Freedom SW-RVC Installation Guide
Some conditions for Freedom SW-RVC:
n
If the input wiring is split-phase, the output
wiring must be sized to coordinate with the
breakers used on the input. Refer to your
applicable installation codes.
n
If the input wiring is dual-input and the output
wiring is single-input, the following rules
apply: If the input breaker on L1 is greater
than 25 amps, the wire size must be
coordinated for that amperage. If the input
breaker on L1 is less than 25 amps, the wire
size must be coordinated for 25 amps. The
wire size must not be sized for anything
lower than 25 amps.
n
If both the input and the output wiring are
dual-input, the output wiring for each line (L1
and L2) must be calculated separately,
following these rules: If the input breaker on
the specific line is greater than 25 amps, the
wire size for that line and its neutral must be
coordinated for that amperage. If the input
breaker on the specific line is less than 25
amps, the wire size for that line and its
neutral must be coordinated for 25 amps.
The wire size must not be sized for anything
lower than 25 amps.
Size of Wiring Downstream of the AC Output
Breaker
The wiring used between the AC output breaker
and your loads must be sized to match the output
breaker.
AC Output
Neutral
Bonding
The AC source must have its neutral conductor
bonded to ground.
Bonding system
The Freedom SW-RVC provides a system that
automatically connects the neutral conductor of the
inverters AC output circuit to safety ground
(“bonding” it) while the inverter/charger is inverting,
and disconnects it (“unbonding” it) when the
inverter/charger is connected to external AC
power. This system is designed to conform to
installation codes that require AC sources such as
inverters and generators to have their neutral
conductors tied to ground at the source of power in
the same way that the neutral conductor from the
utility is tied to ground. These same codes specify
that the neutral can only be connected to ground in
one place at any one time.
