1.0 Introduction

The MS-GFCI accessory allows a GFCI (Ground Fault Circuit Interrupter) recep-
tacle to be installed directly on a Magnum inverter. This accessory includes a
duplex GFCI 20-amp rated outlet that can be easily wired and attached to the
right side of the inverter. The GFCI outlet quickly stops the flow of electricity in
the event a ground fault occurs on the device that is plugged into the inverter.

A GFCI receptacle does NOT protect against circuit overloads, short circuits,
or shocks; therefore, the MS-GFCI accessory can only be safely installed
on a Magnum inverter that includes output branch-rated circuit protection.
This integral output circuit protection is only available on Magnum Energy’s
MS2000-20B or MS2012-20B inverter/charger models.

2.0 Installation

The following pertains to attaching the GFCI accessory to the MS2000-20B
or MS2012-20B inverter/charger models.

WARNING: Installing the MS-GFCI accessory on an inverter with-
out integral output circuit protection (i.e., not a -20B model) may
cause the wires to overheat and cause a fi re.

WARNING: Installations should be performed by personnel that
understand basic wiring principles and techniques, can interpret
wiring diagrams, have circuit wiring experience, and are prepared
to take a few minutes to test their work to ensure the GFCI recep-
tacle is wired correctly.

WARNING: Before proceeding — to prevent accidental shock — do
not
touch any parts inside the inverter until all sources of power to
the inverter are de-energized (i.e., breakers open, fuses removed).
This includes all DC power (i.e., batteries, solar, wind or hydro)
and AC power (utility power or AC generator). Use a voltmeter to
ensure all power has been removed.

2.1 Tools Required

To install the GFCI outlet panel you will need:

Flat blade screwdriver

Phillips screwdriver

AC voltmeter

Test lamp (rated at 120 VAC)

2.2 Attaching the GFCI to the Inverter

To wire the GFCI outlet to the inverter, follow these steps:

1. Remove the two Phillips screws (#8-32) that hold the existing AC access

panel to the inverter (retain for attaching the GFCI outlet panel).

2. Connect the voltmeter between the AC HOT 1 OUT and the AC NEUT OUT

terminals/wires. Ensure there is no voltage present on any terminals/
wires.

3. Connect the GFCI outlet’s 3 pre-stripped wires as follows (refer to

Figure 1 for MS2012-20B models, or Figure 2 for MS2000-20B models):
