4. Allow 13 cm (minimum) of clearance around the unit and allow for a supply
of fresh air to the cooling fan. Do not block any of the vents or louvers. The
fan pulls air from outside the unit. It blows the air across the internal
components, particularly the transformer and heat sinks, then out the side
vents.
5. The mounting location should be as close to the batteries as possible. The
battery cables can be extended, however each cable must not be over 3.04 m
in total length from the inverter to the battery terminals.
Grounding
For safety purposes, the chassis of the Freedom 10 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 ground.
Use 5.0 mm
2
ES (Euro Standard) green insulated wire. 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 Freedom 10 to AC ground. In
addition, the AC input and AC output green/yellow wires are connected to chassis
ground. It is important to connect these wires to the AC ground bus in the circuit
breaker panel.
Please note that the battery cables are not connected to ground or the chassis of the
Freedom 10.
Neutral Bonding
For safety purposes, the Freedom 10 internally bonds the blue AC output neutral
wire to the green/yellow AC ground wire 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 the boat is in a marina, the grounding system is connected
to the shore power ground, where neutral and earth ground are bonded together.
This technique ensures safety and conforms to the requirements of numerous
electrical codes.
Refer to other applicable electrical codes regarding connections between AC
ground and DC ground for marine applications.
WARNING: Fire hazard
Do not mount the unit in a gasoline powered engine compartment or in an enclosed battery
compartment. Diesel engine compartments are acceptable locations, but take
precautions to keep dirt and spray off the unit.
