2. Description of Commonly Used Symbols Some or all of the following symbols may be used in this manual.
3. Introduction This On-Line series is an uninterruptible power supply incorporating double-converter technology. It provides perfect protection specifically for computer equipments, communication servers, and data centers. The double-converter principle eliminates all mains power disturbances. A rectifier converts the alternating current from the mains power to direct current. On the basis of this DC voltage, the inverter generates an AC sinusoidal voltage, which constantly supplies the loads.
Outstanding adaptability to the worst mains input condition. Extra wide input voltage, frequency range and waveform, avoid excessive dissipating limited battery energy. Internal charger could be up to 4Amps to decrease recharging time of battery. Optional external large charging current charger which is up to 12Amps could be supplied. N+X parallel redundancy to increase the reliability and flexibility. Number of parallel operating UPS is up to 4. HE mode with high efficiency ≥0.

Fig.4-6 Typical external isolating device installation 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, power off the UPS, and then cut off the mains power supply, wait the UPS shut down completely. 3) Open the terminal block cover located on the rear panel of UPS, please refer to the appearance diagram.
8) Connect other input and output wires to the corresponding input and output terminals according to the following diagram. 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. Fig. 4-7 Input and output Terminal Block wiring diagram Notes: 1) If the UPS is used in single mode, JP1 and JP2 must be connected.
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. 4.4 Operating Procedure For Connecting with The External Battery (Only for “S” model) 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.
3) Set the external battery pack breaker in “OFF” position and connect the 20 pieces of batteries in series. 4) Connect the external battery pack to the battery terminals. Check the polarity of connection is correct. 5) Set the 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. 4.5 EPO Connection 4.5.

Fig.
5.2.2 Battery mode The example of LCD display in battery mode is shown in the following diagram. Fig. 5-4 Battery mode When the UPS is running in battery mode, the buzzer beeps once every 4 seconds. 5.2.3 Bypass with output The LCD display in bypass mode with output is shown in the following diagram. The UPS does not have the backup function when it is in bypass mode. The power used by the load is supplied from the mains power via internal filter. The UPS will beep once every 2 minutes in bypass mode.
5.2.4 Bypass without output The LCD display in bypass mode without output is shown in the following diagram. Fig. 5-6 Bypass mode without output 5.2.5 HE mode (High Efficiency mode) It is also called economy mode. After the UPS is turned on, the power used by the load is supplied from the mains power via internal filter while the mains power is in normal range, so the high efficiency could be gained in the HE mode.
2) It is attention that the transfer time of UPS output from HE mode to battery mode is about 10ms. But it is still too long for some sensitive load. 5.2.6 Converter mode 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. Fig. 5-8 Converter mode 1) 2) The function could be enabled through the LCD setting or the software (Winpower, etc.).
Fig. 5-9 Warning 5.2.8 Fault When the fault occurs, it illustrates that some fatal problems happened, the UPS would directly cut off the output or transfer to bypass, and keep alarming. The backlight of LCD would also turn to red. The detailed fault table is shown in chapter of 7. Fig. 5-10 Fault 5.2.9 Other status When the UPS is overload, the alarm will beep twice every second.

6. 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 HE Function 6.1.
6.2 Converter Function 6.2.1 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. 6.2.
6.3.2 Parallel installation and operation How to install a new parallel UPS system: 1) Before installing a new parallel UPS system, user need to prepare the input and output wires, the output breaker, and the parallel cable. 2) Users need to use 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 3m.
