Important Safety Instructions

IMPORTANT: READ AND SAVE THIS INSTALLATION GUIDE FOR FUTURE REFERENCE.
This chapter contains important safety and installation instructions for the Freedom SW Inverter/Charger (Freedom SW). Each time, before using the Freedom SW, READ ALL instructions and cautionary markings on or provided with the inverter/charger, the batteries, and all appropriate sections of this guide. NOTE: The Freedom SW contains no user-serviceable parts. See Warranty and Return Information on the Owners Guide for guidance.
ELECTRICAL SHOCK HAZARD

Do not expose the Freedom SW to rain, snow, spray, or bilge water. This inverter/charger is designed for marine applications only when additional drip protection is installed in certain orientations. See the installation guide for information. Do not operate the inverter/charger if it has received a sharp blow, been dropped, has cracks or openings in the enclosure including if the fuse cover has been lost, damaged, or will not close, or otherwise damaged in any other way. Do not disassemble the inverter/charger. Internal capacitors remain charged after all power is disconnected. Disconnect both AC and DC power from the inverter/charger before attempting any maintenance or cleaning or working on any circuits connected to the inverter/charger. See note below. Do not operate the inverter/charger with damaged or substandard wiring. Make sure that all wiring is in good condition and is not undersized.
Failure to follow these instructions will result in death or serious injury. NOTE: Turning off the inverter/charger using the on/off switch on the front panel will not reduce an electrical shock hazard.
iv
FIRE AND BURN HAZARD

Do not cover or obstruct the air intake vent openings and/or install in a zero-clearance compartment. Do not use transformerless battery chargers in conjunction with the inverter/charger due to overheating.
Failure to follow these instructions will result in death or serious injury.
EXPLOSION HAZARD
Charge only properly rated (such as 12 V) lead-acid (GEL, AGM, Flooded, or lead-calcium) rechargeable batteries because other battery types may explode and burst. Do not work in the vicinity of lead-acid batteries. Batteries generate explosive gases during normal operation. See note #1. Do not install and/or operate in compartments containing flammable materials or in locations that require ignition-protected equipment. See notes #2 and #3.

NOTES: 1. Follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery. Review cautionary markings on these products and on the engine. 2. This inverter/charger contains components which tend to produce arcs or sparks. 3. Locations include any space containing gasoline-powered machinery, fuel tanks, as well as joints, fittings, or other connections between components of the fuel system.
Precautions When Working With Batteries

5. Use extra 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. Batteries can produce a short circuit current high enough to weld a ring or metal bracelet or the like to the battery terminal, causing a severe burn. When removing a battery, always remove the negative terminal from the battery first for systems with grounded negative. If it is grounded positive, remove the positive terminal first. Make sure all loads connected to the battery and all accessories are off so you dont cause an arc.
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND EXPLOSION FROM VENTED GASES HAZARDS
Always wear proper, non-absorbent gloves, complete eye protection, and clothing protection. Avoid touching your eyes and wiping your forehead while working near batteries. See note #4. Remove all personal metal items, like rings, bracelets, and watches when working with batteries. See notes #5 and #6 below. Never smoke or allow a spark or flame near the engine or batteries. Never charge a frozen battery.

7.
Failure to follow these instructions can result in death or serious injury. NOTES: 1. Mount and place the Freedom SW Inverter/Charger unit away from batteries in a well ventilated compartment. 2. Always have someone within range of your voice or close enough to come to your aid when you work near a lead-acid battery. 3. Always have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes. 4. 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.
vi
Precautions When Preparing to Charge
Precautions When Placing the Inverter/Charger
EXPOSURE TO CHEMICALS AND GASES HAZARD

Make sure the area around the battery is well ventilated. Make sure the voltage of the batteries matches the output voltage of the inverter/charger. Be careful to keep corrosion from coming into contact with your eyes and skin when cleaning battery terminals.
RISK OF DAMAGE TO THE INVERTER/CHARGER

Failure to follow these instructions can result in death or serious injury. NOTES: Study and follow all of the battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, whether equalization is acceptable for your battery, and recommended rates of charge. For flooded non-sealed batteries, add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer. This helps to purge excessive gas from cells. Do not overfill. For a battery without removable cell caps, carefully follow manufacturer's instructions.
Failure to follow these instructions can damage the unit and/or damage other equipment.

Planning the Installation

This section provides information to help you plan for a basic installation of the Freedom SW. As your system configuration is determined, record the details in Information About Your System in the Freedom SW Sine Wave Inverter/ Charger Owners Guide.
Two Key Performance Factors

Two key factors in particular will have a major impact on system performance.
Size and Length of DC Cables

To select the appropriate size and length of DC cables, see DC Cabling on page 16. The DC cables should be as short as possible and large enough to handle the required current, in accordance with the electrical codes or regulations applicable to your installation. If there are long battery cables which are in excess of 10 feet each and not of sufficient size, the voltage drop across the cables will have a negative impact on overall system performance.
Mounting Location of the Freedom SW

To choose an appropriate location for mounting the inverter/charger, see Step 1: Choosing a Location for the Inverter/Charger on page 21.
Planning Preparations
AC, DC, and Network Components
Cables, connectors, network connectors, and terminators for the SCP and Automatic Generator Start, if installing. Detailed information on planning and installing your network is available in the Xanbus System Installation Guide. Refer to the system guide to determine the type of network layout to install, as well as guidelines for installing the network. This guide is available for download at www.xantrex.com For a successful installation, you need to plan for AC, DC, and network components of the power system. The AC and DC components are described in this section and illustrated in Figure 3 on page 8.

AC Components
NOTE: Unless otherwise referenced specifically by product name, the components refer to all models of Freedom SW inverter/chargers.
AC Input for Dual AC Line Models

AC inputs (to a dual AC line model such as Freedom SW 3012 inverter/ charger) can be supplied from a split-phase or dual-input AC source such as the utility grid (power company), a generator, or the output of a transfer switch. The Freedom SW can be operated from the following types of 120 volt 60 Hz AC sources: Split phase: This source type has two lines, one neutral, and one ground. The two 120 volts AC lines are 180 degrees out of phase with each other, so that the two voltages total to 240 volts AC line to line. The voltage between each line and neutral is still 120 volts AC, and the voltage between the neutral and ground is approximately zero. Because the two lines are out of phase, the currents from each line subtract in the neutral, and the neutral current will be approximately zero if the loads are equal. For example, if Line 1 is supplying 20 amps and Line 2 is supplying 15 amps, the current in the neutral will be 5 amps. Dual input: This source type has two line inputs, one neutral, and one ground. Unlike the split-phase type, the two lines are in phase (not out of phase), and must come from the same source. The voltage between the two lines is zero. The voltage between each line and the neutral is 120 volts AC, and the voltage between the neutral and ground is approximately zero. Because the two lines are in phase, the currents from each line add together in the neutral. For example, if Line 1 is supplying 20 amps and Line 2 is supplying 15 amps, the current in the neutral will be 35 amps.
AC Input for Single AC Line Models

AC input (to a single AC line model such as Freedom SW 2012 inverter/ charger) can be supplied from a single-phase 120-volt 60-Hz AC source such as the utility grid (power company), a generator, or the output of a transfer switch.
97-0020-01-01

AC Output
The output voltage on Freedom SW inverter/chargers is 120Vac. The AC output line configuration depends on the model. Single AC Line models have a Single Input and Single Output line (SI-SO) configuration. Dual AC Line models support Dual Input and Dual Output lines (DI-DO) configuration.
AC Disconnect and Over-Current Protection Device

To meet CSA, UL, and electrical code requirements, and to protect system wiring, the AC inputs and outputs of the inverter/charger must be provided with overcurrent protection on both the AC input and output. This protection may be a circuit breaker or a fuse with a disconnect device (for simplicity the following refers to breakers). Refer to your applicable installation codes and the following requirements: AC Input Protection The breakers protecting the AC input of the Freedom SW must be approved for use on 120 volts AC branch circuits, and must be located in each Line. The breakers must be rated as shown below: Split-phase input: No more than 30 amps max in each line. Dual input: The neutral current in a dual-input system is the sum of the two line currents, and must be limited to 60 amps maximum to protect the transfer relay in the Freedom SW. Each breaker must not exceed 30 amps, and the total (sum) of the ratings of the two breakers must not exceed 60 amps.
AC Loads
The Freedom SW is intended to power loads consisting of 120 volts AC appliances. In Invert mode, the Freedom SW connects L1 and L2 output lines together to provide 120 volts AC to loads on either line. In AC Bypass mode, the source connected to the AC input is passed through to the load. Because of the way invert mode operates, only 120 volts AC appliances can be connected to the Freedom SW output.
AC Output Protection

Do not connect 240 volts AC loads to the Freedom SW outputs. Doing so may result in 120 volts AC on exposed parts of the appliance. Failure to follow these instructions will result in death or serious injury.
The breaker between the Freedom SW AC output and the AC loads must be rated to protect the AC output wire size used. If the AC output wiring is based on the full 30-amp pass-through rating, then a 30-amp output breaker is acceptable. If the AC output wiring is smaller, then the breaker size will have to be smaller as well, in accordance with applicable electrical installation codes.
12
GFCI Requirements A GFCI (ground fault circuit interrupter) is a device that de energizes a circuit when a current to ground exceeds a specified value that is less than that required to open the circuit breaker. GFCIs are intended to protect people from electric shocks and are usually required in wet or damp locations. Installation in recreational vehicles requires GFCI protection of certain branch circuits. Consult all applicable codes. Tested GFCIs Compliance with UL standards requires that Xantrex test and recommend specific GFCIs for use on the output of the inverter. Table 1 lists models that have been tested and will function properly when connected to the AC output of the Freedom SW. Table 1 Tested GFCI Models
Distribution Panels
Some systems incorporate distribution panels both ahead of the inverter/ charger (the AC source panel) and between the inverter/charger and the loads (the AC load panel). The AC source panel includes a main circuit breaker, which serves as overcurrent protection for the panel. Additional circuit breakers serve individual circuits, one of which serves the inverter/ charger.
AC Wiring
Definition AC wiring includes input wiring (all the wires and connectors between the AC source and the inverter/charger input) and output wiring (all the wires between the inverter/charger and the AC load panels, circuit breakers, and loads). Type The type of wiring required varies according to the electrical codes or regulations applicable to your installation. For RV applications, this may be solid wire in multi-conductor cables, but stranded wire is required if single conductors are used. All wiring must be rated 90 C or higher.

13
Size of AC Input Wiring Wire size must be coordinated with the overcurrent protection provided ahead of the wire involved, in accordance with the electrical codes or regulations applicable to your installation. Therefore, the wiring used between the AC input circuit breaker and the inverter/charger input must be sized to match the input breaker rating. Table 2 AC Wire Size In and Out of the Inverter/Chargers Some conditions for Freedom SW: If the input wiring is split-phase, the output wiring must be sized to coordinate with the breakers used on the input. Refer to your applicable installation codes. If the input wiring is dual-input and the output wiring is single-input, the following rules apply: If the input breaker on L1 is greater than 25 amps, the wire size must be coordinated for that amperage. If the input breaker on L1 is less than 25 amps, the wire size must be coordinated for 25 amps. The wire size must not be sized for anything lower than 25 amps. If both the input and the output wiring are dual-input, the output wiring for each line (L1 and L2) must be calculated separately, following these rules: If the input breaker on the specific line is greater than 25 amps, the wire size for that line and its neutral must be coordinated for that amperage. If the input breaker on the specific line is less than 25 amps, the wire size for that line and its neutral must be coordinated for 25 amps. The wire size must not be sized for anything lower than 25 amps.

AC Output Neutral Bonding

The AC source must have its neutral conductor bonded to ground. Bonding system The Freedom SW provides a system that automatically connects the neutral conductor of the inverters AC output circuit to safety ground (bonding it) while the inverter/charger is inverting, and disconnects it (unbonding it) when the inverter/charger is connected to external AC power. This system is designed to conform to installation codes that require AC sources such as inverters and generators to have their neutral conductors tied to ground at the source of power in the same way that the neutral conductor from the utility is tied to ground. These same codes specify that the neutral can only be connected to ground in one place at any one time. Suitability This automatic neutral-to-ground bonding system requires AC input sources with bonded neutral. This will be the case in most situations: in a utility feed, at an external AC hook-up, or a generator with a bonded neutral. If not, have an electrician look into bonding the sources neutral to ground. See also AC Input and Output Isolation on page 26.

IMPORTANT: Using a smaller gauge cable or a longer cable may cause the inverter to shut down under heavy load.
DC Cabling
Definition DC cabling includes all of the cables and connectors between the batteries, the DC disconnect and overcurrent protection device, and the inverter/charger. Type All installations require multi-strand insulated cables. The DC cables must be copper and must be rated 105 C minimum. Size and Length See Table 3 for required DC cable length, cable size and required fuse size for the Freedom SW. Wire size is usually marked on the cables.
FIRE HAZARD
Battery cables that are very small will melt and burn the first time the inverter is asked to produce high power. Failure to follow these instructions can result in death or serious injury.
16
DC Disconnects and Over-Current Devices

The DC circuit from the battery to the inverter/charger must be equipped with a disconnect and overcurrent protection device. Refer to your applicable installation code for guidance. Type This device usually consists of a circuit breaker, a fuseddisconnect, or a separate fuse and DC disconnect. Do not confuse AC circuit breakers with DC circuit breakers. They are not interchangeable. Rating The rating of the fuse or breaker must be matched to the size of cables used in accordance with the applicable installation codes. Location The breaker or fuse and disconnect should be located as close as possible to the battery in the positive cable. Applicable codes may limit how far the protection can be from the battery.

Installing the Inverter/Charger

Overview
This section provides detailed information on installing the Freedom SW. The overall procedure is divided into eight steps: Step 1: Choosing a Location for the Inverter/Charger on page 21, Step 2: Mounting the Inverter/Charger on page 23, Step 3: Connecting the AC Input and AC Output Wires on page 26, Step 4: Connecting the DC Cables on page 30, Step 5: Connecting the Battery Temperature Sensor (BTS) on page 35, Step 6: Connecting to the Network on page 39, Step 7: Performing Checks Prior to Initial Start-Up on page 40, and Step 8: Testing Your Installation on page 41.
20
Step 1: Choosing a Location for the Inverter/Charger

The inverter should only be installed in a location that meets the following requirements:
This equipment contains components that could produce arcs or sparks. To reduce the risk of fire or explosion, do not install this equipment 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. Failure to follow these instructions will result in death or serious injury. Dry
HEAT HAZARD
Do not cover or obstruct the ventilation openings. Do not install this equipment in a compartment with limited airflow. Overheating may result. Failure to follow these instructions will result in death or serious injury. Cool
Do not allow water or other fluids to drip or splash on the inverter/charger. Do not expose to rain, snow or water. Normal air temperature should be between 32 F and 140 F (0 C and 60 C)the cooler the better within this range. Allow as much space around the inverter/charger as possible. Xantrex recommends that other objects and surfaces be at least 3 inches (76 mm) away from the ventilation openings for best performance.
Clearance

21
FIRE AND EXPLOSION HAZARD
Ventilated
Do not operate the inverter/charger in a closed-in area or restrict ventilation in any way. The inverter/ charger requires air circulation to maintain optimum operating temperature and provide best performance. If the unit has inadequate ventilation, it may shut down due to overheating. The air vented through the openings should also have a path to circulate away from the inverter/ charger.

Safe Locate the inverter/charger away from battery in a separate well ventilated compartment. Do not install the inverter/charger in any compartment containing flammable gases or liquids like gasoline. The length and size of your DC cables will affect performance. Use the DC cables recommended in Table 3 on page 16. The unit should not be installed in the battery compartment due to the possible presence of explosive hydrogen gas from the batteries. Never place the inverter/charger directly above the batteriesgases from battery will corrode and damage the inverter/charger. If the inverter/charger is installed in a compartment above the batteries, make sure there is a solid, gas-impermeable wall dividing the two compartments. Never allow battery acid to drip on the inverter/ charger or its wiring when filling the batteries or reading their specific gravity. To meet regulatory requirements, the Freedom SW must be mounted in one of the approved mounting orientations. See Figure 6 on page 24.

Step 2: Mounting the Inverter/Charger

Considerations
Before mounting the Freedom SW, take the following two factors into account. 1. 2. The weight of the inverter/charger requires two people to install it. Mounting considerations are shown in Figure 6 on page 24. 3. Select an appropriate mounting location and orientation. To meet regulatory requirements, the Freedom SW must be mounted in one of the orientations shown in Figure 6 on page 24. Mark the position of the mounting holes. Pilot drill the six mounting holes. Fasten the inverter/charger to the mounting surface with six 1/4"20 steel screws or bolts.

Step 3: Connecting the AC Input and AC Output Wires

General AC Wiring Considerations
FIRE, ELECTRICAL SHOCK, AND ENERGY HAZARDS
Make sure wiring being connected to the inverter/charger is disconnected (physically or by opening the breaker) from all electrical sources before handling. All wiring must be done in accordance with local and national electrical wiring codes. Failure to follow these instructions will result in death or serious injury. AC and DC Wiring Separation Do not mix AC and DC wiring in the same conduit or panel. Consult the applicable installation code for details about DC wiring and AC wiring in vicinity to each other. AC Input and Output Isolation The AC input and output circuits of this inverter/charger are isolated from each other when in invert mode to ensure safe operation. This isolation must be maintained in the installation, by being sure not to connect AC input and output wiring to a common point. For example, do not route the AC input and output neutrals to a common neutral bus. It is highly recommended to use a separate inverter load panel to distribute power to inverter loads. All wiring to this panel must be through the inverter/charger and none to the main panel upstream of the inverter/charger. IMPORTANT: wiring the output inverter to back to the main panel could result in ground bonding to occur in multiple locations in contravention of applicable wiring codes and may result in nuisance tripping of Ground fault protection equipment. All wiring must be performed by a qualified electrician. AC Wiring Compartment For your reference, the AC wiring compartment is shown in Figure 7 on page 27. AC Knockouts There are two dual 1.0"/ 3/4" trade-size knockouts on the side panel for AC wiring. Use the same trade size of strain relief as the trade size of the knockout(s) you are using. AC Wiring Terminals The AC wiring terminals accept cables of a specific size. See AC Wiring on page 13 for required sizes.

Step 4: Connecting the DC Cables

DC Connection Precautions
2. Cut the DC ground cable to the required length. Strip off enough insulation so you can install the terminals you will be using. Xantrex recommends the use of crimp connectors. The connector should be designed for a 1/4" stud size to connect to the Freedom SW. If a crimp connector is used, it should be crimped using the tool indicated by the connector manufacturer. 3. Attach the connectors to the ends of both cables. Make sure no stray wire strands protrude from the connectors.

Connect and disconnect DC wiring only after opening the disconnect switches or breakers at all AC and DC sources. Failure to follow these instructions will result in death or serious injury.
Recommended Cable Sizes and Lengths and Fuse Size

For recommended DC cables and fuse sizes, see Table 3 and Table 4 on page 17.
Preparing the Cables

To prepare the DC cables: 1. Cut the negative and positive cables to the required length. Strip off enough insulation so you can install the terminals you will be using. Xantrex recommends the use of crimp connectors. The connector should be designed for a 3/8" stud size to connect to the Freedom SW. If a crimp connector is used, it should be crimped using the tool indicated by the connector manufacturer.

Guidelines for Routing the DC Cables

Follow these guidelines to ensure maximum performance.
ELECTRICAL SHOCK AND FIRE HAZARD

Route the cables away from sharp edges that might damage the insulation. Avoid sharp bends in the cable. Failure to follow these instructions will result in death or serious injury. Do not attempt to use the chassis in place of the battery negative connection for grounding. The inverter requires a reliable return path directly to the battery. To reduce the chance of radio frequency interference, keep the positive and negative cables close togetherideally, held together by straps, loom, or insulated clamps at regular intervals. To ensure maximum performance from the inverter/charger, do not route your DC cables through a DC distribution panel, battery isolator, or other device that will cause additional voltage drops. The exception is the DC fuse and Disconnect or the DC circuit breaker which is required at the battery to protect the DC wiring. To help avoid damage caused by reverse polarity battery connection, it is a good idea to mark each end of each cable to identify it as a positive (red) or negative (black) cable before routing the wiring.
97-0020-01-01
31
Connecting the DC Cables to the Inverter/Charger

To connect the DC cables: 1. Route the DC cables from the battery bank to the inverter/charger. Observe the Guidelines for Routing the DC Cables on page 31. Install a DC fuse and disconnect switch or a DC circuit breaker between the inverter/charger and the battery. It must be installed in the positive side of the DC circuit, as close as possible to the battery. This protects your battery and wiring in case of accidental shorting. See Table 4 on page 17 for required fuse or breaker size. 3. 4. Open the DC disconnect switch or turn off the DC circuit breaker. Connect one connector on the POSITIVE (+) cable to the POSITIVE DC terminal on the inverter/charger, as shown in Figure 8. The connector goes on first, then the flat washer (steel), lock washer (steel), and 3/8" bolt (brass). Connect the other connector to the POSITIVE (+) terminal on the fuse or breaker. Observe polarity carefully while completing the installation. Use a wrench to tighten the bolt to a torque of 1516 ft-lbs (20.421.7 Nm) at the inverter/charger end. Observe the fuse holder or breaker manufacturers recommendation at the other end. 6. Connect one connector on the NEGATIVE () cable to the NEGATIVE () DC terminal on the inverter/charger, as shown in Figure 8. The connector goes on first, then the flat washer (steel), lock washer (steel), and 3/8" bolt (brass).
FIRE HAZARD
Use only appropriately sized copper cable. Loose connections, improper connections, and under-rated cables will overheat. Make sure the bolts supplied by Xantrex on the inverter/charger are tightened to a torque of 1516 ft-lbs (20.421.7 Nm). Torque all other connections to the manufacturers specifications. Make sure the DC cable, washers, and bolt are assembled in the order shown in Figure 8. Failure to follow these instructions will result in death or serious injury.
2.
EQUIPMENT DAMAGE DUE TO REVERSE POLARITY

Before making the final DC connection or closing the DC breaker or disconnect, check cable polarity at both the battery and the inverter/ charger. Positive (+) must be connected to positive (+). Negative () must be connected to negative (). Failure to follow these instructions can damage the unit and/or damage other equipment.
5.
32
Figure 9 DC Terminal Covers Figure 8 DC Cable Connections 7. Before proceeding, check that the cable polarity is correct: POSITIVE (+) on the inverter/charger is connected to the POSITIVE (+) on the battery, and NEGATIVE () cable is connected to the NEGATIVE () terminal on the inverter/charger.
IMPORTANT: The next step is the last cable connection you need to make. A spark is normal when the DC disconnect switch is turned on or the DC circuit breaker is closed so be sure step #3 is done before proceeding. 8. 9. Connect the other end of the cable to the NEGATIVE () terminal on the battery. Use a wrench to tighten the bolt to a torque of 1516 ft-lbs (20.421.7 Nm) at the inverter/charger end.

DC Grounding
The Chassis Ground point on the inverter/charger is used to connect the chassis of the inverter/charger to your systems DC grounding point, as required by regulations for some installations. Use copper wire that is either bare or provided with green insulation. The grounding guideline given below assumes you are using the codecompliant DC supply cable and fuse sizes indicated on page 16. If you are using different sizes, refer to the applicable code for DC grounding detail. To connect the chassis ground: 1. 2. Using the appropriate wrench, loosen the bolt on the chassis ground point shown in Figure 10. Connect the grounding cable between the chassis ground point and the DC grounding point for your system. In an RV or vehicle installation, the DC grounding point will usually be the vehicle chassis or a dedicated chassis ground bus. 3. Tighten the screw to a torque of 1.01.25 ft-lbs (1.471.7 Nm).

Step 5: Connecting the Battery Temperature Sensor (BTS)

Installing a battery temperature sensor (BTS) extends the life of a battery by preventing overcharging in warm temperatures and undercharging in cold temperatures. With a BTS monitoring the battery temperature, the voltage delivered to the battery is adjusted according to the batterys actual temperature. The BTS has a self-adhesive backing and attaches to the side of the battery. A 25-foot (7.6 m) cable is supplied with the BTS. Sensor cable
Connector
Mounting Options
You can mount the BTS in one of two ways: Mounting the sensor to the negative battery post allows the internal battery temperature to be sensed and provides the most accurate results. Attaching the sensor to the side of the battery using the self-adhesive backing also provides good results in most situations. Sensor

Mounting to the Negative Battery Terminal

To mount the sensor on the negative battery terminal:
3. 4. 5.
Wait 10 minutes for any explosive battery gases to dissipate. Remove the nut that connects existing wiring ring terminals to the battery negative terminal stud. Move or reorient the existing wiring ring terminals on the battery negative terminal stud, so there is a flat surface on which to seat the BTS mounting plate. You may need to bend the ring terminal crimp and/or wires slightly downward to allow the sensor to seat flush to the top surface of the upper ring terminal.
Negative () battery terminal 6.
Mount the sensor directly on top of the ring terminal, as shown in Figure 12, and firmly tighten the terminal nut.
FIRE HAZARD
In this procedure, you must install the DC wire on the battery terminal, then install the sensor on top of the DC wire. This sequence is required to provide the best connection to the battery and to ensure correct performance of the sensor. Failure to follow these instructions will result in death or serious injury. Figure 12 BTS Mounted on the Negative Battery Terminal 1. 2. Select the battery to be monitored. The BTS should be connected to the battery bank that is directly connected to the inverter/charger. Switch off all devices operating from the battery, or open the battery switch (if present) to disconnect the battery. 7. 8. Check to ensure that the sensor and all wires are held firmly and cannot be moved. Turn the battery switch on again (if you opened it in Step 2.)

Testing in Invert Mode

To test the Freedom SW in invert mode, using a 100 watt light bulb as the test load: 1. Close the DC disconnect switch or the DC circuit breaker to supply DC power to the Freedom SW. Wait for all the lights on the front panel to flash on and off, indicating that the unit has successfully initialized (10 to 30 seconds). If the light does not come on, make sure the voltage at the DC terminals on the Freedom SW is correct, as described in Step 7: Performing Checks Prior to Initial Start-Up on page 40.
If the test fails at any point, go to Step 7: Performing Checks Prior to Initial Start-Up on page 40 and go through the checklist again to check the installation. Then perform the test again. If the test fails again, see the troubleshooting section in the Freedom SW Sine Wave Inverter/Charger Owners Guide.

2. 3. After initialization, observe that none of the lights on the front panel should remain illuminated. Press the Inverter Enable button. Verify that: 4. The Inverter Enable button light illuminates, The Invert On light illuminates. To verify that the Freedom SW starts charging: 2. After a few seconds, verify that the AC/Charge light on the front panel is turned on (indicating that the batteries are being charged).
Testing in Charge Mode and AC Bypass Mode

1. Close the AC supply breaker to supply AC power to the unit.
Connect the Freedom SW to the test load by closing the AC breaker that controls the circuit that the test load is connected to. If the light bulb illuminates, the Invert mode is working. Press the Inverter Enable button to disable the inverter. The Invert On light and Inverter Enable button light are off. 4. 5. 3.
To verify that Freedom SW correctly switches to Bypass mode: Disable the AC source and turn off the inverter by pressing the Inverter Enable button. Connect the test load to the AC output connection of the unit. Enable the AC source and the test load should turn on after ten seconds.
5.
Installation Complete
Your installation is now complete. The inverter/charger is ready for use. The preceding tests use a light test load (a light bulb) as a test case. If you encounter problems when using a load over 1000 watts (for example, a hair dryer or microwave), see the troubleshooting information in the Freedom SW Sine Wave Inverter/Charger Owners Guide.

Stacking Features
43
The Freedom SW inverter/chargers provide supports two stacking configurations. This gives the system engineer and/or installer more options to work with when tailoring a system to meet load demands. Multiple inverter/chargers of different power levels can be installed in a system as stand alone, parallel stacked, or series stacked. In parallel stacking mode, only two Freedom SW inverter/chargers of the same model can be parallel-stacked. For example, two Freedom SW 2012s can be stacked in parallel as both units each have a 12-volt rating and a power rating of up to 2000 watts. For now, a Freedom SW 2012 which is 12-volt rated cannot be parallel-stacked with a Freedom SW 2024 which is 24-volt rated. See parallel stacking section. In series stacking mode, you may stack two different Freedom SW inverter/ chargers of different power ratings but same voltage ratings. For example, a Freedom SW 2012 can be series-stacked with a Freedom SW 3012. However, a Freedom SW 2012 which is 12-volt rated cannot be seriesstacked with a Freedom SW 2024 which is 24-volt rated. See series stacking section.
DAMAGE TO INVERTER/CHARGER
When stacking two Dual Input Line/Dual Output Line (DI-DO) models such as two Freedom SW 3012 units, do not connect any wires to the AC INPUT L2 terminals on both units at all. The same applies to the AC OUTPUT L2 terminals on both units. Any damage sustained by noncompliance may result in non warrantable damage to the inverter/ chargers. The only exception is AC OUTPUT N2. See parallel stacking section. Failure to follow these instructions can damage the unit and/or damage other equipment.
97-0020-01-01
Stacking Features
Parallel Stacking
Allows the inverter and charger capacity of a system to be doubled. Parallel-stacked inverter/chargers can operate from different battery banks, meaning each unit is connected to its own battery bank. However, it is highly recommended to only use a single battery bank. See DC Connections for Stacked Inverters on page 47. AC INPUT L2 terminals on both units must not be connected at all as they are not monitored lines. IMPORTANT: Freedom SW models with dual AC lines do not monitor voltage and current on AC INPUT L2 and AC OUTPUT L2. If any L2 line is connected, any current flowing in this branch will not be displayed. AC OUTPUT L1 and AC OUTPUT L2 must not be connected together. However, the two output neutrals (AC OUTPUT N1 and AC OUTPUT N2) can be tied together for redundancy. This reduces stress on the neutral path internal to the unit since two circuits will carry the load current.

Freedom SW models with the same DC voltage rating can also be assembled in a system. For example, a Freedom SW 3012 can be installed on L1 while a Freedom SW 2012 operates on L2. However, it is important to remember that for Freedom SW inverter/chargers that support dual line AC configuration (DIDO), only AC INPUT L1 terminal should be used and that the AC INPUT L2 terminal must have no connections at all. If L2 is connected to any incoming or outgoing AC line, the inverter/charger may suffer internal damage not covered by warranty.

Stacking Cable
For series stacking (120 and 240 volts), connect the Xantrex stacking cable between the two STACKING ports.
Theory of Series Stacking Operation

The inverter is designed to accept power input from a single-phase, threewire 120/240-volt AC system with 120 volts to each inverter. The input line (INPUT L or L1) terminal of each inverter accepts one leg of 120 volts each and the input neutral (INPUT N) terminals of both inverters are tied together and connected to the power source neutral leg. Any AC loads being powered while AC input is present to the inverters will be in addition to the power being drawn for charging the batteries. Each unit in the stack can provide a full pass-through current of 50 amps for 120-volt systems. When AC input power is lost, both units in the stack switch from charger to inverter mode. Once this switch is made, 120 volts AC is available from each individual inverter or 240 volts AC is available across the output line (OUTPUT L or L1) terminals of the stacked pair. Stacked inverters will typically support about twice the surge power of one standalone unit. For example, a Freedom SW 3012 stacked pair will surge about 12000 watts.

Neutral Wiring for Stacked Inverters

Due to the neutral ground switching design of the Freedom SW Inverter/ charger, it is mandatory that the AC INPUT and AC OUTPUT Neutrals be isolated from one another. In a stacked pair configuration, connect the two AC input neutrals together at the main distribution panel and the two AC output neutrals at an isolated neutral location in the inverter AC distribution panel.
Configuring System for Stacked Operation

Verify all DC and AC connections. Check Xanbus network connections and ensure that terminators are installed at devices at each end of the network. The simplest system includes a Xanbus SCP, the two Freedom SW inverter/ chargers to be stacked and two Xanbus terminators. For both units to operate in stacked configurations, a Master and Slave have to be assigned. The default out-of-box configuration for all Freedom SW inverter/chargers is Master which causes a conflict the first time the system is powered up. The installer will need to change configuration on one of the inverter/chargers to Slave mode. To configure the system for stacking:

Stacking Features
Search Mode Operation in Parallel Stacking

When two inverter/chargers are stacked for parallel operation, search mode behavior on the Slave unit is modified and is dependent on how much total load is on the system.
Disabling Search Mode on the Master Unit

In parallel stacking, search mode on the Master unit will not function properly. When the Master sends out a load search pulse, a small current also flows into the output of the Slave unit since the two outputs are in parallel. This Master unit falsely detects a load causing erratic search mode operation. For this reason, it is highly recommended to disable search mode on the Master unit in a parallel stacking system.
Setting Search Mode on the Slave Unit

The Slave unit will behave in one of two ways depending on whether its search mode is enabled or disabled. Search mode enabled This is the recommended mode for parallel stacking and it helps minimize battery draw. The Slave unit continuously monitors the output of the Master unit. If the Master unit has more than 60% of the rated load (e.g., 1800 watts on Freedom SW 3012), the Slave unit will assist the Master and the two will share the load equally. Should the load on the Master drop below 20% of rated load (600 watts for Freedom SW 3012), the Slave unit disengages and returns to a waiting state. Search mode disabled The Slave unit operates continuously along with the Master unit and shares the load.

Battery Information
Battery Bank Sizing
Battery capacity Battery size or capacity is just as important as the battery type selected for use with the Freedom SW. The batteries are the most important part of your system, so Xantrex recommends that you purchase as much battery capacity as possible. A large battery will extend running time and ensure that your inverter/charger delivers full rated surge. Xantrex recommends a minimum battery size of 200 amp-hours (Ah) for moderate loads (<1000W) and greater than 400 Ah for heavy loads. See Estimating Battery Requirements for information on a more detailed calculation. About Amp-hours A number of different standards are used to rate battery energy storage capacity. Automotive and marine starting batteries are normally rated in cranking amps. This is not a relevant rating for continuous loads like an inverter. Deep-cycle batteries use a more suitable rating system such as amp-hours (Ah). Amp-hour capacity is the number of amps a battery can continuously deliver during a specified number of hours. It is represented by the product of the two amps multiplied by hours. A typical marine or RV battery rated for 100 Ah can deliver 5 amps for 20 hours (5 amps 20 hours = 100 Ah). This same battery can deliver a higher or lower current for less or more time, limited approximately by the 100 Ah figure (50 amps for 2 hours or 200 amps for 1/2 hour), but usually the capacity figure given is only accurate for the specified duration (20 hours). 2.
Estimating Battery Requirements

Calculating Battery Size
Step 1: Compute Amp-hours For each appliance, compute the number of amp-hours that will be used between charging cycles, as follows: 1. Obtain the wattage. If the wattage is marked on the nameplate rating, use that. Otherwise, multiply the marked voltage and amperage: WATTS = VOLTS AMPS. Obtain the Watt-hours by multiplying that amount by the hours the appliance will be used: WATT-HOURS = WATTS HOURS. Obtain the amp-hours that the appliance requires by dividing that amount by 10 (the factor for the Freedom SW, which is a 12-volt system): BATTERY AMP-HOURS USED = AC WATT-HOURS/10
3.
For example, a 100 W light bulb that is used for 4 hours will use 400 watthours (Wh) and the inverter will consume approximately 40 Ah from a 12 volt battery. 4. 5. Enter this information on the blank calculation worksheet (page 56). Complete the rest of the worksheet; see Table 6, Battery Sizing Example on page 54 for an example. Step 2: Calculate Battery Size
97-0020-01-01
53
Battery Information
Size the batteries at approximately twice the estimated total amp-hour usage. Doubling the expected amp-hour usage ensures that the batteries will not be overly discharged and extends battery life. Do not skip this doubling step. More capacity is better since you will have more reserve capacity, be better able to handle large loads and surge loads, and your battery wont be discharged as deeply. Battery life is directly dependent on how deeply the battery is discharged. The deeper the discharge, the shorter the battery life. Table 6 Battery Sizing Example Troubleshooting If you find that the system shuts down when appliances with large motors are started, the problem may be that this motor is too much for the battery. Even though you calculated the amp-hour requirements appropriately, the startup of a large motor makes high demands on the battery. You may find that adding more amp-hours (in the form of extra batteries or replacement with a bigger battery) solves the problem.

This example illustrates how quickly your battery needs can escalate. To reduce the required battery bank size, you can either conserve energy by eliminating or reducing the use of some loads, or recharge more frequently.

Battery Information
Battery Banks
As your power requirements increase, you may need to use more than one battery to obtain sufficient capacity. Batteries can be connected in parallel, in series, or in series-parallel to create higher capacity systems. See Battery Cabling and Hook-up Configurations on page 57 for more information about battery inter-connection schemes. Mixing Batteries Batteries connected in parallel should be of the same type and amp-hour rating and from the same manufacturer. It is not recommended to connect batteries of different types, amp-hour ratings or manufacturers. Improper charging and decreased battery life will result.
Restrictions on Motor Size

An appliance may require three to six times its normal running current in order to start. The Freedom SW can handle surges to 6000 watts for five seconds, which translates to a locked-rotor-amp rating of no more than 50 amps. The locked rotor amp may be specified on the motor nameplate as LRA or LRI. When considering appliances with large motors, follow these guidelines: Make sure that the motors LRA rating is no more than 50 amps. The Freedom SW may not be able to start a motor with a higher LRA, and the Freedom SW will shut down if the attempt is made. Make sure the battery bank, DC cables and DC fuses are capable of handling up to 600 amps DC for five seconds. A weaker circuit may not be able to provide sufficient power to the Freedom SW to allow the Freedom SW to start up the appliance. Again, if the circuit cannot deliver the required current, the system may shut down or the fuse may open.

Battery Cabling and Hook-up Configurations

Several smaller batteries can be connected to create a battery bank of substantial size. You can connect batteries in three ways: in parallel, series, or series-parallel. To make a larger battery bank, connect individual batteries with heavy cables. The actual size of the cable depends on whether the batteries are connected in parallel or series. Generally, the cable should not be smaller than the inverter cablesif the main cables are 4/0 AWG, the battery interconnects should be 4/0 AWG. The best configuration is to connect the batteries in series and parallel. This requires additional cables, but reduces imbalances in the battery bank and can improve the overall performance. Consult your battery supplier for more information regarding the hook-up configuration required for your system.
Battery Parallel Connection

Batteries are connected in parallel when all the positive terminals of a group of batteries are connected and then, separately, all the negative terminals are connected. In a parallel configuration, the battery bank has the same voltage as a single battery, but an Ah rating equal to the sum of the individual batteries. See below.

Battery Cabling and Hook-up Configurations
Battery Series Connection

When batteries are connected with the positive terminal of one battery to the negative terminal of the next battery, they are connected in series. In a series configuration, the battery bank has the same Ah rating of a single battery, but an overall voltage equal to the sum of the individual batteries. See below.
Battery Series-Parallel Connections

As the name series-parallel implies, both the series and parallel configurations are used in combination. The result is an increase in both the voltage and the capacity of the total battery bank. This is common with all battery-inverter system voltages. The smaller, lower voltage batteries are first connected in series to obtain the necessary voltage, and then these batteries connected in series sets are connected in parallel to increase the battery bank capacity. See below.
