Recommended GFCI (Ground Fault Circuit Interruption) Outlets

In compliance with UL standards, Sensata has tested the following GFCIs and found that they
function properly when connected to the inverter's AC output:
• Cooper VGF15W
• Leviton 8899-A, N7899, GFNT1 and GFNT2 Series
WARNING: Risk of electrical shock. Use only ground-fault circuit interrupters
[receptacle(s) or circuit breaker(s)] compatible with your MSH3012RV inverter/charger.
CAUTION: GFCIs shall be installed in a recreational vehicle's wiring system to protect
all branch circuits.
2.5.4

AC Terminal Block Connections

The MSH3012RV has a six-pole AC terminal block and two AC ground terminals to connect the
inverter's AC input/output wiring. This terminal block (Figure 2-8) allows a service/distribution panel
(main panel) to be wired to the inverter's input, and also a dedicated panel (sub-panel) between
the inverter's output wiring and the AC loads. To access the AC terminal block and ground terminal,
remove the two Phillips screws holding the AC wiring access cover plate (Figure 1-3, Item 16).
Each AC terminal block connection can accept #18 to #4 AWG (.82 to 21.14 mm
Each connection uses a slotted screw, and the maximum tightening torque is 16 lbf-in (1.8 N-m).
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 prevent ground-loops (see Section 2.6.4 for more information).
The AC ground terminal can accept one #14 to #6 AWG (2.1 to 13.3 mm
slotted head screw and has a recommended maximum tightening torque of 45 in lbf (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.
