Installation
2.5.5 AC Conductor Wiring (ME2012, ME2512, and ME3112 models)
The following steps are basic guidelines for installing and connecting the AC wiring to and from
all ME Series inverters (except ME2000 Series model inverters—for instructions on wiring ME2000
Series model inverters, refer to Section 2.5.7). Before proceeding, refer to Table 2-3 to determine
your AC wiring confi gurations.
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 2-8).
2. Route the wires (hot, neutral, and ground) 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 wires.
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: You must connect to the HOT 1 IN terminal if you want to use the battery
charger.
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 2-9 to 2-13).
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 wires (hot, neutral, and ground) 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 wires.
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 2-9 to 2-13).
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 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 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.
