Figure 3-13 Installation of Single or Parallel Conductor Sets
Although a neutral terminal is available, a neutral conductor is not required for inverter operation. The neutral
terminal is bonded to chassis and only used for voltage sensing. If a neutral conductor is installed, torque the
neutral terminal based on the conductor size according to Table 3-3 using either 3/16 Allen hex key or a slot
torque driver.
