1,Installation Connection

1,Red terminal: Connect DC positive, black terminal: Connect DC negative. Show in Figure 1.

Figure 1

2,AC socket: Connect to the mains. Put the side of the AC cord which has holes into the inverter with 3 foot outlet and the other side of the AC cord to home 3PIN AC outlet. Show in Figure 2.

Figure 2 Figure 3

3,Switch: Connect the connections in right way, then turn on the switch. The inverter starts to work. Show in Figure 3.

2,Stack using
