CAUTION Risk of electrical shock. Do not
remove cover, no user serviceable parts
inside. Refer servicing to qualified service
personnel.
The Freedom Combi is appropriate for
installation in recreational vehicles (RV), and
other applications.
It is recommended that installation be
completed by an authorized Heart Interface
technical dealer or experienced electrician.
Key Installation Points
1. The unit is designed to mount
horizontally (on a shelf).
2. Allow several inches of clearance around
the unit to permit a supply of fresh air to the
cooling fan. Do not block any of the vents or
louvers. The thermostat controlled fan pulls air
from outside the unit. It pulls air across the
internal components, particularly the trans-
former and heat sinks, then out the fan vent.
3. Keep the inverter/charger out of the
elements and out of direct contact with
water or spray. Failure to do so may result in
premature malfunction from corrosion and void
the warranty.
4. Mount the unit as close to the batteries
as possible but not in the presence of
flammable fumes or in an enclosed battery
compartment.
INSTALLATION
5. Keep the overall length of each battery
cable less than 10 feet. Do not use frame
ground or a ground bonding system as a
current carrying conductor. Run the negative(-)
cable directly to the battery bank. If the positive
(+) and negative (-) cables run parallel to each
other, twist the cables together. This will
minimize the inductive adverse effects of cable
length. Be sure the cable size meets with NEC
requirements for your installation.
6. Make sure all wiring conforms to local
and national electrical codes. If in doubt,
consult with a qualified electrician.
7. To meet electrical codes, a UL Listed DC
Rated slow blow fuse must be installed in the
positive battery cable within 18 inches of the
battery post. This fuse is intended to protect
the battery and cables against a short circuit.
The inverter is protected internally and will not
blow a properly sized fuse.
8. Do not connect the battery until you
have read the remainder of the installation
section. Observe proper polarity when
connecting batteries. Reverse DC polarity will
result in damage to the unit and will void the
warranty. Use care when making the DC
connections.
The Freedom Series is not DC reverse
polarity protected. Be very careful to
connect the negative and positive cables
correctly, otherwise damage will result and
the warranty will be void.
WARNING
Do not mount the unit in an enclosed
battery compartment. Take precautions to
keep dirt and spray off the unit.
