Grounding
For safety purposes, the chassis of the
inverter/charger must be connected to your
AC ground system. The chassis ground
bonding lug is located on the bottom of the
unit. This connector can accept two wires, the
first is used to connect the unit to AC ground,
the second can be used to connect other AC
equipment to the grounding system.
Use green insulated wire (8 AWG for
Freedom 10 and 6 AWG for Freedom 20, 25),
strip one end and use a screwdriver to secure
it to the chassis ground bonding lug. This wire
will connect to the ground in your AC
electrical system. Make sure the connection is
clean and tight.
This procedure will connect the chassis
of your unit to AC ground. In addition, the AC
input and AC output green wires are
connected to chassis ground. It is important to
connect these wires to the AC ground bus in
the circuit breaker panel.
Some installations require heavier
grounding wire. Conform to local and national
electrical codes. If in doubt, consult a
qualified electrician.
INSTALLATION
NOTE: Solar Applications: Use a 6
AWG green insulated or bare copper wire,
if no other equipment is grounded through
the unit. If additional equipment is con-
nected to the chassis grounding terminal,
larger wire may be required.
Strip one end of the wire and use a
screwdriver to secure it to the chassis
grounding terminal. This wire will connect
to the equipment ground system either at
the earth ground electrode or at an electri-
cal equipment enclosure ground bonding
terminal. In either case, you must insure
that the ground bonding wire does not be-
come smaller between the Freedom Combi
unit and the earth ground point.
More information on grounding can be
found in the National Electrical Code and
local electrical codes.
Note: The battery cables are not con-
nected to ground or the chassis of the unit.
For detailed installation suggestions,
refer to the separate Installation Guide.
Neutral Bonding
For safety purposes, the Freedom Combi
unit internally bonds the AC ouput neutral
(white) to the AC ground (green), when the
unit is OFF or in the inverter mode. When
incoming AC power is applied and the transfer
switch is engaged, the internal neutral-to-
ground bond is automatically lifted.
This means that when AC power
(shorepower) is applied, the grounding
system is connected to the shore power
ground, where neutral and earth ground are
