3.1 Single Input

3.1.1 Online Mode_ Single Input_ Single Unit

In online mode, the main AC source supplies AC power via the Delta or non-Delta external maintenance bypass cabinet’s Input Breaker or Switch (Q1) and the UPS’s Bypass Switch (Q0) to the rectifier, and the rectifier converts the AC power to DC power and supplies the DC power to the inverter. In the meantime, the rectifier provides charging power to the batteries. After receiving the DC power, the inverter converts it into clean and stable AC power to the connected critical loads via the Delta or non-Delta external maintenance bypass cabinet’s

Output Breaker or Switch (Q4). Please refer to Figure 3-3. During online mode, the UPS’s

tri-color LED illuminates green and the text ‘On-Line’ appears in the upper right corner of the screen.
