INSTALLATION

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.

WARNING

Do not mount the unit in an enclosed battery compartment. Take precautions to keep dirt and spray off the unit.

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.

WARNING

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.
