Step #2: Wiring Inverter to 12 volt Power
The power inverter requires connection to a standard 12 volt DC power source as found in most cars,
trucks, RVs and boats. The power source must provide between 11 and 15 volts DC. The power
source must be able to provide sufficient current to power the load. See the chart below that shows
minimal wire sizing and current draw at full load.

Always connect the positive, red (+) terminal to the positive connection and the negative, black (-)
terminal to the negative or ground side of the power system.
WARNING
Failure to connect the correct polarity may cause damage to the power inverter
and/or your electrical system and is not covered by the warranty.
Installation Tip
To minimize electrical interference, keep the DC power cables as short as possible
and twist them with 1 to 3 twists per foot. This minimizes radiated interference
from the cables.
