Protective Features
The inverter monitors the following conditions:
Low Battery Voltage: : This condition is not harmful to the inverter, but could damage the power source, so the
inverter will automatically shut down when input voltage drops below 10.5 ± 0.3 volts DC.
Input Voltage Too High : : The inverter will automatically shut down when DC input voltage exceeds 15.5 ± 0.3
volts, as this can harm the unit.
Thermal Shutdown Protection: The inverter will automatically shut down when the unit becomes overheated.
Overload/Short Circuit Protection: The inverter will automatically shut down when a short circuit occurs.
Operating Tips
The inverter should only be operated in locations that are:
D D R R Y Y : : Do not allow water or other liquids to come into contact with the inverter.
C C O O O O L L : : Surrounding air temperature should ideally be 10-20°C (50-68°F). Keep the inverter away from direct
sunlight, when possible.
W W E E L L L L - - V V E E N N T T I I L L A A T T E E D D : : Keep the area surrounding the inverter clear to ensure free air circulation around the unit.
Do not place items on or over the inverter during operation. The unit will shut down if the internal temperature
gets too hot. The inverter will auto-reset after it cools down.
S S A A F F E E : : Do not use the inverter near flammable materials or in any locations that may accumulate flammable fumes or
gases. This is an electrical appliance that can briefly spark when electrical connections are made or broken.
I I M M P P O O R R T T A A N N T T : : During engine cracking the voltage will drop below 10.5V and therefore shutdown the inverter. To
reset the unit, switch the unit OFF, leave for a few seconds and switch it ON once the engine has started.


1. Ideal storage temperature range is 0-40°C (32-104°F).
2. Store and use the BDI750 in a cool, dry place with adequate ventilation for all-around air circulation.
3. Avoid locations that are exposed to heating units, radiators, direct sunlight, or excessive humidity or
Fuse Replacement
This inverter is equipped with multiple internal fuses. Normally, these fuses will not "blow" unless there is a
serious problem inside the unit. Internal fuses are replaceable; however, only trained personnel should attempt
fuse replacement. If the unit is damaged during fuse replacement, the warranty may be voided.


Common Audio/Visual Problems
Problem: Buzzing Sound In Audio Systems
Some inexpensive stereo systems and boom boxes make a buzzing sound when operated from the inverter,
because the power supply in the electronic device does not properly filter the modified sine wave produced by
the inverter. The only solution to this problem is to use a sound system that has a higher quality power supply.
Problem: Television Interference
is shielded to minimize interference with TV signals. However, in some instances, some
interference may still be visible, especially when the TV signal is weak. Try the following to improve the picture:
1. Move the Inverter as far away as possible from the TV set, the antenna, and the antenna cables. Use a short
AC extension cord, if necessary.
2. Adjust the orientation of the antenna cables, and the TV power cord to minimize interference.
3. Make sure that the antenna feeding the TV provides an adequate (snow-free) signal and that high quality,
shielded antenna cable is used.
Fault LED Lights
The red Fault LED indicates inverter shutdown from an over-load and the yellow Fault LED indicates an input
fault and also indicates over temperature fault. See the "Protective Features" and "Common Power Output
Problems" sections.
