(500W divided by 10V = 50A). 3. Conclusion: The reserve power of the battery is sufficient to satisfy the continuous load demand placed on the inverter for a maximum of about one hour. (49.8 Ah divided by 50A = 1 hour). Note: • When the inverter will be operating equipment or appliances with high continuous load ratings for extended periods, it is not advisable to power the inverter with the same battery used to power your vehicle. If the car or truck battery is utilized for an extended period,

• While connecting the inverter to the power source, make certain that the inverter is well removed from any potential source of flammable fumes or gases. • In the event a continuous audible alarm or automatic shut off, turn the inverter OFF immediately. Do not restart the inverter until the source of the problem has been identified and corrected. 23 pro1200to3000w.4/30/2010 8:55 AM Page 27 TROUBLESHOOTING TROUBLESHOOTING PROBLEM: TV Interference Overload LED on Problem Solution Electrical inter

Do not restart the inverter until the source of the problem has been identified and corrected. • To avoid battery drain, always disconnect the inverter when not in use. • Do not expose the inverter to moisture. • Avoid placing the inverter near sources of heat or in direct sunlight. • When in use, make certain that the inverter is properly ventilated. • Do not use the inverter near flammable materials, fumes or gases. • Always operate the inverter in accordance with the instructions in this manu

Important Information on Battery Chargers Using your inverter with battery chargers for power tools, flashlights, video cameras and laptop computers may cause damage to the inverter or the charging unit. Check with the appliance manufacturer for compatibility with modified sine wave inverters if you’re unsure. Although we advise against it, if you attempt to use a charging unit, monitor the temperature of the charging unit for approximately 10 minutes. If the charging unit becomes unusually warm

Induction motors may require 2 to 6 times their wattage rating to start up. For further information on the fundamental operating principles of Whistler inverters and related technical data, see "Technical Operating Principles." 7 INVERTER INFORMATION INVERTER INFORMATION pro1200to3000w.4/30/2010 8:54 AM Page 11 Don’t Push It. Although your Whistler power inverter has the capacity to provide power output (excess current) equal to approximately two times its rated wattage capacity brief period, it

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 inver

13 OPERATION OPERATION pro1200to3000w.4/30/2010 8:54 AM Page 17 Note: • Loose connections can result in a severe decrease in voltage which may cause damage and insulation. • Failure to make proper connection between the inverter and the power source will result in reverse polarity. Reverse polarity will blow the internal fuses in the inverter and may cause permanent damage to the inverter. Damage caused by reverse polarity is not covered under the Whistler warranty. • Making the connection betwe

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. •

Check Whistler’s online store for cable availability. Cable options: For model Pro-2500 at 10 foot length, a subsitute for the #0000 gauge can be using 2 sets of #0 gauge wires connected in parallel to the battery. 12 Making the Connection. 1. Make certain that the Power switch is in 2. Connect the cables to the power input at the rear of the inverter and tighten the screws to make a secure connection. (To make these connections, install the wire connectors flush with the metal backing plates an
