1. INTRODUCTION
1.1 General Description
The continuity of electrical power is an essential requirement for critical load operations .The Uninterruptible Power System (UPS) is designed to meet the user‘s need of present computer, server and the equipment of office automation that make the UPS more compact and less noisy.
To choose the UPS as your equipment protector is a wise investment because it supplies reliable, pure and stable power at affordable price.
1.2 Key features
1. Multiple microprocessor and double-conversion design base.
2. Wide input range designed to operate under harsh environment.
3. High input power factor and DC-start function.
4. LED and LCD display for detail status and data; real-time alarm silence.
5. Enhanced protections against light, surges, and disturbance etc.
6. Remote monitoring with SNMP intelligent slot and RS-232 interface.
7. Light weight and compact size, easy to transport and place.
1.3 Important Notices
To be sure that the UPS will be operated correctly, the following items should be noticed:
2
1. Read instructions carefully before operating the UPS.
2. UPS power connect instruction should be followed.
3. Please don‘t open the case to prevent danger.
4. If the UPS will be stored for long period, the battery must be charged once every 90 days.
5. Retain the load within the rating of UPS to prevent faults.
6. Handle unusual events according to the trouble-shooting guide.
7. Keep the UPS clean and dry.
2. SAFTY INSTRUCTION
2.1 Transporting
1. Disconnect all power cables if necessary.
2. Be careful not to damage the UPS while transporting.
3. Don‘t move the UPS upside down.
4. Please transport the UPS system only in the original packaging (to protect against shock and impact).
2.2 Positioning
1. Do not put the UPS on rugged or declined surface.
2. Do not install the UPS system near water or in damp environments.
3. Do not install the UPS system where it would be exposed to direct sunlight or near heat.
3
4. Do not block off ventilation openings in the UPS system’s housing and don’t leave objects on the top of the UPS.
5. Allow a minimum distance of 10 cm in the rear and two sides of the UPS for ventilation.
6. Keep the UPS far away from heat emitting sources.
7. Do not expose it to corrosive gas.
8. Ambient temperature : 0℃ - 40℃
2.3 Installation
1. Connect the UPS system only to an earthed shockproof socket outlet.
2. Do not connect domestic appliances such as hair dryers or office equipment which would overload the UPS system (e.g. laser printers) to UPS output sockets.
3. Place cables in such a way that no one can step on or trip over them.
2.4 Operation
1. Do not disconnect the mains cable on the UPS system or the building wiring socket outlet during operations since this would cancel the protective earthing of the UPS system and of all connected loads.
2. The UPS has its own internal power source (batteries). The output terminals may be live even when the UPS is not connected to the AC supply.
3. Ensure that no fluids or other foreign objects can enter the UPS system.
4
2.5 Maintenance and Service
1. Caution - risk of electric shock.
Even after the unit is disconnected from the mains power supply (building wiring socket outlet), components inside the UPS system are still connected to the battery and are still electrically live and dangerous. Before carrying out any kind of servicing and/or maintenance, disconnect the batteries and verify that no current is present.
2. Only persons adequately familiar with batteries and with the required precautionary measures may exchange batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
3. Batteries may cause electric shock and have a high short-circuit current.
Please take the precautionary measures specified below and any other measures necessary when working with batteries:
- remove wristwatches, rings and other metal objects
- use only tools with insulated grips and handles.
4. When changing batteries, install the same number and same type of batteries.
5. Do not attempt to dispose of batteries by burning them. This could cause battery explosion.
6. Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes.

4.1 Inspection
1. The system may be installed and wired only by qualified electricians in accordance with applicable safety regulations.
2. When installing the electrical wiring, please note the nominal amperage of your incoming feeder.
3. Inspect the packaging carton and its contents for damage. Please inform the transport agency immediately should you find signs of damage. Please keep the packaging in a safe place for future use.
4. Please ensure that the incoming feeder is isolated and secured to prevent it from being switched back on again.
4.2 Connection
1. UPS Input Connection
If the UPS is connected via the power cord, please use a proper socket with protection against electric current and pay attention to the capacity of the socket.
2. UPS Output Connection

23
7. OPERATION MODES OF THE UPS
7.1 UPS System Block Diagram
7.3 AC Utility Failure
The AC output comes from battery, passing through DC/AC inverter and static switch within the battery backup time.
7.2 Normal Operation
There are two main loops when AC utility is normal: the AC loop and the battery charging loop. The AC output power comes from AC utility input and passes through AC/DC rectifier, DC/AC inverter and static switch to support power to load. The battery charging voltage comes from AC utility input and converted by AC/DC charger to support battery-charging power.
7.4 Bypass Enable
Under the following conditions, the bypass will be enabled:
1.Overload.
2.Inverter failure.
3.Over-temperature
4.DC BUS fail
24 25
8. COMPUTER INTERFACE
8.1 communication interface
The communication interface (DB9 port) on the back of the UPS may be connected to a host computer. The port provides two different modes for communicating with the computer like below.
1. Supply dry contact function (like RUPS of Megatec Company)
The port simulates relays closing to communicate with the computer. Its major functions are as follows.
(1) To broadcast a warning when power fails.
(2) To close any open files before the battery exhausted out.
(3) To turn off the UPS.
2. Supply RS-232 for monitoring software (like RUPSII or UPSilon 2000 of
Megatec Company)
The UPS communicates with the computer by sending out RS-232 data streams to one of the serial ports. By this method the user is able to monitor the following parameters.
Input Voltage
Indicates the present input voltage to the UPS system when AC power is present.
Output Voltage Indicates the present output voltage of the UPS.
AC Frequency Indicates the actual output frequency of the UPS.
Battery Voltage
Indicates the present DC voltage of the UPS battery.
Temperature Indicates the actual temperature inside the UPS.
