2.5.5 AC Conductor Wiring (ME2012, ME2512, and ME3112 models)
The following steps are basic guidelines for installing and connecting the AC wiring into and out of
the inverter. Refer to Table 2-3 to determine your AC wiring confi gurations before beginning.
WARNING: Before making any AC connections, make sure the inverter is disconnected
from the battery and there is no other source of live power connected to the inverter.
Wiring the Inverter AC Input
1. Remove the two Phillips screws on the AC Access Cover (see Figure 1-3, Item 15) to access
the internal AC Terminal Block (see Figure 2-10).
2. Route the cable from the AC electrical main panel through one of the strain relief clamps to
the AC INPUT. Tighten the strain relief clamp securely on the cable. Always leave a little extra
slack in the wiring.
3. Connect the hot wire (black) from the main panel's dedicated breaker to the "HOT 1 IN"
terminal. Tighten the "HOT 1 IN" terminal to 16 in lbf (1.8 N-m).
Info: Depending on the AC wiring confi guration, you may need to connect a wire to
the "HOT 2 IN" terminal, refer to your confi guration drawing (Figure 2-11 to 2-15).
4. Connect the neutral (white) from the main panel's neutral busbar to the "NEUT IN" terminal.
Tighten the "NEUT IN" terminal to 16 in lbf (1.8 N-m).
Wiring the Inverter AC Output
1. Route the cable from the inverter's AC OUTPUT to the AC electrical sub-panel (or outlets, if
using the output breaker versions) through the other strain relief clamp. Tighten the strain
relief clamp securely on the cable.
2. Connect the hot (black) wire from the "HOT 1 OUT" terminal to the sub-panel main breaker
(or to the hot connections on the outlets, if using the output breaker versions). Tighten the
"HOT 1 OUT" terminal to 16 in lbf (1.8 N-m).
Info: Depending on the AC wiring confi guration, you may need to connect a wire to
the "HOT 2 OUT" terminal, refer to your confi guration drawing (Figure 2-11 to 2-15).
3. Connect the neutral (white) from the "NEUT OUT" terminal to the sub-panel's neutral busbar
(or to the neutral connection on the outlets, if using the output breaker versions). Tighten the
"NEUT OUT" terminal to 16 in lbf (1.8 N-m).
Wiring the Inverter AC Ground
1. Combine the ground (green) wire from the main panel's ground busbar and the ground (green)
wire from the sub-panel's ground busbar (or the ground connection on the outlets, if using
the output breaker versions). After these grounds are combined, connect them to the "AC
GROUND" terminal. Tighten the "AC GROUND" terminal to 16 in lbf (1.8 N-m).
AC Wiring Inspection
1. Verify all cable 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 where it passes
through walls/bulkheads or other openings.
3. After verifying all AC connections are correct and all inverter AC terminal screws are torqued to
16 in lbf (1.8 N-m), replace the AC wiring access cover and the covers on the main electrical/
distribution panel.
