The input voltage is out of tolerance, input frequency is out of
tolerance, input phase failure, output voltage is out of tolerance,
output frequency is out of tolerance, output phase failure, DC
component that can occur at the output voltage, Overload that will
occur at the output (out of the periods specified), Overheating that
will cause failure related to over temperature, high voltage which
will occur at DC Bus voltage, low voltage which will occur at DC
Bus voltage, short circuit at the output.
