2.5.5 AC Conductor Wiring
The following steps are basic guidelines for installing and connecting AC wiring to and from an MSH-
RE Series inverter. The fi rst section covers the AC wiring needed to connect the inverter to utility
power, and the second section covers the AC wiring needed to connect the inverter to a generator.
WARNING: Before making any AC connections, make sure the inverter is disconnected
from the battery and no AC power is connected to the inverter.
Info: Connecting to either AC1 or AC2 input allows battery charging.
Remove the two Phillips screws on the AC wiring access cover (Item 15, Figure 1-3) to access
the internal AC terminal block (see Figure 2-8).
Wiring the Inverter AC1 Input (Grid/Utility)
1. Route the wires (HOT1, NEUTRAL1, and GROUND1) from the AC electrical main panel through
one of the strain relief clamps on the inverter (Item 8, Figure 1-2). Tighten the strain relief
clamp securely on the wires. Always leave a little extra slack in the wiring. Refer to Figure 2-9.
2. Connect the HOT1 wire (black) from the main panel's dedicated breaker to the inverter's AC1
(GRID IN) terminal.
3. Connect the NEUTRAL1 (white) from the main panel's neutral busbar to the inverter's NEUTRAL
IN terminal.
4. Connect the GROUND1 (green or bare copper) wire from the inverter's AC GROUNDS terminal
to the main panel's ground busbar.
Wiring the Inverter AC2 Input (Generator)
1. Route the wires (HOT2, NEUTRAL2, and GROUND2) from the generator through one of the
strain relief clamps on the inverter (Item 8, Figure 1-2). Tighten the strain relief clamp securely
on the wires. Always leave a little extra slack in the wiring. Refer to Figure 2-9.
2. Connect the HOT2 wire (black) from the generator's dedicated breaker to the inverter's AC2
(GEN IN) terminal.
3. Connect the NEUTRAL2 (white) from the generator's neutral busbar to the inverter's NEUTRAL
IN terminal.
4. Connect the GROUND2 (green or bare copper) wire from the inverter's AC GROUNDS terminal
to the generator's ground busbar.
Wiring the Inverter AC Output
1. Route the wires (HOT, NEUTRAL, GROUND) through the unused strain relief clamp on the
inverter (Item 8, Figure 1-2) to the AC electrical sub-panel (or outlets, if using the output
breaker versions). Tighten the strain relief clamp securely on the wires.
2. Connect the HOT (black) wire from the inverter's HOT OUT terminal to the sub-panel's main
breaker.
3. Connect the NEUTRAL (white) from the inverter's NEUTRAL OUT terminal to the sub-panel's
neutral busbar (or to the neutral connection on the outlets if using the output breaker versions).
4. Connect the GROUND (green or bare copper) wire from the inverter's AC GROUNDS terminal
to the sub-panel's ground busbar.
AC Wiring Inspection
1. Verify all wire runs are secured. If installed in a mobile installation, use wire ties or other non-
conductive fasteners to prevent chafi ng or damage from movement and vibration.
2. Verify strain reliefs or grommets are in place to prevent damage to the wiring or conduit where
it passes through walls or other openings.
3. Verify that all AC connections are correct, all the inverter AC terminal screws are torqued to a
maximum tightening torque of 32 in lbf (3.6 N-m), and the AC ground terminal is torqued to
a maximum tightening torque of 45 in lbf (5.1 N-m).
4. Replace the AC wiring access cover and the covers on the main electrical/distribution panel.
