Recommended GFCI (Ground Fault Circuit Interruption) Outlets

Some electrical safety codes require the use of GFCI's. In compliance with UL standards, Magnum
Energy has tested the following GFCI's and fi nd that they function properly when connected to
the inverter's AC output:
Shock Sentry
#XGF15V-SP •
TM
CAUTION: GFCIs shall be installed in a recreational vehicle's wiring system to protect
all branch circuits.

AC Terminal Block Connections

The MSH-M Series models have a four-pole AC terminal block and an AC ground terminal to connect
the inverter's AC input and output wiring. This terminal block (see Figure 2-8) 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
) CU stranded wire, or two #12 AWG (3.3 mm
2
M3.5 slotted head screw, and the maximum tightening torque is 16 in lbf (1.8 Nm).
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 NEUTRAL IN and NEUTRAL 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 2.6.5 for more information).
If the installation requires the input and output neutrals to be connected together, the
inverter's neutral-to-ground connection must be disconnected (see Section 2.6.5).
The AC ground terminal can accept one #14 to #6 AWG (2.1 to 13.3 mm
uses a slotted head screw and has a recommended maximum tightening torque of 45 in lbf (5.1
N-m).
