The neutral conductor from the inverter to point of interconnection (POI) is optional. The function of the
neutral, when used, is to provide a point of reference for measurement purposes that is essentially at ground
potential. The neutral conductor is for control or measurement purposes only, and therefore may be sized
according to NEC section 705.95(B). The ground conductor (PE) is sized to section 250.122.
Use the OT type terminal to connect the AC conductors to the AC terminal block and connect the PE (GND) cable
to the grounding terminal block. The neutral conductor is optional. While the inverter may be wired as a 3-wire or
4-wire connection, the PE ground is ALWAYS required. When terminating the ground at the busbar a ferrule is
recommended but not required. (See the 1st diagram in Figure 3-35) Set up the conductors referring to Figure
3-35. End ferrules and OT type terminals are not provided by Yaskawa Solectria Solar.
