8 Freedom Xi Installation Guide
Basic Installation Procedures
AC Distribution Panels
Most systems incorporate distribution centers both ahead of the
Freedom Xi (the AC source panel) and between the Freedom Xi and
the loads (the AC load panel). An AC source panel includes a main
circuit breaker, which serves as over-current protection and as a
disconnect for the AC shore power supply line. Additional circuit
breakers serve individual circuits, one of which serves the Freedom
Xi. The AC load panel can incorporate an AC output circuit breaker
and breakers for individual load circuits.
AC Cabling
AC cabling includes all the wires and connectors between the AC
source and the Freedom Xi, as well as all cabling between the
Freedom Xi and the AC output panels, circuit breakers, and loads.
The type and size of the wiring varies with the installation and load.
For example, in high vibration environments, such as marine or RV
applications, wire nuts may not be acceptable, so crimp splices
would be required. In other applications, flexible multiple-strand
wire may be required. Installation codes usually specify solid or
stranded, overall size of the conductors, and type and temperature
rating of the insulation around the wire.
AC breakers and fuses must be sized to adequately protect
the
wiring that is installed on the input and output AC circuits of the
Freedom Xi. All breakers and wiring must be sized and connected
in accordance with the electrical codes or regulations applicable to
your installation. Table 1 gives some examples of wiring sizes based
on the U.S. National Electrical Code and the
Canadian Electrical
Code. These examples are based on using a two-conductor-plus-
ground cable rated at 75 °C, and assuming an ambient temperature
of up to 30 °C. Ensure that your breakers and fuses have suitable
temperature ratings for your wiring. Other codes and regulations
may also be applicable to your installation.

NOTICE
RISK OF DAMAGE TO THE INVERTER
Do not connect the Freedom Xi to a 120/240V, 3-pole, 4-wire circuit.
Failure to follow these instructions can damage the unit and/or equipment.
