AC Connections

The AC connections consist of the 3 AC Phases (L1, L2, and L3), Neutral and Ground. AC wires must be rated
for at least 600 VAC. Use wires within the ranges shown in Table 3-2, and sized as required to comply with
local and National electrical codes.
Material
AC Output Copper
(L1, L2, L3)
Conductors Aluminum
Neutral Copper
(Bonded to
Ground) Aluminum
Electric Shock Hazard
Components with hazardous voltage and energy will electrocute the operator.
Ensure AC power doesn't flow into inverter. Verify with a multimeter.
Turn the AC Switch OFF before wiring. Wire the AC Connections as shown in Figure 3-15.
For the AC connections, use compression lugs with a single hole for a ½ in or M12 stud and sized for the wire
gauge used. The width of the lugs must be 1.5 in (38 mm) or less. Torque to 220 in-lbs (25 N-m) using an
18mm socket and torque driver. A hex nut and washer are provided. The terminal block accepts single or
parallel conductor sets. See Figure 3-17 for the hardware assembly instructions.
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 Error! Reference source not found. using either
3/16 Allen hex key or a slot torque driver.
