To make the neutral connections:

1. Create only one neutral-to-ground bond in the system. In this case, it 

would be in the main AC distribution panel. 

2. Connect the neutral (white) wire from neutral bar in the AC 

distribution panel to one of the neutral terminals in the 

ACCB

.

3. Connect the factory-installed neutral wire (white) in the 

ACCB

 to the 

NEU2 terminal in the inverter.

4. Connect the neutral (white) wire from the generator and connect it to 

one of the neutral terminals in the 

ACCB

.

Important:

Ensure there is only one neutral-to-ground bond in the entire 

system. See the Sine Wave Plus Inverter/Charger Owner’s Manual for additional 
information regarding the neutral-to-ground bond requirements.
