5.3.3.3 Internal Fault Messages -

The inverter continually monitors several internal components. If an condition
inside the inverter occurs that does not allow proper operation, the inverter
will shut down to help protect itself. To clear these "internal" type of faults,
the inverter will require an inverter reset.
Remedy: Perform an inverter reset; see section 6-2. After resetting
the inverter, press the ON/OFF INVERTER button to turn the inverter
on and verify the fault has cleared. If the "internal" fault remains, the
inverter will require repair at an authorized service facility.
