(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, it is possible that the battery voltage may be drained to the point where the battery has insufficient reserve power to start the vehicle. 10 • It may be advisable to operate from a bank of batteries of the same type Two such batteries will generate single battery; three batteries will generate three times the Ah and so on. See “Making on page 13 for more information. This multiple parallel battery option is especially recommended for the Pro-2500W and Pro-3000W inverters due to the high level of amps these models require to produce up to 3000 watts of continuous load.

Wire Cable Gauges For safe and proper operation of the inverter, connect the inverter to the power source with the proper gauge available and in the shortest length practical. Pro-1200W and Pro-1600W When the inverter and the battery are set up within three feet of each other, use a minimum of #4 gauge wire to make the connections. Within four to six feet, use a minimum of #2 gauge wire (Pro-1200W), #0 gauge for Pro-1600W. At distances between six feet to ten feet, use #0 gauge wire (Pro-1200W), #00 gauge for Pro-1600W. 11 CABLE INFORMATION OPERATION pro1200to3000w.4/30/2010 8:54 AM Page 15 Pro- 2000W and Pro-2500W When the inverter and the battery are set up within three feet of each other, use a minimum of #2 gauge wire to make the connections. Within four to six feet, use a #0 gauge (Pro-2000W), #00 gauge for Pro-2500W. At distances between six feet to ten feet, use #000 gauge (Pro2000W), #0000 for Pro-2500W connected in parallel to the battery. Pro-3000W When the inverter and the battery are set up within three feet of each other, use a minimum of #0 gauge wire to make the connections. Within four to six feet, use a #000 gauge wires. At distances between six feet to ten feet, use 2 sets of #00 gauge wires connected in parallel to the battery. 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 and fasten the nuts securely. 3. Connect the cable from the Negative (-) terminal on the inverter to the Negative (-) terminal on the 12 volt power source. Make certain the connection is secure. 4. Confirm that the cable you have just installed is properly connected. Specifically, make certain that the cable is connected to the Negative (-) terminals on both the inverter and the 12 volt power source. 5. Connect the cable from the Positive (+) terminal on the inverter to the Positive (+) terminal on the power source. 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 between the Positive (+) terminals may cause a spark as a result of current flowing to the capacitors in the inverter. This is a normal occurrence. Due to the potential for sparking, however, it is extremely important that both the inverter and the 12 volt battery be well removed from any possible source of flammable fumes or gases. Failure to heed this warning could result in fire or explosion. 6. Run a ground from the Ground Lug Terminal at the rear of the inverter to a proper grounding point using the shortest practical length of 18 AWG wire. Selection of the grounding point will depend on where you are using the inverter. The ground wire may be connected to the chassis of your vehicle or to the grounding system in your boat or to the earth* if you are operating the inverter in a remote location. Before connecting the ground, make certain that the inverter is turned off. Operating the inverter without properly grounding it may result in electrical shock. * This ground can’t be the same ground as the AC ground. 14 7....
