Installation Manual

2.0 Installation

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

#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.
