Freedom XC PRO Owner's Guide
AC Shore Power
A source of 120 volts AC 60Hz sine wave alternating current
provides energy to pass power through to AC loads. This source
is usually the utility grid (power company) or an AC generator. An
automatic or manual AC source selector switch can be used to
switch between the multiple sources of shore power to the
Freedom XC PRO system.
The AC source feeding the Freedom XC PRO must have the
neutral conductor bonded to ground. When the inverter/charger
passes shore power through, it will lift its internal bonding relay on
the output and will rely on the input being bonded in order to ensure
that the power delivered to a sub panel is properly bonded. See
for more information on bonding relay
operation.
NOTE
: Throughout this guide, the term “shore power” refers to AC
input power from a utility grid, generator, or other AC source.
AC Disconnect and Over-Current
Protection Device
Most safety requirements and electrical codes require the
Freedom XC PRO’s AC and DC inputs and outputs to be provided
with over-current protection (such as circuit breakers or fuses) and
disconnect devices.
AC Input
The circuit breaker or fuse (connected through
hard wiring) that is used to supply the Freedom
XC PRO must be rated at no more than 30A (for
the Freedom XC PRO 2000) or 50A (for the
Freedom XC PRO 3000) and must be approved
for use on 120 volts AC branch circuits. The wire
used between the breaker and the Freedom XC
PRO input must be sized adequately to carry
current up to the rating of the input breaker and in
accordance with the electrical codes or
regulations applicable to your installation.
AC Output
The circuit breaker or fuse must be rated at no
more than the rating of the input breaker in the
installation and must be approved for use on
120 volts AC branch circuits. The wire used
between the Freedom XC PRO and the AC
output breaker must be of adequate size to
match the AC input circuit breaker’s rating. The
wiring from each AC output breaker to each of
the loads must be adequately sized to carry the
current rating of the individual AC output
breaker.
