Connecting Cables (not included)

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.
Use only copper wire. Aluminum wire has about
We recommend #4 AWG copper cable (90°C insulation rating) as the minimum size for connections between the battery and inverter.
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.Turn the On/Off Switch on the inverter to the off position. If the power source is a DC power supply, switch it off as well.

3.Connect cable to the Power Input Terminals on right side panel of the inverter. The red terminal is positive

4.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.
