Wiring the Inverter/Charger975-0209-01-01 2–5AC WiringOverview The U.S. National Electrical Code (NEC) defines the standards for AC and DCinstallation wiring in RV applications, but there are still many installationvariables. Most are determined by the level of automatic switching desired and theamount of external AC power to be switched.Installation should be done by a qualified electrician. Consult local code for theproper wire sizes, connectors and conduit.The AC and DC terminals are located on the same end of the chassis as the statusLED and power switch. A six station terminal block is provided to connect the ACinput and AC output. All terminals are labeled on the inverter. Consult your localcode for proper wire sizes, connectors, conduit, and so on. See Table 2-1 forminimum recommended wire sizing. Code requires that an external disconnectswitch be used in the AC input wiring circuit. The AC breakers in a sub panel willmeet this requirement.Figure 2-1 RV Electrical System DiagramImportant: Figure 2-1 does not show all required grounding or over-current protection.GeneratorIsolatorNon-Inverter LoadsEngine BatteryGFCITransfer SwitchAC Main PanelAC In AC OutUtilityPowerInverter AC PanelAlternatorTEST MONTHLYRESET RESETTEST TESTRC/GS Remote/RV Series Inverter/ChargerPN 270-0697-01-013060A30ADC +DC -DC FuseHouse BatteryBattery TemperatureSensorEngine Negative TerminalSensing and controlDC Load CenterGrounding (Bonding) BusDC Negative Grounding BusDC Positive Bus+
