Basic Installation Procedures

Step 4: Connecting the AC Input Wires

FIRE, SHOCK, AND ENERGY HAZARDS

Make sure wiring is disconnected from all electrical sources before handling. All wiring must be done in accordance with local and national electrical wiring codes. Do not connect the output terminals of the Freedom HF to any incoming AC source.

Failure to follow these instructions can result in death or serious injury.

General AC Wiring Considerations

AC Wiring Connectors Where applicable, connect AC wires with crimp-on splice connectors. The amount of insulation you strip off individual wires will be specified by the connector manufacturer and is different for different types of connectors.

AC and DC Wiring Separation Do not mix AC and DC wiring in the same conduit or panel. Where DC and AC wires must cross, make sure they do so at 90° to one another. Consult applicable codes for details about DC and AC wiring in close proximity to each other.

AC Wiring and GFCIs You can plug loads (12 amps continuous,

15 amps maximum) directly into the GFCI receptacle on the front panel of the Freedom HF. You can also connect the inverter to an existing AC installation and then plug loads into GFCI receptacles connected to that circuit.

If you plan to use the Freedom HF with the GFCI installed on the unit, proceed to “Step 6: Connecting the DC Cables” on page 21.

AC wiring includes all the wires and connectors between the AC source and the Freedom HF and all wiring between the inverter, the AC panels, circuit breakers, and the GFCIs. The type and size of the wiring varies with the installation and load. For some RV applications, flexible multiple-strand wire is required.

AC wiring must be sized appropriately to carry full load current on the input and output AC circuits in accordance with the electrical codes or regulations applicable to your installation. Table 4 is based on the U.S. National Electrical Code, 2003 Ed. and the Canadian Electrical Code, assuming 2-conductor-plus-ground cable, using 75 °C wiring, at an ambient temperature of 30 °C. Other codes and regulations may be applicable to your installation.
