Also, ensure that the antenna cable is properly shielded and of good quality. 17 OPERATION OPERATION pro1200to3000w.4/30/2010 8:55 AM Page 21 2. Change the relative positions of the inverter, antenna cables and television power cord. 3. Isolate the television, its power cord and antenna cables from the 12 volt power source by running an extension cord from the inverter to the television set. 4. Coil the television power cord and the input cables running from the 12 volt power source to the inverter. Note: Inexpensive sound systems may emit a "buzzing" sound when operated with the inverter. This is due to inadequate filters in the sound system. There is no solution to his problem short of purchasing a sound system with a higher quality power supply. For You Microwave Chefs. The power rating commonly associated with microwave ovens is the "cooking power" which is the power being "delivered" to the item being microwaved. The actual operating power requirement rating is higher than the cooking power rating and typically is referenced on the back of the microwave. If the operating power requirement does not appear on the back of the microwave, check the owner’s manual or contact the manufacturer. 18 Some Powerful Advice. When driving with the inverter in operation, make certain that neither the inverter nor the power cords will impede safe operation of your vehicle. Keep the unit and all cords clear of the steering wheel, gas, brake and clutch To maintain your inverter in proper working condition, note the following important safety precautions: • MOISTURE. Keep the inverter dry. Do not expose it to 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 sources are wet. Water and many other liquids can conduct electricity which may lead to serious injury or death. • HEAT. For peak efficiency, the ambient air temperature should be between 50° and 80° F. Avoid placing the inverter on or near heating vents, radiators or other sources of heat. Do not place the inverter in direct sunlight. • VENTILATION. In order to disperse the heat generated while the inverter is in operation, keep it well ventilated. While in use, maintain several inches of clearance around the top and sides of the inverter. • FUMES & GASES. Avoid using the inverter near flammable materials. Do not place the inverter in areas such as battery compartments, where fumes or gases may accumulate. 19 OPERATING PRINCIPALS OPERATION pro1200to3000w.4/30/2010 8:55 AM Page 23 For You Technical Types. 1. Basic Operating Principles: Whistler inverters work in two stages. During the first stage, the DC to DC converter increases the DC input voltage from the power source (e.g. a 12 volt battery) to 145 volts DC. In the second stage, the high voltage DC is converted to 110 volts (60 Hz AC) using advanced power MOSFET in a full bridge configuration. The result is excellent overload capability and the capacity to operate difficult reactive loads. The output waveform resulting from these conversions is a "quasi-sine wave" or a "modified sine wave" as shown on below. This stepped waveform is similar to the power generated by utilities and has a broad range of applications. The modified sine wave produced by the Inverter 20 The modified sine wave produced by your Whistler inverter has a root mean square (RMS) voltage of 110 volts. of AC voltmeters measure RMS voltage and assume that measured waveform will be a pure sine wave. Consequently, these meters will not read the RMS modified sine wave voltage correctly and, when measuring your Whistler inverter output, the meters will read about 20 to 30 volts too low. To accurately measure the output voltage of your inverter, use a true RMS reading voltmeter such as a Fluke 87, Fluke 8060A, Beckman 4410, Triplett 4200 or any multimeter identified as "True RMS."

Check these connections frequently to ensure that they are secure. • Make certain the rated power consumption of the appliance or equipment you wish to operate is compatible with the capacity of your inverter. • If the rated power consumption of the equipment is in the range of the maximum specified wattage of your converter, test the inverter to ensure that it will operate properly. • Before attempting to use a battery charger see page 16. • Before attempting to use medical equipment see page 6. • Use the proper gauge cable (smaller the number, the larger the cable) available to c...
