4. Remove about two inches of the insulating jacket from the AC
cable, and then 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-AE 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 check to see that 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 (e.g., circuit breakers).
The AC output wiring in the inverter should be complete. Before
reattaching the AC access cover, review all AC wiring to ensure all
connections are correct and secure.
Ground-Fault Circuit Interruption (GFCI) Breakers
Some electrical safety codes require GFCI’s to be installed in AE
applications (home/cabin/offi ce). In compliance with UL standards,
Magnum Energy has tested the following GFCIs and fi nd that they
function properly when connected to the inverter’s AC output.
Shock Sentry TM #XGF15V-SP
Leviton Smart Lock #8899-A
Hubbel #GF520EMBKA
WARNING: Risk of electric shock. Use only the GF-
CIs [receptacles or circuit breaker(s)] specifi ed in this
manual. Other types may fail to operate properly when
connected to this inverter.
Functional Test
After all electrical connections to the inverter, batteries, AC source,
and loads (using a sub-panel) have been completed, follow these
steps to test the installation and the inverter’s operation.
1. Check the battery voltage and polarity before connecting the
batteries to the inverter. Use a multimeter to verify 10 to 14 VDC
(12-volt models) or 20 to 28 VDC (24-volt models) at the batteries’
positive and negative terminals.
2. Apply battery power to the inverter by switching the DC disconnect
ON (or close the DC circuit-breaker). The inverter will remain OFF,
but the green status indicator on the front of the inverter will quickly
blink once to indicate that DC power has been connected and is ready
to be turned on.
