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. The
inverter filters the DC power and converts it into pure and stable AC power to the load.
