Installation
2.5.3 Recommended GFCIs (Ground Fault Circuit Interrupters)
Some electrical safety codes require the use of GFCI’s. In compliance with UL standards, Sensata
Technologies has tested the following GFCI outlets and fi nd that they function properly when
connected to the inverter’s AC output:
CAUTION: Ground Fault Circuit Interrupters (GFCIs) shall be installed in the recreational
vehicle wiring system to protect all branch circuits.
WARNING: Risk of electrical shock. Use only ground-fault circuit interrupters
[receptacles(s) or circuit breaker(s)] that are compatible with your ME inverter. Some
types may fail to operate properly when connected to this inverter equipment.
2.5.4 AC Terminal Block Connections (ME2012, ME2512, and ME3112)
The ME2012, ME2512, and ME3112 models have a six-pole AC terminal block and one AC ground
terminal to connect the inverter’s AC input and output wiring. This terminal block (see Figure 2-9)
allows a service/distribution panel (main panel) to be wired to the inverter’s input, and also allows
a dedicated panel (sub-panel) between the inverter’s output wiring and the AC loads. To access
and view the AC terminal block and ground terminal, remove the two Phillips screws holding the
AC wiring access cover plate (see Item 15, Figure 1-3).
Each connection on the AC terminal block is rated to accept one #14 to #6 AWG (2.1 to 13.3
mm
2
) CU stranded wire, or two #12 AWG (3.3 mm
2
) CU stranded wires. The connection uses a
M3.5 slotted head screw, and the maximum tightening torque is 16 lbf-in (1.8 N-m).
Info: One of the AC wiring confi gurations [SI/SO (60A), Figure 2-11] uses a #6 AWG
(13.3 mm
2
) CU wire to carry 60 amps, and splits to two wires to allow 30 amps for
each leg (i.e., AC HOT1 and AC HOT2). IDEAL Industries Inc. (www.idealindustries.
com) manufactures a crimp connector (PN: 412) and a separate insulator (PN: 417)
that allow up to two #8 AWG (8.4 mm
2
) wires, with one #6 AWG (13 mm
2
) wire to be
connected together.
Info: To comply with ABYC requirements for marine installations, the AC terminal has
a stainless steel wire protector to prevent wire damage from the set-screw.
Info: The inverter’s NEUT IN and NEUT OUT terminals are electrically isolated from
each other while inverting. This is related to the neutral-ground bonding requirement
and helps to prevent ground-loops (see Section 2.6.3 for more information).
The AC ground terminal can accept one #14 to #6 AWG (2.1 to 13 mm
2
) CU stranded wire. It
uses a slotted head screw and has a recommended maximum tightening torque of 45 lbf-in (5.1
N-m). For multiple ground wires, use a pressure or mechanical connector to attach the single wire
from the AC ground terminal to the input and output ground connections.
