2.5.6 AC Wiring Confi gurations (MS2012, MS2812, MS2024, MS4024)
The following table provides the different wiring confi gurations for installing and connecting the AC
conductors to and from the inverter (refer to Figures 2-9 to 2-13 for installation drawings showing
these confi gurations). Refer to Table 2-4 (and Figures 2-14 & 2-15) for the MS2000 models.

Note 1 – AC Source is from either the utility/grid power (i.e., shorepower) or an AC generator.
Note 2 – If two legs of 30A @ 120 VAC are used, they must be from the same source (i.e., have a common
neutral).
