POWER SOURcE
6.
Your average automobile or marine battery at full charge will provide an ample power
supply to the inverter for approximately 3 hours when the engine is off. The actual
length of time the inverter will function depends on the age and condition of the
battery and the power demand being placed by the device being operated with
the inverter.
If you decide to use the inverter while the engine is off, we recommend you turn OFF
the device plugged into the inverter before starting the engine. To maintain battery
power, start the engine every 2 to 3 hours and let it run for approximately 10 minutes
to recharge the battery.
Although it is not necessary to disconnect the inverter when turning over the engine,
it may briefly cease to operate as the battery voltage decreases. While the inverter
draws very low amperage when not in use, it should be unplugged to avoid
battery drain.
LED DISPLAY
7.
The LED display identifies the current status of the inverter.
vOLTS IN: The voltage of the vehicle’s battery, Portable Power jump starter or DC
power source.
vOLTS OUT: The voltage supplied to the device through the AC receptacle.
OUTPUT WATTAgE: The power or wattage supplied to the device plugged into
the inverter.
An audio alarm will sound when any of the following codes display. To stop the
alarm, press the ON/OFF switch:
•
– The inverter is not functional. See warranty and call Customer Service
1-800-732-7764 (Hours: 7:00 am to 5:00 pm CST).
•
– The vehicle’s battery voltage is more than 15.5-volts. The inverter will
automatically restart after the voltage drops below 15.0-volts.
•
– The continuous load demand from the device exceeds the inverter’s
wattage output.
•
– The inverter is overheated and automatically turns off for a period
of 1 to 3 minutes to cool. Make sure the inverter is well ventilated. It will
automatically restart after it cools.
•
– The vehicle’s battery voltage is less than 10.5-volts.
•
– Short circuit, power surge or overload in the device.
