User manual COBRA HIGH GEAR PI 1000

[. . . ] 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 that 30 volts) the inverter will have no problem powering it safely. Cobra 2000W Output Waveform The output waveform is referred to as "square wave" or "modified sine wave. " It is a stepped waveform designed to have characteristics similar to the sine wave shape of 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). 2 3 Quick Checkout Quick Checkout Quick Checkout This section provides you with basic information about the inverter and how to check its performance before installation. Be sure to have the following on hand: · A 12 volt DC power source (such as a vehicle battery) · A set of cables to connect the power source to the inverter · A test load that can be plugged into the AC receptacle on the inverter Testing/Connection Testing Test Load Power 100 w 250 w 500 w Testing Minimum Cable Size # 16 AWG copper # 12 AWG copper # 8 AWG copper Power Source The power source must provide between 11 and 15 volts DC and be able to supply enough current to run the test load. [. . . ] Switch the inverter's ON/OFF switch to the On position and turn the test load On. If it does not, please consult the troubleshooting section in this manual. 6 7 Installation Installation CAUTION: To avoid fire, do not cover or obstruct ventilation openings. 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. Mounting/Cables Installation The inverter must be installed in an area that meets all of the following requirements: A. Dry- Do not place in an area where water can drip or splash on the inverter. Cool- Ambient air temperature should be between 30° F and 105° F (0° C and 40° C). Ventilate- Allow at least 1 inch (3cm) of clearance around the inverter for proper airflow. Make sure that ventilation openings on the ends of the unit are not obstructed. Safe- Do not install the inverter in the same compartment as a battery or in any compartment that contains flammable liquids such as gasoline. Close to battery- Install unit as close to battery as possible (without being in the same compartment) to minimize the length of cable required to connect the inverter to the battery. It is better and cheaper to run longer AC wires than longer DC wires (cables). Mounting Mount the inverter on a flat surface placing the mounting bracket on the bottom. Use a #8 AWG copper wire (preferably with green/yellow insulation) to connect the chassis ground screw to the grounding point. · 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. 10 11 DC Wiring DC Wiring CAUTION: Loosely tightened connectors result in excessive voltage drop and may cause over heated wires and melted insulation. It does not disconnect power from the inverter. Operating Limits The inverter will operate most AC loads within its power rating. Some induction motors used in freezers, pumps, and other motor-operated equipment require very high surge currents to start. The inverter may not be able to start some of these motors even though their rated current draw is within the inverter's limits. The inverter will normally start single phase induction motors rated at 1/2 HP or less Operating Limits 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. Don't worry about excessive drain on the battery if you leave the inverter switched On for a few days. However, do switch it off if you are not planning be recharge the battery within a week or so. Input Voltage The inverter will operate from input voltage ranging from 10 volts to 15 volts. Optimum performance will occur when the voltage is between 12 volts and 14 volts. If the voltage drops below 10. 5+/-0. 3V volts, an audible low battery warning will sound. The inverter will shut down if the input voltage drops below 9. 5V+/-0. 3V volts.
