User manual COBRA CPI 2500

[. . . ] Introduction Our Thanks To You Thank you for purchasing the Cobra® CPI 2500 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. [. . . ] Working on AC connections in such a circumstance may result in an electric shock. 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. NOTE If only one power source is used, connect both cables from the negative terminal of the inverter to the negative terminal of the power source. Then connect both cables from the positive terminals of the inverter to the positive terminal of the power source. 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. 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. Laptop TV/VCR (up to 25") Blender Power Consumption Ground Wiring 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 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 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). 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. When the switch is in the Off position, the inverter draws no current from the battery. When it's in the On position, but no power is being supplied to the load, the inverter draws less than 500 milliamperes from the battery. It would take more than a week to discharge a 100 amperehour battery at this rate depending on the age of the battery. · An optional Remote On/Off Switch (not included) can be connected to the Remote Jack allowing you to turn the Cobra® CPI 2500 Inverter On or Off from a convenient location when the inverter is installed in an out of reach location. [. . . ] In the event of misuse or abuse of the product or as a result of unauthorized alterations or repairs. All implied warranties, including warranties of merchantability and fitness for a particular purpose are limited in duration to the length of this warranty. Cobra® shall not be liable for any incidental, consequential or other damages; including, without limitation, to damages resulting from loss of use or cost of installation. Some states do not allow limitations on how long an implied warranty lasts and/or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you. ® Very little maintenance is required to keep the inverter operating properly.
