External AC Main Panel Wiring (see Figure 3-21b)
1. Route and attach a black wire from the MP enclosure’s AC LEG 1 IN busbar to the main AC

electrical panel.

2. Route and attach a red wire from the MP enclosure’s AC LEG 2 IN busbar to the main AC

electrical panel.

3. Route and attach a green wire from the MP enclosure’s GROUND busbar to the main AC electrical

panel’s Ground busbar.

4. Route and attach a white wire from the MP enclosure’s AC NEUTRAL busbar to the main AC

electrical panel’s Neutral busbar.

External AC Sub-Panel Wiring (see Figure 3-21b)
1. Route and attach a black wire from the MP enclosure’s AC LEG 1 OUT busbar to the AC electrical

sub-panel.

2. Route and attach a red wire from the MP enclosure’s AC LEG 2 OUT busbar to the AC electrical

sub-panel.

3. Route and attach a green wire from the MP enclosure’s GROUND busbar to the AC electrical

sub-panel’s Ground busbar.

4. Route and attach a white wire from the MP enclosure’s AC NEUTRAL busbar to the AC electrical

sub-panel’s Neutral busbar.

AC Wiring Inspection
After verifying all AC connections are correct, and all AC terminal screws are torqued correctly,

replace the covers on the main electrical panel/sub-panel.

Figure 3-20b, MPXS-60S / MPSL-60S AC Breaker Input Wire Transition

Bottom AC Breaker Wiring (see Figures 3-20b & 3-21b)

Info: Before proceeding any further,

disconnect the black AC LEG 1 IN cable from the

bottom left terminal of the AC breaker and reconnect to the bottom right terminal

as shown in Figure 3-20b

• Route and attach a red wire from the bottom terminal of the AC input breaker (B1) to the MP

enclosure’s AC LEG 2 IN busbar.

IMPORTANT:

Prior to installing the MPXS-60S’s external AC wiring, disconnect and then recon-

nect the AC LEG 1 IN black wire from the left breaker (B1) to the newly installed right breaker (B2),

as shown in Figure 3-20b. This ensures that the phase relationship (LEG 1/black on right to LEG 2/

red on left) between the AC input source and the output are correct.

Enclosure

NOTE: The AC LEG 1 IN wire is

moved from the B1 position to

the B2 position to ensure correct

input/output phase relationship.
