The modified sine wave produced by our inverters has a root mean square (RMS) voltage of
110 volts. The majority of AC voltmeters are calibrated for RMS voltage and assume that the
measured waveform will be a pure sine wave. Consequently, these meters will not read the
RMS modified sine wave voltage correctly and, when measuring the inverter output, the
meters will read about 20 to 30 volts too low. To accurately measure of the output voltage of
the inverter, use a true RMS reading voltmeter such as a Fluke 87 Fluke 8060A Beckman 4410,
Triplet 4200 or any multimeter identified as "True RMS"
In Review.
z Never attempt to operate the inverter from any power source other than a
12 volt DC volt battery.
z Always disconnect the inverter when not in use.
z Always make certain the power cable terminal connections run Negative (-) to Negative (-)
and Positive (+) to Positive (+). Check these connections frequently to make sure they are
remain secure. Use the heaviest gauge wire available to connect the inverter to the power
source
.
z While connecting the inverter to the power source, make certain that the
inverter is positioned far away from any potential source of flammable
fumes or gases,
z Always ground the inverter before operating it.
z Make certain the power consumption of the appliance or equipment you
wish to operate is compatible with the capacity of the inverter. Do not
exceed 2000 watts.
z When attempting to operate battery chargers, monitor the temperature of the battery
charger for approximately 10 minutes. If the battery charger becomes abnormally warm,
disconnect it from the inverter immediately.
z When operating the inverter with an automobile or marine battery, start the engine every
30 to 60 minutes and let it run for approximately 20 minutes to recharge the battery.
z In the event of a continuous audible alarm or automatic shut down, turn the inverter OFF
immediately. Do not restart the inverter until the source of the problem has been identified
and corrected.
z To avoid battery drain, always disconnect the inverter when not in use.
z Do not expose the inverter to rain or moisture.
z Avoid placing the inverter near sources of heat or in direct sunlight.
z While in use, make sure the inverter is properly ventilated.
z Do not operate the inverter near flammable materials, fumes or gases.
