This manual contains the guidance of UPS and accumulator when installation and application, also includes the

guidance of problem setting and maintenance.

Ø Please read this user manual carefully before using or installing the machine. Ø This manual must be read to and conserved by a professional person. Ø This manual does not introduce the specified technologies. Ø This manual applies to L series 3/1 online UPS.

This manual provides the reference when using and guidance when alarming and working.

1.1. Applied condition

This UPS provides AC power supply, which is the basic power of your equipment. Please carefully check whether

the input and output pressure and frequency can meet the using requirements.

UPS input AC capacitor must be as requested. Otherwise the UPS will work improperly or even occur security

accident (when the UPS input is generator, generator capacity should be 3 multiple more than UPS).

1.2. Working environment

The working environment and maintain methods also influent the using age and failure rate of the UPS. Therefore,

please avoid the following working environment in long term.

Places over demand of specifications (temperature 0℃~40℃, relative humidity 30%~95%). ! Places with bare sunshine. " Places near by the heat sources. Over heat will speed up the external battery self-discharge. # Places liable to shaking and shoving. $ Places have powder, corrosive substances and combustible gas.

1.3. Safety notice

1.3.1. Generally the UPS is in connection with batteries. So that there might still be voltage in the output end even without AC input.

1.3.2. When UPS need to be moved or re-wiring, you must ensure that all UPS stop working, electricity input and batteries input is off. Otherwise, there may still be risk of electric shock in the output end.

1.3.3. To ensure the person%s safety, this series UPS must be of good grounding protection and of reliable grounding before the using.

1.3.4. Please keep the air intake and exhaust open. Poor ventilation will increase the internal temperature of the UPS and therefore short the lifetime of UPS spare parts.

1.3.5. Liquid and other objects should not be leaked into the inside UPS inside box.

1. Importance indication

1.3.6. In case of fire broken out around, please use dry powder fire extinguisher. Liquid fire extinguisher will be danger of electric shock.

1.3.7. The life time of product will decrease by the increasing of temperature. Regular replacement could guarantee UPS work normally and maintain sufficient time. Replacement the battery must be operated by authorized technologists.

1.3.8. If no use it long time, UPS must be stored in dry environment, the host (without batteries) the storage temperature range: -40 ~+70 .℃℃

1.3.9. In term of no use the UPS for long time, it is advised to charge it by AV for more than 12 hours every 3 months. To avoid any battery damage for long time no using.

1.3.10. Please do not open the battery cabinet in case that the electrolyte injury the skin and eye. If incaution the body contact the electrolyte, please wash it with plenty of water and then go to the hospital.

1.3.11. Please do not open the cabinet by yourself because there are many high voltage accumulator spare parts. Otherwise any accident arisen should at your peril.

1.3.12. Please do not disassembly any connection cable by yourself without permission.

1.3.13. Because this UPS is very big and heavy, please do not move and shake it violently. Also good ventilation is necessary.

1.3.14. Do not exhaust the dust when it is electrophorus. Do not use wet washrag to clean the dirt.

1.3.15. The battery must be replaced by professional technologist. Replaced battery should be send to special recycling agencies. Battery belongs to toxic waste.

Ø Bypass switch -- the breaker controls the bypass%s input and protect the bypass meanwhile. The breaker

cuts when bypass circuit is over current.

Ø Battery%s switch -- the breaker controls the battery%s input and protects the battery group meanwhile. The

breaker cuts when battery group is over current.

Ø Input switch -- the breaker controls the UPS%s AC output and protects the output meanwhile. The breaker

cuts when input over current or short circuit.

Ø Maintain switch -- it is used for maintain UPS with uninterruptible power, It will turn off when working

normally. Please refer to correct flow when using this swift, otherwise it will cause the failure of UPS or output cut.

The process of cut off the maintainence switch: turn on the bypass switch, meanwhile turn off the inverter by

manual, then turn off the output switch, the cut off the maintainence switch, and then turn off the rectifier switch and battery switch.

4. Brief introduction of UPS configuration

4.1. Rectifier

Convert the 3 phase%s input AC electricity into stable DC through the rectifier and charge the battery meanwhile. Its

consisted parts are as following:

Harmonic filter

Rectifier switch

phase mains

6 or 12 pulse rectifier

MCU

bus

Inverter

Batteries

Rectifier circuit

Input voltage and frequency inspection

Battery voltage and charging circuit inspection

BUS FILTER

As the above chart, controlled by input through rectifier switch, the main power was rectified to DC firstly by harmonic filter and secondly the 6 or 12 pulse rectifier. At last it was rectified to stable DC bus by harmonic again. Though measuring the input voltage and frequency and DC bus and controlling the rectifier, the commutating control circuit input stable DC to inverter and battery group. Meanwhile it starts protection when I/P wrong phase, be lack phase and over limited.

4.2. Inverter

Be consist of sampling circuit, single-chip controlling circuit, IGB driving circuit, IGBT module, inverter isolating transformer, filter inductance and protecting circuit. Microprocessor firstly produce the SPWM signal through computing the sampling signals, and meanwhile drive the IGBT module bas AC and change it into high frequency SPWM waves. Secondly it output pure sine AC through inverter isolating transformer, inverter filter. At the same time it adjust the output voltage and waves% shape via the feedback of sampling signals such as voltage, current and temperature.

4.3. Battery

Battery is consisted of the power slot (plastic crust), the cathode plate, the negative electrode, separator, electrolyte, inter-unit bridge, terminations, safety valves and other components. It is a power and chemical energy conversion devices. The working principle is, when AC is normal the charger will charge and the battery will convert the power to chemical energy which will be stored in the battery; when the AC works abnormally the battery will convert the chemical energy to power to UPS.

The UPS pattern is dual-mode transformation. When the inverter does not start it is bypass mode; after turning on the inverter it will high-speedily switch from static bypass switch to static inverter output switch. As static switch is electronic switch so there is no mechanical switching time.

4.5. Displaying and touching screen operation

4.5.1. Touching screen information

Touch-screen LCD monitors is our company%s latest invention of the UPS modules, using today's most popular and intuitive graphical operation interface. Comparing with the traditional button-LCD display modules, the touch-screen display module shows a more rich content which avoids frequent page turning. At the same time because the user can get corresponding information by directly press the button on the display screen. It is easy to use easy to get. Meanwhile touch-screen display module comes with real-time clock and memory and can be recorded 256 incidents and other information, which is more humanize.

4.5.2. Operation and introducation

Stand by screen shown in chart 1. UPS will start up in the show this standby screen. When the touch-screen interval of about four minutes not to touch, shows CPU will automatically cut off power -- touch screen backlight can be extended so the backlight life, and return to the standby interface (if UPS is in the police state, the touch screen will be Priority information shows that the police box, police information to repeal or abolish manual alarm will not be cut off before the show CPU touch screen backlight back to standby power supply interface).

4.6. L series 3/1 large screen LCD display and opteration

4.6.1 Standby interface

Standby interface see chart one. When turn on the UPS it will display the standby interface. When the LCD around 1 minute no one operation, the display CPU will automatically cut off the display back light0.so as to enlarge the lifetime of back light, meanwhile back to the standby interface (if the UPS in alarm statuts, the display will prior to display the alarm information, before the alarm information withdraw or manual withdraw the alarm the display CPU will not cut off the LCD back light and back to the standby interface).
