Important Safety Instructions
IMPORTANT: READ AND SAVE THIS OWNER’S 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.
NOTE: Turning off the inverter/charger using the on/off switch on the front
panel will not reduce an electrical shock hazard.
ELECTRICAL SHOCK HAZARD

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.

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.
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.
• Do not work in the vicinity of lead-acid batteries. Batteries generate
explosive gases during normal operation. See note #1.

Precautions When Working With Batteries
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.
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.
6. 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.
7. 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 don’t 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.
Failure to follow these instructions can result in death or serious
injury.

Precautions When Preparing to Charge
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.

Introduction
Key Features
The Freedom SW Inverter/Charger is a true sine wave inverter/charger that
can be used for mobile, marine and commercial applications. The Freedom
SW Inverter/Chargers are designed to operate with a wide variety of
generators and are capable of operating in parallel with a generator for short
durations to assist with starting large loads. The Freedom SW is a
convenient combination of an inverter, multistage battery charger, and
transfer switch in one electronic device.
• As an inverter, the Freedom SW provides true sine wave power for
your microwave, entertainment system, computer, and other loads.
This power is identical to the AC source provided from the utility grid
(power company).
• Some of the benefits of true sine wave power include consistent
cooking in your microwave, handling of sensitive loads such as your
TV set, dimmer switches, and appliances with speed controls.
• Highly versatile platform capable of series stacking for 120/240V line
configurations and parallel stacking to increase power levels.
• High efficiency true sine wave output to power sensitive electrical and
electronic equipment.
• Surge capacity to start difficult loads like well pumps, refrigerators, or
A/C compressors.
• Power factor-corrected (PFC) input minimizes AC input current
required for charging, increasing AC pass-through capacity.
• As a charger, it has high output, multi-stage charging capability
minimizing charging time.
• Capable of operating from 50Hz and 60Hz power source by extending
AC qualification frequency range. See “ACIn Settings” on page 52.
IMPORTANT: Dual Line models require only the Line 1 Input to be
energized in order to qualify AC. Line 2 Input does not have to be
powered in a single phase system.
• Temperature-controlled, variable-speed internal cooling fans. The fans
turn on when the internal temperature reaches 45 °C (113 °F) and
reaches maximum speed at 70 °C (158 °F). The fan turns off when the
internal temperature falls to 40 °C (104 °F).
• Designed with efficient field serviceability in mind.
• The Freedom SW Inverter/Charger is also Xanbus-enabled which
allows network compatibility and communication with other Xanbusenabled devices. See more information under “System Components”
on page 6.
Key Features Explained
Built-in Charge Formulas For the unit to perform at the highest level,
the batteries must be charged correctly. The Freedom SW has optimized
algorithms for flooded, gel, and AGM batteries.
Battery Temperature Sensor Since battery temperature is a key factor in
correct charging, the charging formula must be adjusted (automatically and
in real time) according to the actual battery temperature to ensure that
batteries are fully charged, but not overcharged. For this reason, a battery
temperature sensor is included with your Freedom SW and has temperature
compensated the charge formula.
Freedom SW 3K2K InvChg Owners Guide.book Page 2 Wednesday, October 9, 2013 1:34 PM

Introduction
Manual Equalization Over a period of time, the cells in a flooded
battery can develop uneven chemical states. This can result in a weak
(undercharged) cell which, in turn, can reduce the overall capacity of the
battery. To improve the life and performance of a non-sealed, flooded
battery, the Freedom SW’s multi-stage charging cycle includes a manual
equalize mode that can be used, if recommended by the battery
manufacturer.
Dead Battery Charging Another feature that the Freedom SW includes
is dead battery charging. The Freedom SW—unlike many chargers—has
the ability to recharge batteries even if the battery voltage is very low, i.e.,
as low as 3 volts.
Load Management The Freedom SW has a built-in transfer relay that
connects your inverter output or AC input from the utility grid or generator
to your loads. Because the usual AC power sources such as campground
outlets or small generators often have limited current availability, having
the capability to manage your AC loads is extremely valuable. The
Freedom SW provides a number of features to facilitate this:
• The charger is power factor corrected to use AC current as efficiently
as possible. Minimizing the AC current used by the charger means
more current is available for your AC loads.
• Freedom SW has a power share feature which prioritizes your AC
loads by reducing the charge current and maintaining the total input
current to less than the breaker setting.
Occasionally, AC input sources have low voltage. To avoid loading these
weak sources any further, the charger automatically reduces its AC current
draw as the AC voltage approaches the minimum acceptable level.
Stacking
Supports stacking of two inverter/chargers to increase capacity. This also
requires the installer to select a Master and Slave in order for the inverters
to stack. Two configurations of stacking are supported: Parallel stacking
and Series stacking.
Parallel Stacking
Parallel stacking allows two inverter/chargers to operate in parallel thereby
doubling the capacity in inverter mode. The two inverters communicate
over the network and intelligently share the load and to balance the load
between the two units. The Master Freedom SW broadcasts pulses on the
Xanbus network to synchronize operation between the other paralleled unit.
When AC loads are present, both units produce power, effectively sharing
the load. When Search mode is enabled, only the Master unit produces the
AC output.
Series Stacking
Two units can be configured to generate 120/240 Split-phase power for load
configurations that require both 120 and 240 volts. In this configuration, the
AC source must be split-phase as well.
Freedom SW 3K2K InvChg Owners Guide.book Page 3 Wednesday, October 9, 2013 1:34 PM
4 Freedom SW Owner’s Guide
Introduction
Stack Charging
Multiple Freedom SWs synchronize charging stages to ensure efficient
charging of the battery bank. When a single unit transitions from bulk to
absorption so do all other units. In absorption, all units must complete the
absorption stage before transitioning to the next stage. Note that units do
not load share when charging except during the bulk stage. The Freedom
SWs stop sharing charge current just before completing the bulk stage. The
units do not share charge current during the absorption and float stages.
Each unit charges batteries based on the Max Charge Rate setting and active
internal (temperature-based) deratings.
If equalization is enabled on one or more devices capable of equalization
charging, only those devices perform an equalize cycle after absorption.
Other devices transition to float (if three-stage charging is selected) or
transition to AC pass-through (if two-stage charging is selected).
Generator Assist
The Freedom SW Series of inverter/chargers can operate in tandem with a
generator to temporarily assist power loads with large start-up demands
such as air conditioners, water pumps etc. A Xanbus AGS must be installed
in the system in order for this feature work.
When this mode is enabled and generator capacity defined, the inverter will
come on-line and assist the generator when the generator reaches its
capacity. The battery bank must be well charged in order for the inverter to
engage this mode. For more details, see “Gen Support” on page 53.

Introduction
Basic Protection Features
The Freedom SW has the following protection features:
• over temperature shutdown for critical components such as the
transformer and the power board
• battery temperature sensor (BTS) failure/battery temperature out-ofrange fault protection
• DC output over voltage protection during charge mode,
• AC transfer relay failure detection
• AC output overload and short circuit protection during invert mode
• AC backfeed

protection
• short circuit protection for the BTS and communication connector
ports including protection from incorrectly inserting the remote panel
communication cable plug into the BTS port and vice versa
The Battery Temperature Sensor (BTS) provides these protection features:
• battery over temperature charging protection preventing battery
charging at 60 °C (140 °F) or higher
• charging voltage compensation based on the temperature of the battery
the BTS is connected to
1.An AC backfeed error occurs when the AC output of the inverter/charger is connected or routed back to the inverter/char ger’s AC input terminal or if the internal
transfer relay fails.

System Components
The Freedom SW uses Xanbus, a network communications protocol
developed to communicate the Freedom SW’s settings and activity to other
Xanbus-enabled devices.
You can configure and monitor the Freedom SW and every Xanbus-enabled
device in the system using an optional Xanbus System Control Panel (SCP).
Another component is the optional Xanbus Automatic Generator Start
(AGS) which allows operation with a wide range of generators, supported
through a dedicated generator input. Simply, the AGS automatically starts
and stops your generator.
The Freedom Sequence Intelligent Power Manager is a fully integrated
power management system that provides automatic power and load
management for use in recreational vehicles (RV) while receiving power
from a generator or shore power. This device works in the background to
prevent monitored AC loads from exceeding shore and generator breaker
capacity.
See “Xanbus-enabled Products and Accessories” on page 7 for part
numbers.
Xanbus System
The Xanbus system includes the Freedom SW and other Xanbus-enabled
devices. The Freedom SW is the device in a Xanbus system that typically
provides network power—500 mA at 12 volts DC. All of the Xanbusenabled devices, such as the Freedom SW, the SCP, and the AGS are able to
communicate their settings and activity to each other. See Figure 1.

Freedom Inverter/Charger Operation
Start Up Behavior
When the Freedom SW is powered up or has been reset, all of the front
panel lights illuminate and remain on for a minimum of five seconds.
During this interval, the fans are also turned on as the unit executes internal
diagnostics.
The Freedom SW inverter is disabled every time the Freedom SW is
powered up. After power up, the INVERTER ENABLE button (or the SCP)
can be used to enable or disable the inverter.
When a function is enabled, it is allowed to occur but other conditions may
have to be met before the function is activated or turned on. For example,
the charger function on the Freedom SW may be enabled, but it will not
charge unless qualified AC power is present.
IMPORTANT:
Review the “Important Safety Instructions” on page iv
before operating the inverter/charger.

Freedom Inverter/Charger Operation
Inverter Operation Using the Front Panel
Once the inverter/charger is installed, you can operate it in invert mode.
To operate in invert mode from the front panel:
1. Press the INVERTER ENABLE button on the Freedom SW on the front
panel. The INVERTER ENABLED LED illuminates and connected loads
will be energized.
2. Note that if AC is present and being passed through, the INVERTER
ENABLED LED will still illuminate to indicate inverter mode has been
enabled. However, AC will continue to be passed through to the loads
until conditions exist that cause AC to be disqualified, in which case
the unit will transition to invert mode and power up critical loads.
3. Connect AC input power.
The charger automatically starts up when qualified AC power is
connected.
To operate the inverter with the System Control Panel, refer to
“Operating the Freedom SW with the SCP” on page 15.
4. Disconnect AC power from inverter input by opening the breaker or
disconnect.
5. Place a load on the inverter. For example, plug a 100-watt light bulb
into an outlet that the inverter is powering. Press the INVERTER
ENABLE button on the Freedom SW. The INVERTER ENABLED LED
illuminates. The inverter should run the load using battery power.
6. To test the charger, reconnect the AC input power to allow AC to the
AC input. The AC/Charger On LED should start flashing after a brief
delay. Any AC loads previously powered by the inverter will also
work at this time.
NOTE: On dual input models, only AC Input L1 needs to be powered
for the unit to operate.
7. Remove the AC input power. The inverter/charger should transfer to
invert mode immediately. (T he tr ansfer relay will make a clicking
sound and the INVERTER ENABLED LED will illuminate.) Loads
should continue to operate uninterrupted.
If any part of this test fails, determine the cause before using the unit.
8. Monitor the Freedom SW Front Panel.
The indicator lights on the front panel show you the operating status of
the Freedom SW. A description of the lights is provided in Table 1.
If none of the front panel lights are on, see “Troubleshooting” on page
65.
IMPORTANT:
Review the “Important Safety Instructions” on page iv
before operating the inverter/charger.

Freedom Inverter/Charger Operation
Faults and Warnings A fault affects the operation of the unit. A manual
fault requires user intervention by clearing the condition and then pressing
the CLEAR FAULT RESET button on the inverter/charger’s front panel. See the
Xanbus System Control Panel Owner’s Guide for information on clearing
faults from the SCP.
A warning alerts you to a condition that could possibly affect operation of
the unit.
Operating Limits for Inverter Operation
Temperature The Freedom SW series of inverter/chargers will operate at
rated power continuously at 30 °C with some models capable of continuous
operation at much higher ambient temperature. However, the continuous
power rating at elevated ambient temperature may differ between models.
See “Specifications” on page 77 for full details. In higher ambient
temperatures, if the loads draw full power for an extended period of time,
the unit may shut down to protect itself against overheating.
The Freedom SW series of inverter chargers feature a surge rating of 200%
of rated power for five seconds at 25 °C. Operating the inverter/charger in
conditions outside of power and temperature limits, however, will result in
thermal shutdown and/or significantly decreased performance. In addition,
operation in this range is outside the ratings covered by the regulatory
approvals of the product.
Difficulty on starting loads The inverter/charger should be able to
operate all AC loads rated at or below its power rating. Some high
horsepower induction motors used in pumps and other motor-operated
equipment require very high surge currents to start, and the inverter/charger
may have difficulty starting these loads.
If you have problems starting certain loads, ensure that:
• the battery connections are tight and clean.
• the DC cabling is no longer than the recommended length. Refer to the
Freedom SW Sine Wave Inverter/Chargers Installation Guide for this
information.
• the AC wiring is of recommended size. Refer to the Freedom SW Sine
Wave Inverter/Chargers Installation Guide for this information.
• the battery is of sufficient capacity and is fully charged.

Freedom Inverter/Charger Operation
Operating Limits for Charger Operation
By default, the maximum charger output current is the rated charger output
current for the particular model. Using the SCP, you can reduce the total
output if you change the maximum charge rate (Max Chg Rate) on the
Freedom SW Basic Settings menu or Inverter Settings menu under
Advanced Settings.
The charger can operate over an AC input range of 95–135 volts AC. This
is the default setting and can be adjusted to 78–145 volts AC as a maximum
range and to 110–120 volts AC as a minimum range. The charger can also
be configured to accept and operate from a wide AC source frequency of 40
to 70 Hz. The default setting is 55 to 65 Hz. This wide range allows the
Freedom SW to charge your batteries even when incoming AC voltage is
less than ideal or a 50 Hz source.
Power Share The Freedom SW charger uses AC input line 1 to charge
the batteries. The Freedom SW charger shares incoming power with AC
loads on line 1 only. The AC loads have priority, which means that the
charger will reduce its output with large AC loads and increase the output
again when the AC load decreases. The regulatory maximum for
continuous AC loads is 80% of the breaker rating that the loads are
connected to.
The Freedom SW senses pass-through current going to the AC load. The
difference between the pass-through (load) and 80% of the Power Share
setting is the current that is available for charging the batteries.
For example, if the AC input of the Freedom SW is from an AC panel with
a 30-amp breaker, the Power Share setting on the SCP should be selected as
30-amp. Based on this, the charger will control the charge current so that
the total current draw is equal to or less than 24 amps in this case. Should
the load current be more than about 24 amps, the charger output will reduce
to 0 amp, but the Freedom SW will continue to supply the loads. The
Freedom SW will continue to pass-through power to the loads, even if the
load current exceeds the Power Share setting. In this case, it will be up to
the user to remove/disconnect loads if tripping the AC input breaker
supplying the Freedom SW is to be avoided.

Operating the Freedom SW with the SCP
This section contains detailed information and procedures for using your
Freedom SW in conjunction with the SCP.
If you’re using the SCP to operate or monitor the status of the unit, you may
also refer to the Xanbus System Control Panel Owner’s Guide.
The SCP provides operating, configuration, and monitoring capability for
your Xanbus system.
The System Control Panel:
• Monitors activity throughout your onboard power system.
• Displays the latest information about your inverter/charger, battery
voltage level, battery charge output, and generator start and stop
activity.
• Displays the settings for each Xanbus-enabled device in the system.
• Enables you to adjust the settings for each Xanbus-enabled device in
the system.
• Preserves all of its settings if system power is interrupted. After power
is restored, you don’t have to reconfigure the SCP or any of the
Xanbus-enabled devices connected to it.
This section provides information on operating the Freedom SW with the
System Control Panel. Please refer to the System Control Panel Owner’s
Guide for complete information on using the System Control Panel.
LIMITATIONS ON USE
• Do not use in connection with life support systems or other medical
equipment or devices.
• Do not use in ambulances or other life-saving emergency vehicles.
Failure to follow these instructions can result in death or serious
injury.
