AC Output Wiring

CAUTION: The inverter's AC output must never be con-
nected to an AC power source. This will cause severe dam-
age to the inverter and is not covered under warranty.
When hardwiring the output of the inverter, a cable must be routed
from the inverter's output to an AC distribution panel (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) – use a utility knife to cut thru the round slot.
2. Discard this knockout and install a 1/2" strain relief in the AC OUT
opening. You may need to fi le the opening edge to fi t properly.
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 overcur-
rent protection required for the AC output wiring.
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 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 reat-
taching the AC access cover, review all AC wiring to ensure all connec-
tions are correct and secure.
Ground-Fault Circuit Interruption (GFCI) Breakers
If installing this inverter in the wiring system of a mobile application
(RV/marine/truck), a GFCI may be installed to protect some branch
circuits powered by this inverter. 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
Leviton Smart Lock #8899-A
Hubbel #GF520EMBKA
WARNING: Risk of electric shock. Use only the GFCIs
[receptacles or circuit breaker(s)] specifi ed in this manual.
Other types may fail to operate properly when connected
to this inverter.
