[. . . ] Introduction Intro Our Thanks to You Operation Customer Warranty Thank you for purchasing Assistance the Cobra CPI 2550 inverter. Properly used, this Cobra product will give you many years of reliable service. Operating Instructions How Your Cobra Power Inverter Works Installation Notes The Cobra power inverter is an electronic product that has been Secondary Icons and built to take low voltage DC (Direct designed Current) power from your automobile or other low voltage power supplies and convert it to standard 115 volt AC (Alternating Current) power like the current you have in your home. This conversion process thereby allows you to use many of your householdCaution appliances Warningelectronic and Notice products in automobiles, RVs, boats, tractors, trucks and virtually anywhere else.

[. . . ] Thoroughly ventilate the battery compartment before making this connection. NOTE If only one power source is used, connect both cables from the negative terminal of the inverter to the negative terminal of the power source. Then connect Caution Warning both cables from the positive terminals of the inverter to the positive terminal of the power source.

Example ­ Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25 ampere for 180 minutes before it is completely discharged. Example ­ Ampere-hour capacity: a battery with an ampere-hour capacity of 100 ampere-hours can deliver 5 ampere for 20 hours before it is completely discharged. To determine the battery ampere-hour capacity you require: 1. Determine how many watts each piece of equipment consumes. This can normally be found on the product label. If only the current draw is given, multiply the current draw by 115 to get the watt consumption. Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles. Calculate the total watt-hours of energy consumption (power x operating time) using the average power consumption and the total estimated running time (in hours). Power x Operating Time = Watt-Hours. Laptop TV/VCR (up to 25") Blender There is a screw on the rear panel for Chassis Ground. This is to connect the chassis of the inverter to ground. The Chassis Ground Screw must be connected to a grounding point, which will vary depending on where Operation Customer Warranty Intro the unit is Notice installed. Use a #8 Assistance copper wire AWG Warning Caution (preferably with green/yellow insulation) to connect the chassis ground screw to the grounding point. Chassis Ground Secondary Icons Installation Notes Notice Caution Warning In a vehicle: Connect the Chassis Ground to the chassis of the vehicle. In a boat: Connect to the Boat Grounding System. In a fixed location: Connect the Chassis Ground Screw to earth ground by connecting to a ground rod (a metal rod pounded into the earth) or other proper service entrance ground. 50 watts x 2 hours = 100 watt-hours 115 watts x 3 hours = 345 watt-hours 300 watts x 15 minutes = 75 watt-hours 4. Divide the watt-hours by 10 to determine how many power supply's (12 volt) ampere-hours will be consumed. 12 English Nothing comes close to a Cobra® 13 Installation Notes Operation Intro Operation Power On and Off Main Icons Secondary Icons Operation Intro Operation Remote On /Off Switch Customer Warranty · Be sure to have your power inverter properly installed before attempting to turn the unit on (see installation page 6).
