[. . . ] 10273_CPI875_PH2 7/10/07 6:04 PM Page 1 Main Icons Introduction Intro Our Thanks to You Operation Customer Warranty Thank you for purchasing Assistance the Cobra CPI 875 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 designed and built to take low voltage DC (Direct Secondary Icons 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.

[. . . ] Connect the cable from the Positive (Red) Terminal of the inverter to the Positive Terminal of the power Caution Warning Notice source (the battery's main fuse or the battery selector Secondary Icons switch, if you are using one). You might observe a spark when you make this connection since current can flow to charge capacitors in the inverter. All power connections to your Cobra inverter must be Positive to Positive and Negative to Negative. Operation Customer Secondary Icons Assistance Caution Warning Installation CAUTION Reverse polarity connections (positive Warranty to negative) will blow internal fuses in the inverter and may permanently damage the unit. Such damage is not covered by the warranty. CAUTION Remove any jewelry (watch, ring, etc. ). Notes Be Notice notCaution careful to short circuit the battery with Warning any metallic object (wrench, etc. ). WARNING 115 volt AC power is potentially lethal. Do not work on AC wiring when it is connected to the inverter (even if it is switched off) unless the Warning 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. Do not make this connection in the presence of flammable fumes. Thoroughly ventilate the battery compartment before making this connection. Notice Caution Connect Power Source n Customer Assistance Warranty n Notes Caution Warning 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 800 watts. CAUTION Loose connectors result in excessive voltage drop and may cause over heated wires and melted insulation. 8 Nothing Comes Close to a Cobra® 9 10273_CPI875_PH2 Intro Operation 7/10/07 Customer Assistance 6:04 PM Page 10 Main Icons Main Icons Warranty Installation Installation Power Consumption Notes Operation Intro Intro Power On and Off Operation Customer Assistance Warranty Power Consumption Secondary Icons · 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 amperes) or ampere-hour capacity (a measure of how many amperes Caution Warning Notice a battery can deliver for a specified length of time). Example ­ Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25 amperes for Main Icons 180 minutes before it is completely discharged. Example ­ Ampere-hour capacity: a battery with an ampere-hour capacity of 100 ampere-hours can deliver Main Icons 5 amperes 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.
