Installation

To make the neutral connections:

1.Ensure there is only one neutral-to-ground bond in the system. In this case, it would be in the main AC distribution panel.

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.

2.Connect the neutral (white) wire from the neutral bar in the main AC distribution panel to one of the neutral terminals in the ACCB.

3.Connect a neutral (white) wire from the sub panel to one of the neutral terminals in the ACCB.

4.Connect the factory-installed neutral wire (white) in the ACCB to the NEU1 terminal in the inverter.

5.Connect the neutral (white) wire from the generator (or generator disconnect) and connect it to one of the neutral terminals in the ACCB.
