Power wire and wiring are very important to the performance of the inverter. Because the inverter has a low voltage, high current input, low resistance wiring is essential between the battery and inverter. This is so it can deliver the maximum amount of energy to the load.
Keep the cable length as short as possible, no more than four feet (one and a half meters). This will keep the voltage drop to a minimum.
If the cable has too much voltage drop, the inverter may shut down when drawing higher currents because voltage at the inverter may drop below 10 volts. If you must use longer cables, choose thicker cables, such as #2 AWG, and trim the ends of the cable to fit the terminals.
To connect the cables between the inverter and the battery:
1.Press the Power Button on the inverter to the off position. If the power source is a DC power supply, switch it off as well.

2.Connect cable to the Power Input Terminals on input end of the inverter. The red terminal is positive (+) and the black terminal is negative
It is a good idea to check and tighten these screws from time to time. They can become loose by vibrations or thermal cycling.

3.Connect cables to the power source:
a.Connect the cable from the Negative (Black) Terminal of inverter to the Negative Terminal of the power source. Make a secure connection.
