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.

[. . . ] Do not work on AC wiring when it is connected to the inverter (even if it is switched off) unless the DC power source is physically disconnected from the inverter. Also, do not work on AC wiring if it is connected to another AC power source such as a generator or the utility line. WARNING You may observe a spark when making the connection because current can flow to charge the capacitors in the inverter. 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. 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 1000 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 10274_CPI1000_vC Intro Operation 8/14/07 Customer Assistance 3:48 PM Page 12 Intro Operation Customer Assistance Warranty Warranty 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. 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.

Divide the watt-hours by 10 to determine how many battery (12 volt) ampere-hours will be consumed. 12 Nothing Comes Close to a CobraTM Secondary Icons Intro Operation Installation 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. 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. There is a screw on the rear panel for Chassis Ground. The Chassis Ground Screw must be connected to a grounding point, which will vary depending on where the unit is Notice installed.
