Attention:
* The 5000 Watt Power Inverter is fitted with a cooling fan.
* If the cooling fan is unable to maintain a cool enough temperature for safe operation, the inverter will
automatically shut down.
* If the inverter automatically shuts down or a continuous audible alarm is heard:
i. Turn the inverter rocker switch to the OFF (O).
ii. Determine the source of the problem, and resolve it before continuing to use the inverter.
Important Safety Measures
* For the most effective use, place the power inverter on a flat surface.
* Keep the inverter dry.
* Do not allow it to come into contact with rain or moisture.
* DO NOT operate the inverter if you, the inverter, the device being operated or any other surfaces that may
come in contact with any power source are wet.
Water and many other liquids can conduct electricity, which may lead to serious injury or death.
* Do not place the inverter on or near heating vents, radiators or other sources of heat.
* Do not place the inverter in direct sunlight. The ideal air temperature for operation is between 50°F (10°C)
and 80°F (27°C).
* Keep the inverter well ventilated in order to properly disperse heat generated while it is in use.
* While in use, make sure there are several inches of clearance around the top and sides of the inverter.
* Do not use the inverter near flammable materials.
* Do not place the inverter in areas such as battery compartments where fumes or gases may accumulate.
How Do Power Inverters Work?
There are two stages involved in transforming 12 volt DC (or battery) power into 110 volt AC power (household
current):
STAGE 1:
The power inverter uses a DC to DC transformer to increase the 12 volt DC input voltage from the power source
to 145 volts DC using advanced MOSFET transistors in a full bridge configuration.
STAGE 2:
The inverter then converts the 145 volts DC into 110 volts AC (household current), using advanced MOSFET
transistors in a full bridge configuration.
A "modified sine wave" waveform is generated by this conversion.
5000 Watt Power Inverter
The modified sine wave inverter has a root mean square (RMS) voltage of 110 volts, but most AC voltmeters
are calibrated to measure pure sine waves for their RMS voltage. This will result in these meters giving a
measurement 20 to 30 volts too low when measuring the inverter output. In order to measure the inverter output
voltage more accurately, use a true RMS reading voltmeter.
For Your Safety: Precautions to keep in mind before and while using your Power Inverter:
* Only connect the power inverter to a 12 volt battery.
* Do not modify the power cables in any way.
* Make sure the power cables only connect the inverter's NEGATIVE (-) terminal to the 12 volt power source's
NEGATIVE (-) terminal, and the inverter's POSITIVE (+) terminal connects to the 12 volt power source's
POSITIVE (+) terminal. Do not reverse polarity.
Check these connections frequently to make sure they remain tight.
* Make sure the inverter is not close to any potential source of flammable fumes or gases before connecting
the inverter to the power source.
* Make sure the power consumption of the appliance or equipment you want to operate is compatible with the
capacity of the inverter, i.e. does not exceed 5000 watts.
* If you are using the power inverter to operate battery charges, keep a check on the temperature of the battery
charger for about 10 minutes. If the battery charger becomes abnormally warm, disconnect it from the inverter
immediately.
* If you are powering the inverter with an automobile or marine battery, start the engine every 30 to 60 minutes
and let it run for about 20 minutes to recharge the battery.
* If you hear a continuous alarm or automatic shut down:
i. Turn the inverter OFF immediately.
ii. Do not restart the inverter until the source of the problem has been identified and corrected.
* Disconnect the inverter when not in use, in order to avoid battery drain.
* Do not allow the power inverter to come into contact with rain or moisture.
* Do not place the inverter near heat or in direct sunlight.
* While in use, make sure the inverter is adequately ventilated.
* Do not operate the inverter near flammable materials, fumes or gases.
