I.
Single/double AC inverter failure 1.8.1.3.1.2.1, 1.8.1.3.1.3.1
NOTE: AC inverter malfunctions may be transient in nature.
If the input or output of an inverter is out of tolerance, the
defective inverter will go off-line, and the other inverter will
take control of the inverter functions. If the defective inverter
can be reset, its failure is considered to be transient.
