4.4 Single-Module UPS On Bypass
If there is a major fault in the UPS it will transfer to bypass. The power flow will show green from Utility 2 to the load.
The section that had the fault will show red to draw attention to the fault. If the User shuts down the inverter without
a major fault, then the inverter will show gray and the rectifier will show green, as shown in Figure 4-2.
