Thank you for purchasing a Heart Interface Freedom 458 Series Combi Charger. Heart Interface takes pride in manufacturing quality products specifically designed to meet your power requirements. Freedom Combi Inverter/Chargers provide silent, efficient and reliable AC power for a variety of applications. They feature “hands-free” operation, automatic 3-stage battery charging and automatic AC transfer switching.
• The inverter provides regulated 120 volt AC power at a crystal controlled frequency from a deep cycle battery bank and is rated at: Freedom 15 & 15D 1500 watts Freedom 20 & 20D 2000 watts The output is a modified sine wave and is compatible with most appliances, tools and other 120 VAC equipment.
Voltage shut down also occurs for a high battery condition at 15.5 volts. Operation will resume automatically when the battery voltage OUT 2 drops below 15.5 volts. Check all DC sources on the system for the reason for the excessive voltage. Power Sharing...
THINGS YOU SHOULD KNOW Temperature Sensitive Charging When the supplied battery temperature sensor is connected to the unit and the batteries, the charge voltage is controlled based on battery temperature. The charger adjusts the charge voltage to the best level, minimizing water loss in wet cell batteries.
The Freedom Inverter/Charger provides 120 volt AC power from auxiliary DC batteries, automatic battery charging and automatic AC transfer switching between an external AC source and inverter mode. External AC Power When external AC power is available, the 3-stage battery charger, transfer switching, and Power Sharing automatically function.
• When the LED is solid red, it indicates a battery warning condition, the battery voltage is below 10.5 volts DC or above 15.0 volts DC. • When the LED is blinking slowly, (1 time per second), a battery shutdown has occurred.

LOW BATTERY & OVERTEMP/OVERLOAD - Red LEDs • When both LEDs are blinking, an AC backfeed has been detected. A backfeed occurs when AC power from an external source is connected to the output of the inverter. Inspect wiring for possible input/output wiring error.
OPTIONAL REMOTE CONTROL PANELS Remote Control Panel An optional remote control panel is available. The LED bargraphs on the remote control panel shows battery voltage and DC current in both inverter and charger modes. Easy to see red, yellow and green LEDs show the battery state-of-charge.
BATTERY TYPES Use only deep-cycle batteries with your Freedom Inverter/Charger. These fall into three broad categories: wet cell, gel cell and Advanced AGM (Absorbed Glass Mat) batteries. Wet Cell Batteries True deep-cycle wet cell batteries are characterized by relatively thick internal plates that are alloyed with antimony.
BATTERIES Beware of so-called maintenance-free batteries. These batteries have calcium alloyed with the lead and hold the liquid electrolyte in a sponge-like material. They are sealed and water can not be added. Do not confuse them with true gel cell or AGM batteries, they will not hold up well to deep discharging and repeated cycling.
Parallel Connecting two batteries in parallel will double the Amp-hour rating of the battery bank, while the voltage will be the same as each individual battery. Example, two 12 volt 105 Amp-hour batteries in parallel will produce one 12 volt 210 Amp-hour battery bank. Parallel Parallel Increase Amp-hour Capacity 12V INVERTER...

BATTERIES To achieve 50% cycling you should calculate your Amp-hour consumption between charging cycles and use a battery bank with twice that capacity**. Each AC appliance or tool has a rating plate on it and will be rated in either AC Amps or Watts or AC VA (Volt-Amps) apparent power.
Battery Charging Completely charging wet cell deep-cycle batteries requires the battery voltage to be raised beyond what is known as the gassing point. This is the voltage at which the battery begins to bubble and gas is given off. If charging stops short of this point, sulfate is left on the plates and deterioration of the battery begins.

BATTERY CHARGING NOTE: Freedom battery chargers are ON whenever AC power is connected to the charger input. The charger can be turned OFF using the CHARGE switch on the front of the unit. This sequence will occur each time external AC power is available. The charger can be turned ON/OFF using the Remote Control Panel or Link Instrumentation.

A timer will terminate the acceptance stage if this current level is not reached. ACCEPTANCE TO FLOAT TRANSITION POINTS Freedom 15 & 15D 10 Ampere DC Freedom 20 & 20D 15 Ampere DC Maximum acceptance time is 1 hour for wet and AGM cells and 3 hours for gel cells.

BATTERY CHARGING The equalizing charge is a timed, 8-hour cycle. The cycle can be ended early by inter- rupting the AC power to the charger at any time during the cycle. Equalizing should only be engaged after the batteries have been fully charged by a normal battery charging cycle.
Page 19
WARNINGS 1. Do not equalize gel cell batteries. Check remote default settings. 2. Always monitor the equalize charge cycle. Provide proper ventilation for battery fumes. Do not allow any sparks during equalizing. If one or more cells begin to overflow, terminate the equalize cycle.
BATTERY CHARGER VOLTAGE SETTINGS l l e F ° ° * There are two gel battery settings. Check with the battery manufacturer to determine the proper setting for your batteries. Usually, Gel 1 is for long battery life; Gel 2 is for rapid charging. **Default setting when the temperature sensor is not connected.
Part No. 90-0123-00 Libertycombi.p65 10/26/98 Confirm that your shipping carton contains: • Inverter/Charger • TSC temperature sensor with 15’ cable • Owners Manual • Warranty Card • Jumper for AUX Switch (only used without Remote Control Panel or Link Instrument) •...
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.
Part No. 90-0123-00 Libertycombi.p65 10/26/98 INSTALLATION two places with a pressure of 15 tons using a hexagonal die. The T&B die has a code number of 54. After the crimp is made, the barrel of the terminal and the first inch of the cable needs to be covered in UL Listed or UL Recognized heat shrink tubing.
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.
20 ampere branch circuit rated breaker. This also applies to Dual Input models where the inputs may be 20 amperes each. In Canada, 15 ampere branch circuit(s) maximum shall provide the service. If a 30 ampere service supplies the...
If installing the TSC (Temperature Sensitive Charging) sensor, connect the ring terminal end to the positive battery post, complete the routing of the RJ11 cable (15 feet supplied) and connect the plug end to the TSC jack on the front of the unit...
• Remove the positive (+) battery cable terminal cover from the unit and attach the battery cable. Tighten the battery terminal bolts to a torque value between 160 inch-pounds and 180 inch-pounds. Replace the cover for the positive terminal. The negative (-) cable should be connected directly to the negative post of the house or auxiliary battery bank or the ground side of a current shunt.

3. Check the battery voltage and ensure it is within proper range for the unit (10-15.5 VDC). 4. Install the jumper in the Auxiliary Switch port (AUX SWITCH), if using the in- verter without remote.
INSTALLATION • Testing for backfeed. If a backfeed condition is indicated, disconnect from shore power and disconnect the AC output wires on the inverter. Make sure the inverter is OFF. Apply shore power and measure for voltage between the black and white wires that were attached to the inverter output feeding the electrical panel or loads, not the inverter output wires.
Alternating Current (AC) An electric current that reverses direction at regular intervals. Sources of alternating current are shore power, generator power, inverter power or household current. Ampere (Amp, A) The unit of measure of electron flow rate of current through a circuit. Ampere-hour (Amp-Hr., AH) A unit of measure for a battery’s electrical storage capacity, obtained by multiplying the current in...
