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.

[. . . ] WARNING You may observe a spark when making the connection because current can flow to charge the capacitors in the inverter. Do not make this connection in the presence of flammable fumes. Thoroughly ventilate the battery compartment before making this connection. n Customer Assistance Warranty Installation Secondary Icons n You might observe a spark when you make this connection since current can flow to charge capacitors in the inverter. Notes All power connections to your Cobra inverter must be Positive to Positive and Negative to Negative. CAUTION Electrical installations must meet local and national wiring codes, and should be performed by a qualified electrician. CAUTION Do not connect the inverter and another AC source (such as a generator or utility power) to the AC wiring at the same time. The inverter will be damaged if its output is connected to AC voltage from another source. Damage can even occur if the inverter is switched off. CAUTION Do not connect the inverter to an AC branch circuit that has high-power consumption loads. It will not operate electric heaters, air conditioners, stoves, and other electrical appliances that consume more than 2500 watts. CAUTION Loose connectors result in excessive voltage drop and may cause over heated wires and melted insulation. CAUTION Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and may permanently damage the unit. Such damage is not covered by the warranty. 10 Notice Caution Caution Warning Nothing Comes Close to a CobraTM 11 10276_CPI2575_PH1 Intro Operation 8/20/07 Warranty 2:33 PM Page 12 Intro Operation Customer Assistance Warranty Customer Assistance Installation Installation Power Consumption Notes Installation Installation Ground Wiring Notes Power Consumption Secondary Icons · Ground Wiring Secondary Icons · In a vehicle: Connect the Chassis Ground to the chassis of the vehicle.

Divide the watt-hours by 10 to determine how many battery (12 volt) ampere-hours will be consumed. 12 Secondary Icons Intro Installation Operation Notice Customer Assistance Caution Notes Warranty Warning For each piece of equipment you will be operating from the inverter, you must determine the battery's reserve capacity (how long the battery can deliver a specific amount of current ­ in automotive batteries, usually 25 ampere) or ampere-hour capacity (a measure of how many amperes a Caution Warning Notice battery can deliver for a specified length of time). 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. [. . . ] See customer assistance on page A1.
