Retain the load within the rating of UPS to prevent faults. sockets. 6. Handle unusual events according to the trouble-shooting guide. 3. Place cables in such a way that no one can step on or trip over them. 7. Keep the UPS clean and dry. 2 3 3. 2.4 Operation SYSTEM DESCRIPTION 1. Do not disconnect the mains cable on the UPS system or the building wiring 3.1 LCD Display(Includes detachable LCD function with connecting from socket outlet during operations since this would cancel the protective remote control port to RS-232) 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. 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. Unauthorised 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. 1.

7. OPERATION MODES OF THE UPS 7.1 UPS System Block Diagram 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. 22 7.3 AC Utility Failure The AC output comes from battery, passing through DC/AC inverter and static switch within the battery backup time. 7.4 Bypass Enable Under the following conditions, the bypass will be enabled: 1.Overload. 2.Inverter failure. 3.Over-temperature 23
8. COMPUTER INTERFACE 8.2 DB9 Interface Connector 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 communicating with the computer like below. Supply RS-232 for monitoring software of UPSilon 2000 DB9 INTERFACE CONNECTOR The UPS communicates with the computer by sending out RS-232 data DB9 PIN Assignment streams to one of the serial ports. By this method the user is able to monitor the following parameters. PIN 2: RS232 RXD PIN 3: RS232 TXD Input Voltage Indicates the present input voltage to the UPS system when AC power is present. PIN 5: GND The other PINs have no function. 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. 24 25
