (this step only necessary for long-run model). Then set the line input breaker to “ON” position. At the same time the fan will start running and the UPS will start initialization. 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 directed from mains after you switch on the input breaker. In Bypass mode, the load is not protected by the UPS. To protect your precious devices, you should turn on the UPS. Refer to next step.

2) Touch “CONTROL” and select “UPS on/off” icon. It will show “Turn on UPS?” in screen and select “Yes”. Refer to On/Off UPS screen.

3) In just a few seconds, the UPS will enter into AC mode. If the mains is abnormal, the UPS will operate in Battery mode without interruption.

NOTE: When the UPS runs out battery, it will shut down automatically in Battery mode. When the mains

2. Turn on the UPS without utility power supply (in Battery mode)

is normalized, the UPS will auto restart in AC mode.

1) Make sure that the two strings of batteries are connected correctly in order of ”+,GND,-” terminals and the breaker of the battery pack is at “ON” position (only for long-run model).

2) Press the “ ” button to set up the power supply for the UPS. UPS will enter to power on mode. After initialization, UPS will enter to “No Output mode”.

3) In just a few seconds, the UPS will be turned on and enter into Battery mode.

3. Connect devices to UPS

After the UPS is turned on, you can connect devices 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 it is necessary to connect the inductive loads such as a printer, the in-rush current of the load should be calculated carefully to see if it meets the overload capability of the UPS. Any load more than 150% over designed capacity the runtime will be less than 60ms

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 to prevent overload for system safety.

5) If the overload time is over acceptable time listed in spec in AC mode, the UPS will automatically transfer to Bypass mode. After the overloading was resolved, it will return back to AC mode. If the overload time is over acceptable time listed in spec in Battery mode, the UPS will enter 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 entirely.

4. Charge the batteries

1) After the UPS is connected to the mains and turned on in AC mode, the charger will charge the batteries automatically except in battery mode, during battery self-test, overload or when battery voltage is high.

2) It’s recommended to charge batteries for at least 10 hours before operation. Otherwise, the backup time may be shorter than expected.

5. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will sound according to different battery capacity. If the battery capacity is more than 25%, the buzzer will beep once every 4 seconds. If the battery voltage drops to the alarm level, the buzzer will beep once every sec to remind users that the battery is at low level and the UPS will shut down imminently. 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 switched off, you have to prepare shutdown procedure to preserve working data or devices. Otherwise, there is a risk of data loss or load failure.

2) In Battery mode, users can touch “SETTING”  “Basic”  Audio Mute to enable “Mode Mute” to disable the buzzer.

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

4) The backup time may vary from different operating temperature and load type.

5) When setting backup time for 16.5 hours (default value from LCD menu), after discharging 16.5 hours, UPS will shut down automatically to protect the battery. This battery discharge protection can be enabled or disabled through LCD menu.

6. Test the batteries

1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, you could touch “CONTROL” and select “Battery Test”. Refer to “Battery Test” screen.

2) Users also can set battery self-test through monitoring software.

7. Turn off the UPS with utility power supply in AC mode

1) Touch “CONTROL” and select “Turn off UPS” icon to turn off the UPS. Refer to “UPS on/off” screen.

NOTE 1: If the UPS has been set to bypass output, it will bypass voltage from the mains to output

terminal even though you have turned off the UPS (inverter).

NOTE 2: After turning off the UPS, please be aware that the UPS is working in Bypass mode, there will be 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. The LCD display will turn off and UPS is now completely off.

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

1) Touch “CONTROL” and select “Turn off UPS” icon to turn off the UPS. Refer to “UPS on/off” screen.

2) Then UPS will cut off power to output terminals.

2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for details.

10. Operation in warning status

1) When LCD screen shows “Fault Mode” and the buzzer beeps once every second, it indicates that there are problems for UPS operation. Users can read the warning message(s) from “DATA LOG” menu. Please refer to the Chapter 4 for details.

2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for details.

11. Operation in Fault mode

1) When the buzzer beeps continuously, it means that there is a fatal error with the UPS. Users can get the fault code from “DATA LOG” menu. Please refer to the Chapter 4 for details.

2) Please check the loads, wiring, ventilation, mains, battery and so on after the fault occurs. Don’t try to turn on the UPS again before solving the issues. If the problems persist, contact the distributor or service personnel immediately.

3) In case of an emergency, shut off connections from mains, external battery, and output immediately to avoid possible damage to the UPS or equipment.

12. Operation in maintenance mode

This operation should only be performed by maintenance personnel or qualified technicians.

When the UPS needs to repair or service and the load could not be shut off, the UPS needs to be put into

maintenance mode.

1) First, switch off the UPS.

2) Then, remove the cover of maintenance bypass switch on the panel.

3) Turn the maintenance switch to “BPS” position.

3-6. Parallel Operation

1. Parallel system initial startup

Please make sure that all of the running UPSs are parallel models and have the same configuration.

1) Turn on each UPS in AC mode respectively (Refer to section 3-4(1)). Then, measure the inverter output voltage of each phase for each UPS with a multi-meter. Calibrate the inverter output voltage by configuring inverter voltage adjustment (Refer to SETTING  Miscellaneous screen) in LCD menu until the inverter output voltage difference of each UPS is within 1V or less.

2) Turn off each UPS (Refer to section 3-4(7.)). Then, follow the wiring procedure in section 2-4.

3) Remove the cover of parallel share current cable port on the UPS, connect each UPS one by one with the parallel cable and share current cable, and then replace the cover.

4) Turn on the parallel system in AC mode:

a) Turn on the line input breaker of each UPS. If using dual-input unit, please also turn on the

external bypass input breaker. After all UPSs enter into bypass mode, measure the output voltage between two UPSs for the same phase to make sure the phase sequence is correct. If these two voltage differences are near to zero, that means all connections are met. Otherwise, please check if the wirings are connected correctly.

b) Turn on the output breaker of each UPS. c) Turn on each UPS in turns. After a while, the UPSs should enter into AC mode synchronously

and then, the parallel system is now complete.

5) Turn on the parallel system in Battery mode:

a) Turn on the battery breaker (only available in long-run model) and external output breaker of

each UPS.

b) Turn on any UPS. A few seconds later, the UPS will enter into battery mode. c) Turn on the next UPS in sequence until all the UPSs enter into Battery mode and add to the

parallel system. Now the parallel system is now complete.

If you would like to have more information regarding the parallel operation, please contact your supplier or service center for detail parallel operation instruction.

2. Add new units into the parallel system

1) You can not add new unit into the parallel system when whole system is running. You must cut off the load and shutdown the system.

2) Make sure all of the UPS are the parallel models, and follow the wiring reference in section 2-4.

3) Install the new parallel system as per section 3-5.

3. Remove units from the parallel system

There are two methods to remove units from the parallel system:

First method:

1) Touch “CONTROL”  “Turn off UPS” and select “Yes” to turn of the UPS. Then, the UPS will enter

into Bypass mode or No Output mode without output.

2) Turn off the external output breaker of this unit, and then turn off the input breaker of this unit.

3) Turn off the battery breaker(only available in long-run model) and remove the parallel and share

current cables. And then remove the unit from the parallel system.

Second method:

1) If the bypass is abnormal, you can not remove the UPS without interruption. You must cut off the

load and shut down the system.

2) Make sure the bypass setting is enabled in each UPS and then turn off the system. All UPSs will

transfer to Bypass mode. Remove all the maintenance bypass covers and set the maintenance

switches from “UPS” to “BPS” position. Turn off all the input breakers and battery breakers in

parallel system.

3) Turn off the output breaker and remove the parallel cable and share current cable of the UPS which

you want to remove. Now, you can remove the UPS from parallel system.

4) Turn on the input breaker of the remaining UPS and the system will transfer to Bypass mode. Set

the maintenance switches from “BPS” to “UPS position and put the maintenance bypass covers back

on.

5) Turn on the remaining UPS according to the previous section.

Warning: (Only for the parallel system)

● Before turning on the parallel system to activate inverter, make sure that all unit’s maintenance

switch at the same position.

● When parallel system is turned on, please do not operate the maintenance switch of any unit.

● The parallel system DOES NOT support ECO mode. Therefore, please DO NOT “enable” ECO mode

in any unit.

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.

Only persons are adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the 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 grounding/earthing.

Batteries may cause electric shock and have a high short-circuit current. Please remove all wristwatches, rings and other conductive objects before maintenance or repair, and only use tools with insulated grips and handles for maintaining or repairing.

When replace the batteries, install the same number and same type of batteries.

Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The

batteries must be deposed according to local environmental regulations.

Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may

be toxic.

Please replace the fuse only with the same type and amperage in order to avoid fire hazards.

Do not disassemble the UPS system.
