Safety

Explosive gas precautions

WARNING: Explosion hazard

1. Working in the vicinity of lead-acid batteries is dangerous. Batteries generate explosive gases during normal operation. Therefore, you must read this guide and follow the instructions exactly before installing or using your Freedom 10 Inverter/Charger.

2. This equipment contains components that tend to produce arcs or sparks. To prevent fire or explosion, do not install the Freedom 10 Inverter/Charger 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, as well as joints, fittings, or other connections between components of the fuel sys t em .

3. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

Precautions When Working With Batteries

WARNING: Explosion or fire hazard

1. Follow all instructions published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

2. Make sure the area around the battery is well ventilated.

3. Never smoke or allow a spark or flame near the engine or batteries.

4. Use caution to reduce the risk or dropping a metal tool on the battery. It could spark or short circuit the battery or other electrical parts and could cause an explosion.

5. Remove all metal items, like rings, bracelets, and watches when working with lead-acid batteries. Lead-acid batteries produce a short circuit current high enough to weld metal to skin, causing a severe burn.

6. Have someone within range of your voice or close enough to come to your aid when you work near a lead-acid battery.

7. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

vi 975-0251-01-01

8. Wear complete eye protection and clothing protection. Avoid touching your eyes while working near batteries.

9. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.

10. If you need to remove a battery, always remove the ground terminal from the battery first. Make sure all accessories are off so you don’t cause a spark.

Precautions for Using Rechargeable Appliances

CAUTION: Equipment damage

Most rechargeable battery-operated equipment uses a separate charger or transformer that is plugged into an AC receptacle and produces a low voltage charging output.

Some chargers for small rechargeable batteries can be damaged if connected to the Freedom 10 Inverter/Charger. Do not use the following with the Freedom 10 Inverter/Charger:

Safety

• Small battery-operated appliances like flashlights, razors, and night lights that can be plugged directly into an AC receptacle to recharge.

• Some chargers for battery packs used in power hand tools. These affected chargers display a warning label stating that dangerous voltages are present at the battery terminals.

Important:

Introduction

Chapter 1 describes the features and functions of the Freedom 10 Inverter/Charger.

Introduction

This Owner’s Manual describes the Xantrex Freedom 10 Inverter/Charger. This unit performs four distinct functions:

1. DC to AC power inverting

2. Automatic transfer switching between inverter power and incoming AC power

3. Three-stage automatic battery charging plus manual battery equalizing

4. AC to DC power converter.

The inverter provides 1,000 watts of voltage and frequency-regulated AC power from a deep-cycle battery bank. The output is a modified sine wave and is compatible with virtually all consumer appliances. An idle circuit reduces battery power consumption when the inverter is unloaded. There is a low battery cutout circuit and considerable momentary surge power is available for starting electric motors. High efficiency ensures the longest possible battery life between recharges.

Hardware Included.

Figure 1-1

Transfer switch The transfer switch allows the Freedom 10 to be connected to an external AC

source. Some of the external AC power is used to operate the battery charger, the rest is switched through the unit to the output. Thus, the Freedom 10 operates as a self-contained backup power system just by adding batteries. The power sharing feature constantly senses the AC current being used by the battery charger and the appliances connected to the output, and automatically reduces battery charger power consumption if usage exceeds the input circuit breaker rating.

Battery charging The Freedom 10 battery charger is electronically controlled and rated at

50 amps DC (25 amps DC for 24-volt systems). It is designed to rapidly and optimally recharge either wet or gel cell deep-cycle batteries. Battery charging is accomplished in three automatic stages: Bulk Charge, Acceptance, and Float Charge. In addition, using the remote control, a manually engaged equalizing charge cycle is poss ible.

Freedom 10 Inverter/Charger

Things You Should Know

DC power supply With an external AC source connected, the Freedom 10 charger also serves the

functions of an AC to DC converter to supply all of the DC loads that are connected to the battery.

Simple, automatic operation is made possible by the microprocessor that is the brain of the Freedom 10. In most cases, the unit is left on and no attention or maintenance is required.

Optional remote panel

Two optional remote control panels are available for the Freedom 10—one for 12 V models and one for 24 V models. These remote control panels provide a power switch, system status LEDs, DC volts and DC amps LED bar graphs. In addition, the remote control panel allows adjustment of the following settings:

• three-stage or equalize charging

• temperature

• battery type

• charger mode

• idle sensitivity

•power sharing.

Things You Should Know

WARNING: Unexpected operation

A transfer between inverter and charge modes of operation may temporarily take place when the product is subjected to electrostatic discharge.

Intended Use

The Freedom 10 Inverter/Charger is intended:

• as a DC to AC inverter/battery charger

• for use in recreational vehicles, recreational marine vehicles, and residential solar applications

• to be permanently installed, not portable

• to be used with a DC fuse as described in the installation section of this manual.

Circuit Breaker Protection

The 15 amp circuit breaker on the front of the unit protects against sustained inverter overloads. The breaker is reset by pressing the button. The 15 amp circuit breaker protects the incoming AC circuit which is transferred through to the loads, and feeds the battery charger.

975-0251-01-01 1–3

Introduction

Electronic Protection

Fast-acting electronic circuits protect the inverter from extreme overloads, low and high battery voltage and over-temperature. They can be reset by cycling the power switch off and on. The fault condition must be eliminated before reset will occur. For example, remove the overload, recharge the batteries, or allow the unit to cool. See “Troubleshooting” on page 4–1.

Inverter ldle Circuit

The inverter idle circuit is an automatic energy saving feature that reduces battery power consumption when no load is present. Response from idle is instant. In most cases, the operation of the idle circuit is not noticeable. Using the remote control panel allows the idle circuit sensitivity to be adjusted.

Power Sharing

The Freedom 10 can automatically reduce the battery charger output, and therefore the AC power consumption, if appliances are turned on that threaten to trip the incoming circuit breaker. This feature can be adjusted using the remote control panel. This feature is set to protect a 15-amp source by default.

Installation

Installation Precautions

WARNING: Fire or explosion hazard

This equipment is not ignition protected and employs components that tend to produce arcs or sparks. To reduce the risk of fire or explosions, do not install in compartments containing batteries or flammable materials or areas in which ignition-protected equipment is required.

WARNING: Shock hazard and equipment failure

To reduce the risk of electric shock and prevent premature failure due to corrosion, do not mount where exposed to rain or spray.

WARNING: Fire hazard

To prevent fire, do not obstruct ventilation openings. Do not mount in a zero clearance compartment—overheating may result.

WARNING: Shock hazard

For continued protection against risk of electric shock use only the residual current circuit breaker (RCCB) type receptacles. Other types may fail to operate properly when connected to this inverter, resulting in a potential shock hazard.

WARNING: Shock hazard

Both AC and DC voltage sources are teminated inside this equipment. Each circuit must be individually opened before servicing. When a solar array is exposed to light it supplies DC voltage to the battery and this equipment.

WARNING: Shock hazard

Do not remove cover—no user serviceable parts inside. Refer servicing to qualified service personnel.

Important:

harmonic distortion of 47% and a maximum single harmonic of 34%.

Application Information The Freedom 10 is provided with integral electronic protection against AC and DC overloads.

Appropriate Applications

The Freedom 10 is appropriate for installation in recreational vehicle (RV), residential solar installations, and marine applications. The installation instructions for each application will be discussed separately. Refer to the separate installation guide for typical installation examples.

The output of this device is not sinusoidal. It has a maximum total

2–2 975-0251-01-01

Key Installation Points

• Observe proper polarity when connecting batteries. Reverse DC polarity will result in damage to the Freedom 10.

• Do not backfeed the AC output of the inverter with incoming AC power. Double check all aspects of your AC wiring for the possibility of backfeeding. A backfeed will cause significant damage to your unit.

• Do not connect the AC input to the AC output. In effect, this would be plugging the battery charger into the inverter . This could occur if the Freedom 10 is connected to the entire leg of a circuit breaker panel, then a circuit breaker on that leg is used to feed the battery charger. This will cause the unit to oscillate on and off when the unit is in inverter mode.

• Always use properly sized wire and connectors, keeping in mind that considerable amperage flows in the DC circuit. Fusing the positive DC cable is required.

• Keep the Freedom 10 out of the elements and out of direct contact with water. Remember that the unit is a piece of electronic equipment and treat it accordingly.

• Mount the unit as close to the batteries as possible but not in the presence of flammable fumes or in an enclosed battery compartment.

• Do not bolt the unit down until the AC, remote, and ground wiring is completed.

2. Always mount the unit in a dry area, out of direct contact with water or

spray.

3. You may mount the unit horizontally (on a shelf) or vertically (on a wall or

bulkhead). If mounted vertically, you must orient the unit so the switch and circuit breakers are facing up and the fan and battery cables are facing down.

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 battery terminals. Do not use the RV chassis as a negative conductor.

WARNING: Fire hazar d and equipment damage

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

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

screwdriver to secure it to the chassis ground bonding lug. This wire will connect to the ground in your AC electrical system, typically the vehicle chassis. 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 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 RV is in a campground, the grounding system is connected to the shore power ground, where neutral and earth ground are bonded together. This technique ensures safety in all conditions and conforms to the requirements of numerous electrical codes. Refer to other applicable electrical codes regarding connections between AC ground and DC ground.
