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):
