User manual COBRA CPI 1500

[. . . ] Introduction Our Thanks To You Thank you for purchasing the Cobra® CPI 1500 inverter. Properly used, this Cobra® product will give you many years of reliable service. Operating Instructions How Your Cobra® Power Inverter Works The Cobra® Power Inverter is an electronic product that has been designed and built to take low voltage DC (Direct 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 household appliances and electronic products in automobiles, RVs, boats, tractors, trucks and virtually anywhere else. Customer Assistance Customer Assistance Should you encounter any problems with this product, or not understand its many features, please refer to this owner's manual. [. . . ] 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 1500 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 English Nothing comes close to a CobraTM 11 Installation Power Consumption Installation Ground Wiring · · 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 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. Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles. Calculate th 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 Power Consumption Ground Wiring 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 the unit is installed. Use a #8 AWG copper wire (preferably with green/yellow insulation) to connect the chassis ground screw to the grounding point. Chassis Ground 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. 100 Watts x 2 hours = 200 Watt-Hours 115 Watts x 3 hours = 345 Watt-Hours 300 Watts x 15 min = 75 Watt-Hours 4. Divide the watt-hours by ten (10) to determine how many power supply's (12 volt) ampere-hours will be consumed. 12 English Nothing comes close to a CobraTM 13 Operation Power On & Off · Operation Remote On/Off Switch Turning Your Inverter On or Off Be sure to have your power inverter properly installed before attempting to turn the unit On (see "Installation" page 6). If a DC power supply is being used as the power source, switch it On. On the left side panel, switch the On/Off Switch to On. On/Off Switch to On NOTE The On/Off Switch turns the control circuit in the inverter On and Off. [. . . ] It will be necessary to furnish the following to have the product serviced and returned. For Warranty Repair include some form of proof-of-purchase, such as a mechanical reproduction or carbon copy of a sales receipt. If you send the original receipt, it cannot be returned; 2. Enclose a description of what is happening with the power inverter. [. . . ]
