AC Connections
The AC connections consist of the 3 AC Phases (L1, L2, and L3) 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 the
National Electrical Code and local codes.
Inverter Models
AC Output Conductors
(L1, L2, L3)
AC Neutral
Turn the AC Switch OFF before wiring. Wire the AC Connections as shown in Figure 3-12. For the AC
connections, use compression lugs with a single hole for a ½" or M12 stud and sized for the wire gauge used.
The width of the lugs must be 1.5" (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 3-12 for the hardware assembly instructions.
