© 2010 Magnum Energy, Inc. 212.0 InstallationThe AC wires inside the AC compartment are #16 AWG with a tem-perature rating of 105° C. All AC connections should be made usingan approved connector for your application (e.g., split bolt, twist-onwire connectors, etc.). Ensure the wire connectors used are rated forthe size and number of wires you are connecting.After connecting the wires together, gently pull on the wires to ensurethey are securely held together. In a proper connection, no bare wireshould be exposed.Info: Per UL certification, non-metallic sheathed cable(i.e., Romex™) or an SO flexible cord with listed strainreliefs are allowed to be used to connect to the inverter;conduit connections are not allowed.After all AC wiring in the inverter is complete (and before reattachingthe AC access cover), ensure all connections are correct and secure.Wire color (label) Wire connectionBlack (HOT IN) Hot InWhite (NEUT IN) Neutral InRed (HOT OUT) Hot OutWhite with blackstripe (NEUT OUT) Neutral OutAC Ground Green (GROUND) AC IN and AC OUT GroundAC INAC OUTTable 3, Wire Color to AC Wire ConnectionAC Wiring ConnectionsFor the MMS1012 model, the AC input and output wiring is performedin the AC wiring compartment. This compartment is accessed viathe top panel (see Figure 3, Item 8). If the panel cover is installed,remove the two Phillips screws on the cover to access the AC wiringcompartment and locate the inverter’s AC wiring. There is a labellocated in the AC access compartment which gives information onwhich wires are used for AC input and output. You can also refer toTable 3 to match the inverter’s AC wires to the appropriate AC wireconnection.AC Wire Size and Overcurrent ProtectionThe AC input and output wiring must be sized per the NEC and localelectrical safety code requirements to ensure the wire’s ability tosafely handle the inverter’s maximum load current. After determiningthe proper AC wire sizes, the inverter’s AC input (unless you are usinga flexible cord) and output wires are required to be protected againstovercurrent and have a means to disconnect the AC circuits.
