  • Page 14 3-1-3. Bypass Mode Upon connecting to utility input power, the UPS is in Bypass mode before UPS is turned on (if BYPASS enable setting is Enabled), and charger function will be active when battery is present. After UPS has been turned on, if the UPS encounters abnormal situations (over-temperature, overload …, etc.), UPS will perform the load from the inverter to the bypass source with no interruption.
  • Page 15 Battery Mode Diagram 3-1-6. Battery Test Mode Users can manually operate UPS to battery test mode. There is no interruption in power to the load. If the test is completed or battery fails, the UPS will return to Line mode or CVCF mode (if CVCF mode is enabled). In battery test mode, the rectifier derives power from the battery and supplies DC power to the inverter.
  • Page 16 3-1-8. CVCF Mode The CVCF mode is enabled through the LCD setting menu. The output frequency will be fixed at 50Hz or 60Hz according to setting of “Freq”. In CVCF mode, the rectifier derives power from the utility power, supplies DC power to the inverter and the charger charges the battery.
