Basic Installation Procedures
This guide for use by qualified installers only.
Step 2: Choosing a Location for the Unit
The Freedom HF should only be installed in locations that meet the
following requirements:
❐ Dry. Do not allow water or other fluids to drip or splash on the
Freedom HF. Do not mount the Freedom HF in an area subject to
splashing water or bilge water.
❐ Cool. Normal air temperature should be between 32 °F and 104 °F
(0 °C and 40 °C)—the cooler the better.
❐ Ventilated. Allow at least 5 in. (13cm) of clearance at the DC end of
the Freedom HF for air flow, 1 in. (2.5cm) on each side, and 2 in.
(5cm) at the AC end. The more clearance for ventilation around the
unit, the better the performance. Do not allow the ventilation openings
on the ends of the unit to become obstructed.
❐ Safe. Do not install the Freedom HF in the same compartment as
batteries or in any compartment capable of storing flammable liquids
like gasoline.
❐ Close to the battery compartment and the AC source and load
panels. Avoid excessive cable lengths (which reduce input and output
power due to wire resistance). Use the recommended cable lengths and
sizes, especially between the battery banks and the Freedom HF.
❐ Protected from battery acid and gases. Never allow battery acid to
drip on the Freedom HF or its wiring when reading specific gravity or
filling the battery. Also do not mount the unit where it will be exposed
to gases produced by the batteries. These gases are very corrosive, and
prolonged exposure will damage the Freedom HF.
FIRE AND EXPLOSION HAZARDS
• This equipment contains components that tend to produce arcs or
sparks. To prevent fire or explosion, do not install the Freedom HF in
compartments containing batteries or flammable materials, or in
locations that require ignition-protected equipment. This includes any
space containing gasoline-powered machinery, fuel tanks, or joints,
fittings, or other connections between components of the fuel system.
• To reduce the risk of fire, do not cover or obstruct the ventilation
openings. Do not install the Freedom HF in a zero-clearance
compartment. Overheating may result.
Failure to follow these instructions can result in death or serious
injury.
