Be sure to have on hand: Installation Notes A 12 volt DC power source (such as a vehicle battery). Secondary Icons 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. As a rough guide, divide the wattage of the test load by Notice Caution Warning 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. The following cables are recommended for testing low power level test loads only.
