1. Safety and EMC instructions Please read carefully the following user manual and the safety instructions before installing the unit or using the unit! 1-1. Transportation and Storage Please transport the UPS system only in the original package to protect against shock and impact. The UPS must be stored in the room where it is ventilated and dry. 1-2. Preparation Condensation may occur if the UPS system is moved directly from cold to warm environment.
1-4. • Connection Warnings There is no standard backfeed protection inside, please isolate the UPS before working according to this circuit. The isolation device must be able to carry the UPS input current. • This UPS should be connected with TN earthing system. • The power supply for this unit must be single-phase rated in accordance with the equipment nameplate. It also must be suitably grounded.
1-5. Operation Do not disconnect the earth conductor cable on the UPS or the building wiring terminals in any time since this would cancel the protective earth of the UPS system and of all connected loads. The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminal blocks may be electrically live even if the UPS system is not connected to the building wiring outlet.
2. Installation and Operation There are two different types of online UPS: standard and long-run models. Please refer to the following model table. Model Type Model Type 6K 6KL Standard Long-run model model 10K 10KL Parallel function is also available for these two types and related installation and operation of Parallel function will be described in detail in the following content. 2-1.

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. 2-4. UPS Installation for Parallel System If the UPS is only available for single operation, you may skip this section to the next. 1) Install and wires the UPSs according to the section 2-3.

LCD Panel: Display Function Backup time information Indicates battery discharge time in numbers. H: hours, M: minutes, S: seconds Fault information Indicates that the warning and fault occurs. Indicates the fault codes, and the codes are listed in details in section 3-9. Mute operation Indicates that the UPS alarm is disabled. Output & Battery voltage information Indicates the output voltage, frequency or battery voltage.
Indicates the Inverter circuit is working. Indicates the output is working. Battery information Indicates the Battery capacity by 0-25%, 26-50%, 51-75%, and 76-100%. Indicates the battery is not connected. Indicates low battery level and low battery voltage. Input & Battery voltage information Indicates the input voltage or frequency or battery voltage. Vac: Input voltage, Vdc: battery voltage, Hz: input frequency 3-3.
3-4. Single UPS Operation 1. Turn on the UPS with utility power supply (in AC mode) 1) After power supply is connected correctly, set the breaker of the battery pack at “ON” position (the step only available for long-run model). Then set the input breaker at “ON” position. At this time the fan is running and the UPS supplies power to the loads via the bypass. The UPS is operating in Bypass mode.
5. Battery mode operation 1) When the UPS is in Battery mode, the buzzer will beep 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 quickly (once every sec) to remind users that the battery is at low level and the UPS will shut down automatically soon.
2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for the details. 10. Operation in warning status 1) When Fault LED flashes and the buzzer beeps once every second, it means that there are some problems for UPS operation. Users can get the fault code from LCD panel. Please check the trouble shooting table in chapter 4 for details. 2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for the details. 11.
5） Turn on each UPS in turns and make sure that AC mode LED or Battery mode LED displays in each UPS. Measure the output voltage of each UPS to check if the voltage difference is less than 2V (typical 1V) with multimeter. If the difference is more than 2V, please check that parallel cable or share current cable are connected well. If they are all connected well, maybe it’s UPS internal issue. Please contact your local distributor or service center for help.

LCD Setting There are three parameters to set up the UPS. Refer to following diagram. Parameter 1: It’s for program alternatives. There are 15 programs to set up. Refer to below table.
15 programs available list for parameter 1: Code Description Bypass AC 01 Output voltage Y 02 Output frequency Y 03 Voltage range for bypass Y 04 Frequency range for bypass Y 05 ECO mode enable/disable Y 06 Voltage range for ECO mode Y 07 ECO mode frequency range setting Y 08 Bypass mode setting Y Y 09 Battery backup time setting Y 10 Programmable output setting** 11 Battery ECO CVCF Battery Y Y Y Y Y Y Y Y Y Y Y Shutdown point for programmable output Y Y
ATO NCF: Setting UPS to normal mode (not CVCF mode). If selected, the output frequency will synchronize with the input frequency within 46~54 Hz at 50Hz or within 56~64 Hz at 60Hz according to setting in parameter 2. If 50 Hz selected in parameter 2, UPS will transfer to battery mode when input frequency is not within 46~54 Hz. If 60Hz selected in parameter 2, UPS will transfer to battery mode when input frequency is not within 56~64 Hz.
06: Voltage range for ECO mode Interface Setting Parameter 2: Low voltage point in ECO mode. The setting range is from 5% to 10% of the nominal voltage. Parameter 3: High voltage point in ECO mode. The setting range is from 5% to 10% of the nominal voltage. 07: Frequency range for ECO mode Interface Setting Parameter 2: Set low frequency point for ECO mode. 50 Hz system: Setting range is from 46.0Hz to 48.0Hz. 60 Hz system: Setting range is from 56.0Hz to 58.0Hz. The default value is 48.0Hz/58.0Hz.
10: Programmable output setting Interface Setting Parameter 3: Set programmable output. You may choose the following three options: ON: Programmable output is manually switched on timelessly. OFF: Programmable output is manually switched off. However, if UPS restarts, this setting will automatically go to “ATO” status. ATO: Programmable output is automatically turned on or cut off according to battery or load status.
14: Charger voltage adjustment Interface Setting Parameter 2: you may choose Add or Sub to adjust charger voltage Parameter 3: the voltage range is from 0V to 9.9V, the default value is 0V. NOTE: *Before making voltage adjustment, be sure to disconnect all batteries first to get the accurate charger voltage. *We strongly suggest to use the default value (0). Any modification should be suitable to battery specifications.
ECO mode Description When the input voltage is within voltage regulation range and ECO mode is enabled, UPS will bypass voltage to output for energy saving. LCD display CVCF mode Description When input frequency is within 46 to 64Hz, the UPS can be set at a constant output frequency, 50 Hz or 60 Hz. The UPS will still charge battery under this mode.
Fault status Description When UPS has fault happened, it will display fault messages in LCD panel. LCD display 3-9.
