User manual COBRA CPI 880 QUICK START GUIDE

[. . . ] Introduction Our Thanks to You Thank you for purchasing the Cobra CPI 880 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. The Cobra line of quality products includes: Customer Assistance CB Radios microTALK® Radios Radar/Laser Detectors Safety Alert® Traffic Warning Systems Mobile GPS Navigation Systems HighGear® Accessories CobraMarine® VHF Radios CobraMarine® Chartplotters Power Inverters Accessories Customer Assistance Should you encounter any problems with this product, or not understand its many features, please refer to this owner's manual. [. . . ] It is better and cheaper to run longer AC wires than longer DC wires (cables). CAUTION To avoid fire, do not cover or obstruct ventilation openings. Do not install inverter in a zeroclearance compartment. CAUTION The inverter must only be connected to batteries with a nominal output voltage of 12 volts. It will not work with a 6 volt battery, and will be damaged if it is connected to a 16 volt battery. WARNING This unit contains components which can produce arcs or sparks. To prevent fire or explosion, do not install in compartments containing a battery or flammable materials, or in a location which requires ignition protected equipment. Connect Test Load USB Connection 4 Nothing Comes Close to a Cobra® 5 Installation Mounting · Installation Connecting Cables · Mounting To mount your inverter: 1. Place the inverter on a flat surface with the mounting bracket against the mounting surface. Mounting Brackets Connecting Cables Power wire and wiring are very important to the performance of the inverter. Because the inverter has a low voltage, high current input, low resistance wiring is essential between the battery and inverter. This is so it can deliver the maximum amount of energy to the load. 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. 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 Installation Power Consumption Operation Power On and Off Power Consumption · 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 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 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 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.
