Ac Output Wiring; Recommended Ground-Fault Circuit Interruption Breakers - Magnum Energy MM Series Installation And Operation Manual

2.0 Installation

AC Output Wiring

Caution: The inverter's AC output must never be connected
to an AC power source. This will cause severe damage to the
inverter and is not covered under warranty.
When hardwiring the output of the inverter, a cable will be need to be
routed from the inverter's output to an AC distribution panel (i.e. sub-
panel) that provides overcurrent protection to the loads powered by
the inverter. Connect the AC output to this distribution panel as
described below:
1. Remove the 1/2" knockout on the AC output connection (see figure
4, item 15) using a utility knife to cut through the round slot.
2. Discard this knockout and install a 1/2" strain-relief in the AC OUT
opening; you may need to file the opening edge to insert the strain-
relief.
3. Run a 2-conductor plus ground cable through the strain-relief on
the AC OUT opening. Refer to Table 4 for minimum wire size and
overcurrent protection required for the AC output wiring.
4. Remove about two inches of the insulating jacket from the AC
cable and separate the three wires and strip about 3/4" of insulation
from each wire.
5. Using approved AC wire connectors, connect the outgoing Hot Out,
Neutral Out and AC Ground wires to the MM Series AC wires colored
Red (HOT OUT), white with black stripe (NEU OUT) and green (AC
GROUND) respectively. Gently pull on the wires to ensure they are
securely held together and ensure no bare wire is exposed.
6. After making the AC output connections, secure the AC output
cable by tightening the strain relief.
7. Connect the outgoing AC wires to an AC load panel equipped with
overcurrent protection (i.e. circuit breakers).
The AC output wiring in the inverter should be complete, prior to
reattaching the AC access cover, review all AC wiring to ensure all
connections are correct and secure.

Recommended Ground-Fault Circuit Interruption Breakers

If installing this inverter in the wiring system of a Mobile application
(RV/Marine/Truck), a Ground-Fault Circuit-Interrupter (GFCI) must be
installed to protect all branch circuit powered by this inverter. In
addition, some electrical safety codes require GFCI's to be installed in
AE Applications (Home/Cabin/Office). In compliance with UL stan-
dards, Magnum Energy has tested the following GFCI's and find that
they function properly when connected to the inverter's AC output.
Shock Sentry
Leviton Smart Lock #8899-A
Hubbel #GF520EMBKA
Warning: Risk of electric shock. Use only the Ground-Fault
Circuit Interrupter [receptacles or circuit breaker(s)] speci-
fied in this manual. Other types may fail to operate properly
when connected to this inverter.
