2.4.5 AC Output Wiring
CAUTION: The inverter’s AC output must never be con-
nected to an AC power source. This will cause severe
damage to the inverter and is not covered under warranty.
Info: When using the MMS Series inverter in an RV appli-
cation, under certain conditions and provided that the wire
is properly sized for the protecting breaker; RVIA wiring
standards will permit the breaker in the Main distribution
panel and/or the supplemental breakers on the inverter
to provide adequate protection for the AC output wiring.
For more information on these requirements, refer to the
RVIA (www.rvia.org).
Follow the steps below to hardwire the AC output of the MMS Series
inverter:
1. Remove the 1/2” knockout on the AC Output Connection
(Figure 3, Item 9)—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 for proper fi t.
3. Run a 2-conductor plus ground cable through the strain relief in
the AC OUT opening. Refer to Table 4 for the minimum wire size
and the overcurrent protection required for the AC output wiring.
4. Remove about two inches (5.1 cm) of the insulating jacket from
the AC cable, and then separate the three wires and strip about
3/4” (1.9 cm) of insulation from each wire.
5. Using approved AC wire connectors, connect the outgoing Hot
Out, Neutral Out, and AC Ground wires to the inverter’s AC wires
colored red (HOT OUT), white with black stripe (NEUT 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 either:
a) an AC load sub-panel equipped with overcurrent protection
(e.g., circuit breakers), or
b) directly to the circuit (if following RVIA requirements that
permit using breakers from the main distribution panel or the
breakers on the inverter under certain conditions).
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.
