Basic Installation Procedures
16 Freedom X 2000 - 230V Owner's Guide
AC Distribution Panels
Most systems incorporate distribution centers both ahead of the
Freedom X (the AC mains panel) and between the Freedom X and
the loads (the AC load panel). An AC mains panel includes a main
circuit breaker, which serves as over-current protection and as a
disconnect for the AC mains power supply line. Additional circuit
breakers serve individual circuits, one of which serves the
Freedom X. 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
mains and the Freedom X, as well as all AC cabling between the
Freedom X 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 X. All breakers and wiring must be sized and connected
in accordance with the electrical codes or regulations applicable to
your installation.
Table 4 gives some examples of wiring sizes.
These examples are based on using a two-conductor-plus-earth
copper cable rated at 60 ° 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.

AC Output Neutral Floating
By default, the neutral conductor of the Freedom X’s AC output
circuit (that is, AC Output Neutral) is left floating, meaning
isolated from earth potential. When AC utility power is present this
connection is not present, so that the utility neutral (that is, AC
Input Neutral) is only connected to utility earth at your source.
Check the regulations for your specific application to ensure that
the installation will comply with the necessary requirements.
