Neutral Requirements
The neutral conductor is used by the inverter for voltage sensing only and does not carry current. Therefore, the neutral
conductor size may be reduced to a size no smaller than the ECG.
Depending on the authority having jurisdiction (AHJ), it is permissible to install the provided neutral to ground jumper. In
this configuration, no neutral conductor is required. If terminated properly, this connection will not affect the function of
the inverter. Always check with the AHJ before removing the neutral conductor and installing the neutral to ground
jumper.
NOTICE !
Neutral to Ground Jumper: Do not use a jumper between neutral and ground if the neutral conductor is connected.
Using a jumper with then neutral conductor connected may result in damage and void the warranty.
AC Conductor Specifications
Yaskawa Solectria requires the use of 90°C minimum rated conductors.
With longer wire runs, the use of larger conductors than those required by the NEC can help minimize voltage drop and
increase system efficiency.
The AC connections consist of 3 phases (L1, L2, and L3), ground, and neutral. Conductors must be rated for a minimum
of 600 V. Use conductors in accordance with Table 3-2
.
