Caution Notice Caution: Rechargeable Appliances Warning Important Safety Information Introduction Intro Operation Customer Warranty Caution Warning Assistance Cobra 1000 Watt Output Waveform Some very sensitive electronic equipment may not operate satisfactory on “square wave” or “modified sine wave.” The output waveform is referred to as “square wave” or Installation Notes “modified sine wave.” It is a stepped waveform designed to have characteristics similar to the sine wave shape of Secondary Icons utility power. A waveform of this nature is suitable for most AC loads (including linear and switching power suppliers used in electronic equipment, transformers and motors). Notice Certain chargers for small nickel cadmium batteries can be damaged if connected to the Cobra 1000 watt inverter. Two particular types of equipment are prone to this problem: 1. Small battery-operated appliances Plug In Directly such as flashlights, razors, and night lights that can be plugged directly into an AC receptacle to recharge. 2. Certain battery chargers for Dangerous Voltages battery packs used in hand power tools. These chargers have a WARNING label stating that dangerous voltages are present at the battery terminals. This problem does not occur with the vast majority of battery operated equipment. Most use a separate charger or transformer that is plugged into the AC receptacle and produces a low voltage output. If the label on the AC adapter or charger states that it produces a low voltage AC or DC output (less than 30 volts), the inverter will have no problem powering the adapter safely. 2 Nothing Comes Close to a Cobra™ 3 10274_CPI1000_vC 8/14/07 3:48 PM Page 4 Main Icons Main Icons Intro Quick Evaluation Before Installation Introduction Intro Operation Customer Assistance Warranty Quick Evaluation Before Installation • This section provides you with basic information about the inverter and how to check its performance before installation. Be sure to have on hand: Installation Notes £ A 12 volt DC power source (such as a vehicle battery). Secondary Icons The power source must provide Power Source between 11 and 15 volts DC and be able to supply enough current to run the test load. As a rough guide, divide the wattage ofWarning the test load by Caution Notice 10 to get the current (in amperes) the power source must deliver. £ Cables to connect the power source to the inverter. Cables are supplied with the unit that are two feet long overall from the tip of the clamp shown to the stripped and tinned end for insertion in the Input End of the unit. If user supplied cables are to be used, they must be as short and thick as possible in order to reduce the voltage drop between the power source and the inverter when it is drawing current from the power source. If the cable suffers an excessive voltage drop, the inverter may shut down when drawing higher currents because the voltage at the inverter dropped below 10 volts. £ A test load that can be plugged into the AC receptacle on the inverter for short term testing at a low power level.

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. Notice Customer Assistance Warranty Connecting Cables Notes CAUTION We recommend a main fuse in the battery’s positive cable to protect against DC wiring short circuits (external to the inverter). The fuse should be as close to the battery as possible. We recommend a Buss Fuse ANL-250 Warranty or equivalent. The specific fuse ampere rating Caution Warning Notice should be sized to allow operation of all your DC powered equipment. CAUTION Remove any jewelry (watch, ring, etc.). Be Notes careful not to short circuit the battery with any metallic object (wrench, etc.). Installation Warranty 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 Operation Notes Connecting Cables Installation on e 8/14/07 Caution WARNING If you are making a permanent AC connection to the inverter, make sure that the AC wiring steps are performed before any DC wiring is Warning done. (DC hook-up energizes internal components, regardless of the position of the On/Off Switch). Working on AC connections in such a circumstance may result in an electric shock. 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 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. Explosion or fire may result. Thoroughly ventilate the battery compartment before making this connection. 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 Nothing Comes Close to a Cobra™ 11 Warranty Intro Power Consumption Installation 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. Main Icons Warranty 115 watts x 3 hours = 345 watt-hours Chassis Ground Customer Assistance 100 watts x 2 hours = 200 watt-hours • There is a screw on the rear panel for Chassis Ground.

Use copper wire Cautiona #8 AWG Warning (preferably with green/yellow insulation) to connect the chassis ground screw to the grounding point. Secondary Icons Operation 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 capacityCaution (a measure of how many amperes a 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. 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. 2. Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles. 3. 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.
