Troubleshooting
This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should
sound the buzzer to alert you prior to shutting itself down. You should immediately check the
indicators to determine the cause of the shutdown.
STANDBY
Indicates that the unit circuitry deemed it necessary to shut down.
One of the causes listed below has reached a critical level,
The optional line input is energized.
LOW VOLT
Indicates that the output voltage is below normal because:
The battery needs to be recharged,
The battery voltage adjustment potentiometer on the inverter is set incorrectly,
The battery voltage is not compatible with the inverter.
OVER VOLT
Indicates that the battery voltage is above normal because:
The charging system may be faulty,
The battery voltage adjustment potentiometer on the inverter is set incorrectly,
The battery voltage is not compatible with the inverter.
OVERTEMP
Indicates that the inverter is running too hot because:
Too much power is being drawn, turn off or unplug some devices.
The inverter is located in a poorly ventilated area.
LOW VOLT &
OVER VOLT
Indicates that the inverter output is shorted or nearly shorted because:
A short circuit exixts at the output,
The inverter is severely overloaded.
If the load exceeds the continuous rating for too long a period, the temperature sensor inside
the unit will turn off the outputs. After the unit cools sufficiently, it will automatically come
back on. If this happens frequently, remount the unit for increased airflow so it cools better.
Operation
Turn the switch on the front of the unit on to energize the outputs. The switch will glow to
indicate the presence of AC power at the receptacles.
