ON/OFF Switch turns the inverter ON and OFF. The switch can also be used to force reset of inverter circuits by
switching it OFF, then back ON again if the Reset Pushbutton does not reset the unit. All models also feature a port
to attach a remote control (sold separately).
120 volt AC power is supplied through two North American three-prong type outlets. The outlets can accommodate
either two- or three-pin AC plugs.

HOW THESE INVERTERS WORK

Your inverter converts low voltage DC (direct current) electricity from a battery to 115 volt AC (alternating current)
household power in two stages. The first stage is a DC-to-DC conversion process that raises the low voltage DC at
the inverter input to 145 volts DC. The second stage converts the high voltage DC into 115 volts, 60 Hz AC.

Power Inverter Output Waveform

The AC output waveform of your inverter is known as a modified sine wave. It is a stepped waveform that has
characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads,
including linear and switching power supplies used in electronic equipment, transformers and small motors.
The modified sine wave produced by this inverter has an RMS (root mean square) voltage of 115 volts. Most AC
voltmeters (both digital and analog) are sensitive to the average value of the waveform rather than the RMS value.
They are calibrated for RMS voltage under the assumption that the waveform measured will be a pure sine wave.
These meters will not correctly read the RMS voltage of a modified sine wave. Non-TRUE RMS meters will read
about 20 to 30 volts low when measuring the output of this inverter. For accurate measurement of the output voltage
of this unit, use a TRUE RMS reading voltmeter such as a Fluke 87, Fluke 8080A, Beckman 4410 or Triplett 4200.

APPLIANCE POWER CONSUMPTION

Most electrical tools, appliances and electronic equipment have labels that show the unit's power consumption in
amps, watts or both. To avoid inverter shutdown and possible damage to the inverter or equipment, do not exceed
the inverter's wattage rating. To obtain a rough estimate of the current (in amperes) the power source must deliver
where the power consumption of the tool or device is given in watts AC, simply divide the power consumption of
the load by 10. For example, if a load is rated at 200 watts AC, the power source must be able to deliver: 200 divided
by 10 = 20 amperes.
Your inverter will operate most AC loads within its power rating. Some induction motors used in refrigerators,
freezers, pumps and other motor-operated equipment, require very high surge currents to start them. Your inverter
may not be able to start some of these motors even though their rated current draw is within specifications for this
power inverter.
If a motor refuses to start, observe the battery voltage using a DC voltmeter while trying to start the motor. If the
battery voltmeter drops below 11 volts while the inverter is attempting to start the motor, this may be why the motor
won't start. Make sure the battery connections are tight and the power source battery (or batteries) is (are) fully-
charged. If the connections are good and the power source is charged, but the voltage still drops below 11 volts,
you may need to use a larger power source battery (or battery combination).
Your inverter has built-in overload protection so that if you do exceed the inverter's output capacity continuously,
the unit will automatically shut down. Once the excess load is removed, the inverter can be restarted and resume
normal operation.
Note:
To restart the inverter, turn it off, and then on again. The ON/OFF Switch is located on the inverter's Front Panel (refer to
the "Control and Functions" section of this Instruction Manual).
The inverter powers resistive loads the easiest; however, larger resistive loads, such as electric stoves or heaters,
could draw more wattage than the inverter can deliver on a continuous basis.
CAUTIONS
Ensure that total continuous power consumption of all tools and appliances to be used simultaneously with your
inverter does not exceed the inverter's continuous wattage rating. Also ensure that start-up wattage for inductive
loads does not exceed peak watts for more than a second.
Appliances such as microwave ovens will normally draw more than their rated current and could possibly overload
the inverter when operated simultaneously with other appliances. For example: A 600 watt microwave oven draws
approximately 940 watts.
