Please allow an acclimatization time of at least two hours. Do not install the UPS near water or in damp environment. Do not install the UPS where it would be exposed to direct sunlight or near heat. Do not connect appliances or items of equipment which would overload the UPS (e.g. laser printers, etc.) to the UPS output. Do not block ventilation openings in the UPS's housing. Ensure allow at least 0.5m of space on front and rear of the UPS. This UPS should be connected with TN earthing system. The power supply for this unit must be single-phase rated in according with the equipment nameplate. It also must be suitably grounded. Place cables in such a way that no one can step on or trip over them. Connect UPS with the earth reliably before connecting to the building wiring terminal, and external battery source must also be earthed. An integral single emergency switching device which prevents further supply to the load by the UPS in any mode of operation should be provided in the building wiring installation. An appropriate disconnect device as short-circuit backup protection should be provided in the building wiring installation. The equipment is powered by two sources: the mains source, the internal battery or the external battery source. With the installation of the equipment, the sum of the leakage current of the UPS and the connected load does not exceed 5% of rated value of input current. 1 ENGLISH 1.2. Operation Do not disconnect the main cable on the UPS or the building wiring terminals during operation since this would remove the protective earth from the UPS and all connected loads. The UPS output terminal block may still be electrically lived even if the UPS is not connected to the building wiring terminal, for there is internal current source (batteries). In order to fully disconnect the UPS, first turn the input breaker in the "OFF" position, then disconnect the mains lead. Indiscriminate operation of switches may cause output loss or damage to equipment. Refer to instruction before conducting any control. While the UPS work as a parallel system, the external parallel cable should be reinforced insulation. Ensure that no liquid or other foreign objects can enter the UPS. 1.3. Maintenance, Servicing and Faults Do not remove the enclosure since the UPS operates with hazardous voltages. It is to be serviced only by qualified maintenance personnel. Caution! Risk of electric shock. Even after the unit is disconnected from the mains power supply (building wiring terminal) components inside the UPS are still connected to the battery which are potentially dangerous. Before carrying out any kind of service or maintenance, isolate UPS and disconnect the batteries. Verify that no current is present and no hazardous voltage exists in the capacitor or BUS capacitor. Batteries must be replaced only by qualified personnel. Batteries have a high short-circuit current and pose a risk of shock. Take all precautionary measures specified below and any other necessary measures when working with batteries: remove all jewellery, wristwatches, rings and other metal objects use only tools with insulated grips and handles. When changing batteries, replace with the same quantity and the same type of batteries. 2 ENGLISH Do not attempt to dispose of batteries by burning them. It could cause explosion. The UPS may be connected to external battery package. Proper disposal of batteries is required. Refer to your local codes for disposal requirements. Do not open or destroy batteries.

After the device is installed, it must add a warning label with the following wording or the equivalent on the external AC contactor: RISK OF VOLTAGE BACKFEED. Isolate the UPS before operating on this circuit, then check for hazardous voltage between all terminals. L N Input Mains Breaker AC Contactor Mains Input UPS Coil Remotes Swith Fig.4-1 Typical external isolating device installation 10 ENGLISH 2) No matter the UPS is connected to the mains power or not, the output of the UPS may be electrically live. The parts inside the unit may still have hazardous voltage after turning off the UPS. To make the UPS have no output, turn off the UPS, and cut off the mains power supply, wait the UPS shut down completely, finally cut off the battery connection. 3) Open the terminal block cover located on the rear panel of UPS, please refer to the appearance diagram. 4) For 6K(L), it is recommended to select the UL1015 10AWG (6mm²) or other insulated wire which complies with AWG Standard for the UPS input and output wirings. 5) For 10K(L), it is recommended to select the UL1015 8AWG (10 mm²) or other insulated wire which complies with AWG Standard for the UPS input and output wirings. 6) Ensure the capacity of mains power supply. 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. 7) The protective earth ground wire should be installed first according to the following diagram. It is better to use green wire or green wire with yellow ribbon wire. 8) Connect other input and output wires to the corresponding input and output terminals according to the following diagram. Note: Make sure that the input and output wires and the input and output terminals are connected tightly. INPUT LN Input L Input N Input Ground OUTPUT LN Output N Output L Output Ground Fig.4-2 Input and output Terminal Block wiring diagram 11 ENGLISH 9) It is requested to use the accessorial terminal splices which can be compacted on the wires tightly, to ensure the connection between the wires and the terminal block is reliable. 10) Install an output breaker between the output terminal of UPS and the load, and the breaker should be with leakage current protective function if necessary. 11) Turn off all the loads first before connecting the load with the UPS, then perform the connection and finally turn on the loads one by one. 12) After completing the installation, please check the wires to make sure all were connected correctly and tightly. 13) Suggest charging the batteries for 8 hours before use. After Installation, turn on the mains power switch and turn the input breaker in the "ON" position, the UPS will charge the batteries automatically. It can also use the UPS immediately without charging the batteries, but the backup time may be less than the standard value. 14) 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 to make the UPS which capacity is small fail easily. 4.3. External Battery Pack Connecting Procedure 1. The nominal DC voltage of external battery pack is 192Vdc. 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. For 6KL, select the UL1015 10AWG (6mm²)respectively or other insulated wire which complies with AWG Standard for the UPS battery wirings. 3. For 10KL, select the UL1015 8AWG (10mm²)respectively or other insulated wire which complies with AWG Standard for the UPS battery wirings. 4. The external battery pack must be independent for each UPS. It is forbidden that two UPS use one external battery pack. 5. The procedure of installing battery pack should be complied with strictly. Otherwise it may encounter the hazardous of electric shock. 1) Ensure the UPS is not powered on and the mains input breaker is set in the 12 ENGLISH "OFF" position. 2) A DC breaker must be installed between the external battery pack and the UPS. The capacity of breaker must be not less than the data specified in the general specification. 3) Set the external battery pack breaker in "OFF" position and connect the 16 pieces of batteries in series. 4) Connect the external battery pack to the battery terminals. Check the polarity of connection is correct. 5) Set breaker of the battery pack in the "ON" position. 6) Set the mains input breaker in the "ON" position, the UPS would power on and start to charge the battery pack. 4.4. EPO Connection EPO(Emergency power off):when the emergency occurs, such as the failure of load, the UPS can cut off the output at once by operating the EPO port manually. The connection Normally the EPO connector is closed with a wire on the rear panel (Fig.4-4),which is supplied in the accessory. Once the connector is open, the UPS would stop the output and enter EPO status (Fig.4-3). Fig.4-3Enable the EPO status Fig.4-4 Disable the EPO status To recover to normal status, first EPO connector should be closed (Fig.4-4),and press button OFF more than 1 second to clear EPO status, then UPS would stop alarm and recover to Bypass model. And UPS needs be turned on by manual operation. 13 ENGLISH 4.5.

Special Function The series UPS has some special functions, which could satisfy some special application of user. And the functions have own features, please contact your local distributor for further information before using the function. 6.1. ECO Function Brief introduction of ECO function If ECO function is set to enable, after the UPS is turned on, the power used by the load is directly supplied from the mains power via internal filter while the utility power is in normal range, so the economy mode could be gained in ECO mode. Once the mains power is loss or abnormal, the UPS would transfer to Line mode or Battery mode and the load is supplied continuously. The great virtue is overall high efficiency96% of UPS, to save power for user. But the disadvantage is: 1) The load can't be protected as well as in Line mode, for the load is directly supplied from the mains; 2) The transfer time of UPS output from ECO mode to Battery mode is about 10ms. So the function is not suitable to some sensitive loads, and the region where the mains power is unstable. Set the function The function could be enabled through the LCD setting. 6.2. Converter Function Brief introduction of Converter function In converter mode, the UPS would free run with fixed output frequency (50Hz or 60Hz). Once the mains power is loss or abnormal, the UPS would transfer to Battery mode and the load is supplied continuously. The great virtue is the output frequency is fixed, which is required by some very sensitive loads. But the disadvantage is the load capacity of UPS should be derated to 60% in converter mode. Set the function The function could be enabled through the LCD setting. 24 ENGLISH 7.
