6. PROTECTION FEATURES OF INVERTER
Your inverter monitors the following potentially hazardous conditions:
Low Battery Voltage
- This condition is not harmful to the inverter but could damage the
power source. An audible alarm will sound when input voltage drops to 10.5 volts. The
inverter automatically shuts down when input voltage drops to 10.0 volts. When the
condition is rectified, the unit may be restarted.
Over Voltage Protection
- The inverter will automatically shut down when the input
voltage exceeds 15 volts DC.
Short Circuit Protection
- The inverter will shut down. Remove the short circuit and inverter
will auto reset.
Overload Protection
- The inverter will automatically shut down when the continuous
draw exceeds the specified watts.
Thermal Overload Protection
- When the temperature sensor reaches 65
O
C (150
O
F),
the unit will automatically shut down. Allow the unit to cool for at least 15 minutes before
attempting to restart. Unplug unit while cooling.
Low Battery Alarm
- An alarm will sound when the voltage from the battery drops to
10.5 volts. The user should stop operation of the appliance at this time since the inverter
will shut down automatically shortly thereafter, when the battery voltage drops to 10 volts.
Start your engine to recharge the battery.
If the low voltage alarm sounds when the battery is fully charged, follow the steps for
solving lack of output power in the Troubleshooting Guide.
The alarm will sound when the inverter is overloaded, in thermal shutdown, or if there is an
excessive voltage drop between the battery and inverter.
7. COMMON PROBLEMS
“
Buzzing” sound in audio systems:
Some inexpensive stereo systems and ‘boom boxes’ emit a buzzing sound from their
speakers when operated from the inverter. This occurs because the power supply in the
electronic device does not adequately filter the modified sine wave produced by the
inverter. The only solution to this problem is to use a higher quality sound system that
incorporates a higher quality power amplified supply.
Television Interference:
The inverter is shielded to minimize interference with TV signals. However, in some instances,
some interference may still be visible, particularly with weak TV signals. Try the following
corrective measures:
-8-
•
Position the inverter as far as possible from the television, the antenna and the
antenna cables. Use an extension cable, if necessary
•
Adjust the orientation of the inverter, the antenna cables and the TV power cord
to minimize interference
•
Make sure that the antenna feeding the television provides an adequate (“snow
free) signal and that high quality, shielded antenna cable is used.
