Place the UPS in a well ventilated, dry, clean and stable indoors environment. Avoid vibration, dust, humidity, corrosive and flammable gases and liquids. To reduce high room temperature extractor fans should be installed. Air filters should be used to prevent from dust entering the UPS. The environment temperature around the UPS should in the range of 0~40 C. If the environment temperature exceeds 40 C, the rated load capacity should be reduced by 12% per 5 C. The max temperature should not exceed 50 C. Unpacking the UPS in a low-temperature environment may cause condensation to occur inside the UPS enclosure. To reduce the hazard of electrical shock, do not install the UPS until the inside and outside of the enclosure are absolutely dry. Batteries should be mounted in an environment where the temperature is within the required specs. Temperature is a major factor in determining battery life and capacity. In a normal installation, the battery temperature is maintained between 15 C and 25 C. Keep batteries away from heat sources or main air ventilation area, etc. Typical battery performance data are quoted for an operating temperature between 20 C and 25 C. Operating it above this range will reduce the battery life while operation below this range will reduce the battery capacity. Should the equipment not be installed immediately it must be stored in a room so as to protect it against excessive humidity and or heat sources. An unused battery must be recharged every 6 months. Temporarily connecting the UPS to a suitable AC supply and activating it for the time required to recharge the batteries. The highest altitude that UPS may work normally with a full load is 1500 meters. The load capacity should be reduced when this UPS is installed at an altitude higher than 1500 meters. Load coefficient equals max load at altitude divided by nominal power of the UPS. Altitude(m) Load coefficient 100% 95% 90% 85% 80% 75% 70% 65% Cooling of the UPS depends on the internal fan. Install the UPS in an area with good air ventilation. Do not block the ventilation holes at the front and rear of the UPS. This manual is for qualified personnel only Page 7

16 4.1 Operation Modes 4 Operation The UPS is a double-conversion on-line UPS that may operate in the following modes: Normal mode The rectifier/charger derives power from the AC Mains and supplies DC power to the inverter while floating and boosting charge the battery simultaneously. The inverter converts the DC power to AC and supplies to the load. Battery mode (Stored Energy Mode) If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the critical AC load. There is no power interruption to the critical load. The UPS will automatically return to Normal Mode when AC recovers. Bypass mode If the inverter is out of order, or if overload occurs, the static transfer switch will be activated to transfer the load from the inverter supply to bypass supply without interruption to the critical load. If the inverter output is not synchronized with the bypass AC source, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the critical AC load. This is to avoid paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than an electrical cycle e.g. less than 15ms (50Hz) or less than 13.33ms (60Hz). This manual is for qualified personnel only Page 15

17 ECO Mode When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set at ECO mode to increase the efficiency of the power supplied. In ECO mode, the UPS works in Line-interactive mode, so the UPS will transfer to bypass supply. When the AC is out of the set window, the UPS will transfer from bypass to Inverter and supplies power from the battery. The LCD shows all related information on the screen. Maintenance mode (Manual Bypass) A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS is out of order or in repair and this manual bypass switch bears for equivalent rated load. This manual is for qualified personnel only Page 16

18 4.2 Turn on/off UPS Restart procedure Make certain grounding is correct and secure. 1) Set the Battery Breaker to the ON. 2) Switch ON the power switch for standard UPS. Check to see if the load is safely connected with the output of the UPS. If the load is not ready to receive power from the UPS, make sure that it is safely isolated from the UPS output terminals. 3) Switch ON UPS input switch If the Rectifier input is within voltage range, the rectifier will start up in 30 seconds, the inverter will start up after. 4) Switch ON UPS output switch If the rectifier fails at startup, the bypass LED will light up. When the inverter starts up, the UPS will transfer from bypass mode to inverter mode, and then the bypass LED extinguishes and the inverter LED lights up. The status will be shown on the LCD display Test procedure When the UPS is operating normally it may take 60 seconds to start up the system and perform self-test completely. 1) Switch off the MAINS to simulate utility failure. The rectifier will turn off and the battery should feed the inverter without interruption. Now the of battery LEDs should be turned on. 2) Switch on the MAINS to simulate utility recovery. The rectifier will restart automatically after 20 seconds and the inverter will supply to the load. It is recommended to use Dummy loads for testing. The UPS can be loaded up to its maximum capacity during load test. This manual is for qualified personnel only Page 17
