© 2010 Magnum Energy, Inc.2.0 Installation24AC Output WiringCAUTION: The inverter’s AC output must never be con-nected to an AC power source. This will cause severedamage to the inverter and is not covered under war-ranty.Info: When using the MMS Series inverter in an RV ap-plication, under certain conditions and provided that thewire is properly sized for the protecting breaker; RVIAwiring standards will permit the breaker in the Main dis-tribution panel and/or the supplemental breakers on theinverter to provide adequate protection for the AC outputwiring. For more information on these requirements, referto the RVIA (www.rvia.org).Follow the steps below to hardwire the AC output of the MMS Seriesinverter:1. Remove the 1/2” knockout on the AC Output Connection (see Figure3, 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 OUTopening. You may need to file the opening edge for proper fit.3. Run a 2-conductor plus ground cable through the strain relief inthe AC OUT opening. Refer to Table 4 for the minimum wire size andthe overcurrent protection required for the AC output wiring.4. Remove about two inches of the insulating jacket from the ACcable, and then separate the three wires and strip about 3/4” ofinsulation from each wire.5. Using approved AC wire connectors, connect the outgoing HotOut, Neutral Out, and AC Ground wires to the inverter’s AC wirescolored red (HOT OUT), white with black stripe (NEU OUT), andgreen (AC GROUND) respectively. Gently pull on the wires to ensurethey are securely held together, and check to see that no bare wireis exposed.6. After making the AC output connections, secure the AC outputcable 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), orb. directly to the circuit, when following RVIA requirements thatpermit using breakers from the main distribution panel or thebreakers on the inverter under certain conditions.The AC output wiring in the inverter should be complete. Beforereattaching the AC access cover, review all AC wiring to ensure allconnections are correct and secure.
