Disconnect all power cables if necessary. operations. The Uninterruptible Power System (UPS) is designed to meet the 2. Be careful not to damage the UPS while transporting. user‘s need of present computer, server and the equipment of office 3. Don‘t move the UPS upside down. automation that make the UPS more compact and less noisy. 4.
. SYSTEM DESCRIPTION 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 3.1 LCD Display(Includes detachable LCD function with connecting from 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.
5. Fault LED (red): To indicate the UPS is in fault condition because of inverter shutdown or over-temperature. 6. Warning LED (yellow): To indicate the UPS is in the status of overload, bypass and battery back-up. 5~9. Load & Battery Capacity LEDs: (a) No. 5 to 8 LED is green color and No. 9 (used as warning LED for overload or battery low) is yellow. 7. Normal LED (green): To indicate the UPS is operating normally.
(buzzer beeps), press this key and the On/Test/Mute key at the same 2KVA / 3KVA Tower Case time to disable the buzzer. (c) When UPS is in operation this key is pressed with the Off key simultaneously for 3 seconds, the UPS will be switched off after two beeps 13. Off key: It should be pressed with the control key (see the above item 12) simultaneously to switch off the UPS. 3.

In this screen, press on/off Control Key to enter the following steps for LO/HI voltage setting. B. The cursor (→ ) will pop up to indicate the output voltage newly selected. B.
6. TROUBLE SHOOTING GUIDE 3. LED and LCD status as below: 6.1 UPS Status and Action The description of the following guideline may be helpful in problem solving. 1. LED and LCD status as below: UPS STATUS: AC utility power is normal but UPS is overloaded. Warning LED lits up and buzzer beeps per second. UPS STATUS: AC utility power is normal. UPS is running normally, but battery ACTION: Please reduce the critical load to POWER(%)<100%. capacity is low (referring to Battery Status Menu).
5. LED and LCD status as below: 7. LED and LCD status as below: UPS STATUS: UPS STATUS: AC utility fails. The load is supplied by UPS in backup mode, and AC utility power is normal, but the load is supplied by AC utility power via bypass. Output power is more than 150% (referring to the Output Power Menu). Warning LED lits up and buzzer beeps continuously. battery power is approaching low level. Buzzer alarm beeps every second. ACTION: UPS will shut down automatically. Please save data soon.
7. OPERATION MODES OF THE UPS 7.3 AC Utility Failure The AC output comes from battery, passing through DC/AC inverter and 7.1 UPS System Block Diagram 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 7.4 Bypass Enable battery charging loop.
8.2 DB9 Interface Connector 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 communicating with the computer like below. Supply RS-232 for monitoring software of UPSilon 2000 The UPS communicates with the computer by sending out RS-232 data DB9 INTERFACE CONNECTOR DB9 PIN Assignment streams to one of the serial ports. By this method the user is able to monitor the following parameters.
