INSTALLATION
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
Ground Lug
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
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.
WARNING
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.
