[. . . ] 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. Mounting hardware should be corrosion resistant and at least #10 or larger. The inverter can be mounted horizontally or vertically. Mounting 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: 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 done. (DC hook-up energizes internal components, regardless of the position of the ON/OFF switch). 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 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. 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. [. . . ] PROTECTION OVERLOAD, SHORT-CIRCUIT, OVERTEMP 16. REVERSE POLARITY, UNDER/OVER VOLTAGE Notes All protection is automatically recovered. To protect the battery, if the unit needs to be restarted after low voltage protection, the voltage of DC input should be above 12V. To extend the life of the fan it will stop when there is no load.
