Wiring for On-Grid Applications Using an AC Distribution Panel

To make the ground connections:

1.Prepare the primary system ground and connect it to the ground bar in the main AC distribution panel. See the Sine Wave Plus Inverter/ Charger Owner’s Manual for information regarding preparing the primary system ground.

2.Connect a ground wire (green) from the main AC distribution panel to the ground bar in the sub panel.

3.Route cable(s) (hot, neutral, and ground) from the main AC distribution panel through one of the knockouts prepared in the ACCB and connect the ground wire (green) to the ground bar in the ACCB.

4.Connect the factory-installed ground wire (green) in the ACCB to the AC ground bar in the inverter.

5.Connect the ground wire (green) from the generator to the ground bar in the main AC distribution panel.
