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 XC. 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 XC'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.

AC Output Neutral Bonding Option (Earth
Relay Function)
The earth relay function allows you to connect the neutral
conductor (N) of the inverter output circuit to the safety earth
(G / PE) automatically when the inverter/charger is working in
battery mode. Refer to local code and standards for more details.
In order to enable the earth relay function, you must install the
bonding screw. Check the regulations for your specific application
to ensure that the installation will comply with the necessary
requirements.
To install the bonding screw:

1. Look for the bonding screw provided inside the bag with the
Owner's Guide.
2. On the left side panel of the unit near the AC and DC
terminal openings, remove the round sticker covering the AC
Out Neutral-to-Earth Bond hole.
