Grounding
For safety purposes, the chassis of the
inverter/charger must be connected to your AC
ground system. Use 8 AWG bare copper or
green insulated wire, strip one end and use a
screwdriver to secure it to the chassis ground
bonding lug on the side of the unit. This wire
will connect to the ground in your AC electrical
system. Make sure the connection is clean and
tight.
The system AC ground compression
terminal blocks are shipped in the accessory
packet. These may be used to make the
connections in the wiring compartment. This
terminal block is for the bare copper or
green ground wires from the AC branch circuit
supply and to the AC loads or distribution
panel. It is important that these AC input and
AC output ground wires also connect to the AC
ground bus in the circuit breaker panels. The
compression terminal blocks are labeled
Ground/green ( ), Neutral/white (N), Hot or
Line/black (L).
Some installations require heavier chassis
grounding wire. Refer to local and national
electrical codes.
Note:
For additional information on
grounding refer to American Boat and Yacht
Council (ABYC) recommendation A-25.6.
Refer to page 33.
INSTALLATION
Note: The battery cables are not
connected to the chassis lug of the unit.
Neutral Bonding
For safety purposes and NEC code
requirements, the Freedom Combi unit
internally bonds the AC output neutral (white)
to the AC output 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.
When external AC power is applied, the
grounding system is connected to the source
power ground, where neutral and earth ground
are bonded together. This technique ensures
safety in all conditions and conforms to the
requirements of the NEC.
Do not connect incoming AC from any
source to the AC output of the inverter/
charger. This is known as backfeeding and
will damage the unit and void the warranty.
The Over Temp/Overload and Low Battery
LEDs will be blinking rapidly if this
condition exists.
