2.5.7 AC Conductor Wiring (ME2000 models)

The ME2000 offers a cost-effective alternative to the ME2012 while still providing the same

features. This model has a slightly smaller height, but otherwise has the same footprint as the

other ME Series inverters. The ME2000 uses wire leads to connect the AC wires and can be wired

in a single in-single out conﬁ guration, as well as a single in-dual out conﬁ guration (-15B & -20B).

The following steps are basic guidelines for installing and connecting the AC wiring into and out

of the inverter. Refer to Table 2-4 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 all AC power is disconnected from the inverter.

Wiring the Inverter AC Input

1. Remove the two Phillips screws on the AC access cover (Figure 1-3, Item 15) to access the

internal AC wiring.

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 AC hot in wire (BLACK) from the main panel’s dedicated breaker to the inverter’s

(BLACK) HOT IN wire using ﬁ eld wiring leads.

4. Connect the AC neutral in wire (WHITE) from the main panel’s neutral busbar to the inverter’s

(WHITE) NEUTRAL IN wire using ﬁ eld wiring leads.

Wiring the Inverter AC Output

5. 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.

6. Connect the inverter’s HOT 1 OUT (BLUE) wire to the sub-panel main breaker (or, to the hot

connections on the outlets if using the output breaker versions) using ﬁ eld wiring leads.

Info: Depending on the AC wiring conﬁ guration, you may need to connect a wire to the

inverter’s HOT 2 OUT (ORANGE) wire (see Figure 2-16).

7. Connect the inverter’s NEUTRAL OUT (WHITE w/BLACK) wire to the sub-panel’s neutral busbar

(or to the neutral connections on the outlets, if using the output breaker versions – see Figure

2-16) using ﬁ eld wiring leads.

Wiring the Inverter AC Ground

8. 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, use ﬁ eld wiring leads to connect

them to the inverter’s AC GROUND (green) wire.

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/bulkheads or other openings.

3. After verifying all AC connections are securely fastened, replace the AC wiring access cover

and the covers to the main electrical/distribution panel.
