Inverter mode.
No output voltage. The status

ELEXTRICAL SHOCK AND ENERGY HAZARD
Do not disassemble the
serviceable parts. Attempting to service the unit yourself could
result in an electrical shock or burn.
Failure to follow these instructions can result in death or serious
injury.
Possible Cause
You are using a voltmeter
that cannot accurately
read the RMS voltage of a
modified sine wave.
AC shore power is not available or out of operating range and the
inverter has shut down with the display screen showing one of the
following error codes:
• Low input voltage
(fault code E01)
• High input voltage
(fault code E02)
• Unit overload or AC
output short circuit
(fault code E03)
• Thermal shutdown
(fault code E04)
• AC transfer relay has
overheated (during
shore power mode).

Solution
Use a true RMS reading voltmeter such as
the Fluke 87.
• Check the DC connections and the
cable.
• Recharge the battery.
• Verify the unit is connected to a 12V
battery.
• Check the voltage regulation of the
external charging system (if any).
• Reduce the load. Make sure the load
does not exceed the output rating.
• Allow the unit to cool off.
• Reduce the load if continuous
operation is required.
• Improve ventilation. Make sure the
inverter's ventilation openings are not
blocked.
• Improve ventilation. Make sure the
inverter's ventilation grille is not
blocked.
• Reduce the load.
