Basic Installation Procedures
AC Wiring and GFCIs
You can plug loads of up to 20 amps directly into the GFCI
receptacle on the front panel of the Freedom XC PRO. If installed,
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 XC PRO GFCI kit on the unit,
proceed to General AC Wiring Considerations on page 25.
AC wiring includes all the wires and connectors between the AC
source and the Freedom XC PRO and all wiring between the
inverter/charger, the AC panels, GFCI, and circuit breakers. The
type and size of the wiring varies with the installation and load. For
some RV applications, flexible multiple-strand copper wire is
required.
AC wiring must be sized appropriately using conductors with
insulation rated at least 75 °C 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 8 is based on the
U.S. National Electrical Code and the Canadian Electrical Code,
assuming two-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.

The AC input terminal is located inside the unit through the front
panel's ½" trade-size hole (or ¾" trade-size knockout) and is
labeled properly as AC IN or AC INPUT. The unit comes with
spring clamp-type terminals where individual wires can be
attached securely.
NOTICE
EQUIPMENT DAMAGE
Make sure the wires are connected properly. The AC wiring
terminal blocks are split into input and output sections.
Failure to follow these instructions can result in equipment
damage.
