1. Brief introduction
1.1. System and model description
This Online Series is an uninterruptible power supply incorporating double-conversion technology. It provides perfect protection specifically for computer equipment, communication systems to computerized instruments.
Its true online double-conversion design eliminates all mains power disturbances. A rectifier converts the alternating current from the utility power to direct current. This direct current charges the batteries and powers the inverter. On the basis of this DC voltage, the inverter generates a pure sinusoidal AC voltage, which is constantly powering the loads.
Computers and Peripherals are thus powered entirely by the UPS. In the event of power failure, the maintenance-free batteries power the inverter.
This manual is applicable to the following models:
1) The 10K is a three-phase input and single-phase output long backup time model, which is able to connect with the external battery bank.

- Inspect the appearance of the UPS to see if there is any damage during transportation. Do not turn on the unit and notify the carrier and dealer immediately if there is any damage or lacking of some parts.
2.2. Input and output power cords and protective earth ground installation
- Notes for installation
- The UPS must be installed in a location with good ventilation, far away from water, inflammable gas and corrosive agents.
- Ensure the air vents on the front and rear of the UPS are not blocked. Allow at least 5m of space on each side.
- Condensation to water drops may occur if the UPS is unpacked in a very low temperature environment. In this case it is necessary to wait until the UPS is fully dried inside out before proceeding installation and use. Otherwise there are hazards of electric shock.
- Installation
Installation and wiring must be performed in accordance with the local electric code and the following instructions by professional personnel.
For safety, please cut off the mains power switch before installation. The battery breaker also needs to be cut off if it is a long backup time model (“L”model).
- Open the terminal block cover located on the rear panel of the UPS, please refer to the appearance diagram)
- For 10K, it is recommended to select the UL1015 8AWG(10mm2) wire or other insulated wire which complies with AWG Standard for the UPS input and output wirings.
- For 15K/20K, it is recommended to select the UL1015 6AWG(25mm2) wire or other insulated wire which complies with AWG Standard for the UPS input and output wirings.
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. Otherwise, the receptacle may be burned and destroyed.
- Connect the input and output wires to the corresponding input and output terminals according to the following diagram.
Note: you must make sure that the input and output wires and the input and output terminals are connected tightly
- The protective earth ground wire refers to the wire connection between the equipment which consumes electric equipment and the ground wire. The wire diameter of protective earth ground wire should be at least as above mentioned for each model and green wire or green wire with yellow ribbon wire is used.
- After having completed the installation, make sure the wiring is correct.
- Please install the leak current protective breaker at the output power distribution panel of the UPS if necessary.
- To connect the load with the UPS, please turn off all the loads first, then perform the connection and finally turn on the loads one by one.
- No matter the UPS is connected to the utility power or not, the output of the UPS may have electricity. The parts inside the unit may still have hazardous voltage after turning off the UPS. To make the UPS have no output, power off the UPS, and then disconnect the utility power supply.
- Suggest charging the batteries for 8 hours before use. After connection, turn the bypass breaker in the “ON” position, the UPS will charge the batteries automatically. You can also use the UPS immediately without charging the batteries first, but the backup time may be less than the standard value.
- If it is necessary to connect the inductance load 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 its start-up power consumption is too big when it is started.

Important notes: If the UPS is used in single mode, JPI and JP2 must be connected. If the UPS is used in parallel mode, the Jumper between JP1 and JP2 must be removed.
2.3. Operating procedure for connecting the long backup time model UPS with the external battery
2.3.1. The nominal DC voltage of external battery pack is 240VDC. Each battery pack consists of 20 pieces of 12V maintenance free batteries in series. To achieve longer backup time, it is possible to connect multi-battery packs, but the principle of “same voltage, same type” should be strictly followed.
2.3.2. The connector of the external battery cable is used to plug into the external battery socket of the UPS, the other end of the external battery cable is made of three open wires with ring terminals to connect with the external battery pack(s). The procedure of installing battery bank should be complied with strictly. Otherwise you may encounter the hazardous of electric shock.
- A DC breaker must be connected between the battery pack and the UPS. The capacity of breaker must be not less than the data specified in the general specification.
- Set the battery pack breaker in ”OFF” position and connect the 20 pieces of batteries in series.
- You must connect the external battery cable to the battery first, if you connect the cable to the UPS first, you may encounter the hazardous of electric shock. The positive pole of the battery is connected to the 10K in parallel with blue and brown wires; the negative pole of the battery is connected to the 10K in parallel with black and white wires; the green and yellow ribbon wire is connected to the ground of the battery cabinet. For 15K/20K, the connection of battery wire is the same as that of input and output wire, and a green or green and yellow ribbon wire UL1015 6AWG (25mm2) must be connected between the input protective earth terminal and the battery cabinet.
2.3.3. To complete the connection by plugging the connector of the external battery cable into the external battery socket of the UPS. Do not attempt to connect any loads to the UPS now. You should connect the input power wire to the right position first. And then set the breaker of the battery pack in the “ON” position. After that, set the bypass breaker in the “ON” position. The UPS begins to charge the battery packs at the time.

2.4. Parallel operation
2.4.1. Brief introduction of the redundancy
N+X is currently the most reliable power supply structure. N represents the minimum UPS number that the total load needs; X represents the redundant UPS number, i.e. the fault UPS number that the system can handle simultaneously. The bigger the X is, the higher reliability of the power system is. For occasions where reliability is highly depended on, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 3 UPSs can be connected in parallel to realize output power sharing and power redundancy.
2.4.2. Parallel installation
- Users need to opt a standard 25-pin communication cable, which should have 25 cores, corresponding stitches and shield, as the UPS parallel cable. The length of the parallel cable is appropriate to be less than 3 m.
- Strictly follow the stand-alone wiring requirement to perform the input wiring of each UPS.
- Connect the output wires of each UPS to an output breaker panel.
- Disconnect the Jumper on JP1 and JP2 of the terminal block first, and connect each output breaker to a main output breaker and then to the loads.
*The requirement of the output wiring is as follows:
- When the distance between the UPSs in parallel and the breaker panel is less than 20 meters, the difference between the wires of input & output of the UPSs is required to be less than 20%;
- When the distance between the UPSs in parallel and the breaker panel is greater than 20 meters, the difference between the wires of input & output of the UPSs is required to be less than 10%.
2.4.3. Operation and maintenance
- To perform the general operation, follow the stand-alone operating requirement;
- Startup: The units transfer to INV mode simultaneously as they start up sequentially in utility power mode;
Shutdown: the units shut down sequentially in INV mode. When the last one completes the shutdown action, each unit will shut down the inverter simultaneously and transfer to bypass mode.
