AC Breaker
The AC breaker is attached within the MP enclosure and functions as the inverter’s AC input discon-
nect switch.
1. While holding the new AC breaker against the MP’s mounting plate, align the breaker’s four mount-
ing holes with the enclosure’s mounting holes (see Figure 3-9). Note: The AC breakers are always
installed in the left enclosure of a MP dual enclosure (see Figure 3-10).
2. Use the supplied four #8-32 x 1/4” T20 screws (Figure 2-2, Item 4) to hold the AC breaker in
place. Do not fully tighten the screws, that will be done in the next step after ensuring proper
alignment with the MP enclosure’s cover.
3. Check the AC breaker alignment by temporarily placing the MP’s front panel cover over the AC
breakers. If the fi t and alignment are correct, tighten all Torx screws to secure the new AC breaker.
