This guide for use by qualified installers only  
   
6. Do not disassemble the Freedom HW. It contains no user-serviceable  
parts. See Warranty for instructions on obtaining service. Attempting  
to service the Freedom HW yourself may result in a risk of electrical  
shock or fire and will void your warranty. Internal capacitors remain  
charged after all power is disconnected.  
7. To reduce the risk of electrical shock, disconnect both AC and DC  
power from the Freedom HW before attempting any maintenance or  
cleaning or working on any circuits connected to the Freedom HW.  
Turning off controls will not reduce this risk.  
8. The Freedom HW must be provided with an equipment-grounding  
conductor connected to the AC input ground.  
WARNING: Explosion hazard  
1. Working in the vicinity of batteries is dangerous. Batteries generate  
explosive gases during normal operation. Therefore, it is of utmost  
importance that each time before servicing the unit in the vicinity of  
the battery, that you read this manual and follow the instructions  
exactly.  
2. This equipment contains components which tend to produce arcs or  
sparks. To prevent fire or explosion, do not install the Freedom HW  
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  
system.  
3. To reduce the risk of battery explosion, follow these instructions and  
those published by the battery manufacturer and the manufacturer of  
any unit you intend to use in the vicinity of the battery.

Personal Precautions When Working With Batteries  
WARNING: BATTERIES PRESENT RISK OF ELECTRICAL SHOCK  
,
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE OR  
EXPLOSION FROM  
PRECAUTIONS  
VENTED GASES. OBSERVE PROPER  
.
1. Study and follow all of the battery manufacturer's specific  
precautions, such as removing or not removing cell caps while  
charging, and recommended rates of charge.  
2. 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 cell caps,  
carefully follow manufacturer's recharging instructions.  
3. Make sure the area around the battery is well ventilated.  
4. Never smoke or allow a spark or flame near the engine or 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.  
6. Remove all metal items, like rings, bracelets, and watches when  
working with batteries. Batteries can produce a short circuit current  
high enough to weld metal to skin, causing a severe burn.  
7. Have someone within range of your voice or close enough to come to  
your aid when you work near a lead-acid battery.  
8. Have plenty of fresh water and soap nearby in case battery acid  
contacts skin, clothing, or eyes.  
9. Wear complete eye protection and clothing protection. Avoid  
touching your eyes while working near batteries.  
10. 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.  
11. 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 an arc.

Basic Installation Procedures  
AC shore power  
A source of 120 V, 60Hz sine wave alternating current is needed to  
provide energy to charge batteries and pass power through to AC loads.  
This source is usually the utility grid (power company) or an AC  
generator. An automatic or manual AC source selector switch can be used  
to switch between the multiple sources of shore power to the Freedom  
HW system.  
The AC source feeding the Freedom HW must have the neutral conductor  
bonded to ground. When the inverter passes shore power through, it will  
lift the bonding relay on the output and will rely on the input being  
bonded in order to ensure that the power delivered to a sub panel is  
properly bonded. See “AC Output Neutral Bonding” on page 1–9 for  
more information on bonding relay operation.  
Important: Throughout this manual, the term “shore power” refers to AC  
input power from a utility grid, generator, or other AC source.  
Generator  
The Freedom HW is compatible with most generators which produce  
nominal 120 Vac 60Hz sine wave AC power.  
Since the DC charging current limit of the Freedom HW may be  
configured to provide as little as 7 A it is possible to use very small  
generators with the Freedom HW to charge batteries. The Freedom HW  
has been tested with generators of various sizes, including some as small  
as 700W.  
AC Disconnect  
and Over-  
Current  
Most safety requirements and electrical codes require the Freedom HW’s  
AC and DC inputs and outputs to be provided with over-current  
protection (such as circuit breakers or fuses) and disconnect devices.  
Protection  
Device  
AC Input: The circuit breaker or fuse (connected through hard  
wiring) that is used to supply the Freedom HW must be rated at no  
more than 30A and must be approved for use on 120 Vac branch  
circuits. The wire used between the breaker and the Freedom HW  
input must be sized adequately to carry current up to the rating of the  
input breaker and in accordance with the electrical codes or  
regulations applicable to your installation.  
975-0468-01-01  
1–7  
This guide for use by qualified installers only  
AC Output: The circuit breaker or fuse must be rated at no more than  
the rating of the input breaker in the installation and must be  
approved for use on 120 Vac branch circuits. The wire used between  
the Freedom HW and the AC output breaker must be of adequate size  
to match the AC input circuit breaker’s rating. The wiring from each  
AC output breaker to each of the loads must be adequately sized to  
carry the current rating of the individual AC output breaker.  
Disconnect Devices: Each system requires a method of  
disconnecting the AC circuits. If the over-current protection devices  
are circuit breakers, they will also serve as the disconnects. If fuses  
are used, separate AC disconnect switches will be needed ahead of  
the fuses. These will have to be a branch circuit rated for 120 Vac and  
have an appropriate current rating.  
AC Distribution  
Panels  
Most systems incorporate distribution centers both ahead of the Freedom  
HW (the AC source panel) and between the Freedom HW and the loads  
(the AC load panel). An AC source panel includes a main circuit breaker,  
which serves as over-current protection and as a disconnect for the AC  
shore power supply line. Additional circuit breakers serve individual  
circuits, one of which serves the Freedom HW. The AC load panel can  
incorporate an AC output circuit breaker and breakers for individual load  
circuits.  
CAUTION: Equipment damage  
Do not connect the output of the Freedom HW to what is known as a “multi-wire  
branch circuit”. These are four-wire circuits consisting of a ground, neutral, and  
two lines that are 180 degrees out of phase with each other (from a standard 120/  
240V “split phase” circuit). These circuits are commonly used in kitchens to  
power “split receptacles” where the top and bottom halves of a duplex receptacle  
are connected to different lines.  
AC Cabling  
AC cabling includes all the wires and connectors between the AC source  
and the Freedom HW, as well as all cabling between the Freedom HW  
and the AC output panels, circuit breakers, and loads. The type and size of  
the wiring varies with the installation and load. For example, in high  
vibration environments, such as RV applications, wire nuts may not be  
acceptable, so crimp splices would be required. In other applications,  
flexible multiple-strand wire may be required. Installation codes usually  
specify solid or stranded, overall size of the conductors, and type and  
temperature rating of the insulation around the wire.  
1–8  
975-0468-01-01  
This guide for use by qualified installers only  
Basic Installation Procedures  
AC breakers and fuses must be sized to adequately protect the wiring that  
is installed on the input and output AC circuits of the Freedom HW. All  
breakers and wiring must be sized and connected in accordance with the  
electrical codes or regulations applicable to your installation. Table 1-1  
gives some examples of wiring sizes based on the U.S. National Electrical  
Code and the Canadian Electrical Code. These examples are based on  
using a 2-conductor-plus-ground cable rated at 75 °C, and assuming an  
ambient temperature of up to 30 °C. Ensure that your breakers, and fuses  
have suitable temperature ratings for your wiring. Other codes and  
regulations may also be applicable to your installation.

Minimum Wire Size  
AC Output  
Neutral  
Bonding  
The neutral conductor of the Freedom HW’s AC output circuit (i.e., AC  
Output Neutral) is automatically connected to the safety ground during  
inverter operation. When the Freedom HW is using AC shore power, this  
connection is not present, so that the utility neutral (i.e., AC Input  
Neutral) is only connected to utility ground at your source. This conforms  
to National Electrical Code, which requires that separately derived AC  
sources (such as inverters and generators) to have their neutral conductors  
tied to ground in the same way that the neutral conductor from the utility  
is tied to ground in only one place. Check the regulations for your specific  
application to ensure that the installation will comply with the necessary  
requirements. In other words, the AC Input Neutral and Output Neutral  
must be isolated from each other.  
DC Cabling  
This includes all the cables and connectors between the batteries, the DC  
disconnect and over-current protection device, and the Freedom HW.  
Most mobile installations require multi-strand insulated cables for  
flexibility and durability in high vibration environments and require  
disconnects and over-current devices. Electrical wiring sizes are indicated  
by AWG notation. Under the AWG standard, a larger gauge number  
indicates a smaller wire diameter. Wire size is usually marked on the  
larger sized cables. Table 1-2 specifies the minimum recommended DC  
cable size and maximum fuse size for the Freedom HW. The DC cables  
must be copper and must be rated 75 °C minimum. The cables should  
be terminated with lugs that fit the DC stud terminals snugly (8 mm or  
5/16 in. hole size).

Note: Xantrex recommends not using a cable longer than 5 feet (1.5 meters) in each direction. Cable  
sizes above are based on the US National Electrical Code Table 310.17 - 75C cables, assuming an  
ambient temperature of 30 °C cables.  
Important: Using the correct cable size is critical to achieving the rated  
performance of the Freedom HW unit. When starting a heavy load the Freedom  
HW can draw current surges from the battery of up to 400A. If the DC wiring is  
too small the voltage drop from this surge will result in a voltage at the Freedom  
HW terminals that is too low for the Freedom HW to operate correctly. The  
Freedom HW may appear to operate correctly with smaller cables until a heavy  
load such as a microwave or refrigerator attempts to start - then the unit may  
work correctly sometimes and not work correctly other times.  
DCDisconnects  
and Over-  
Current Devices  
The DC circuit from the battery to the Freedom HW must be equipped  
with a disconnect and over-current device. This usually consists of a  
circuit breaker, a “fused-disconnect,” or a separate fuse and DC  
disconnect. Do not confuse AC circuit breakers with DC circuit breakers.  
They are not interchangeable. The rating of the fuse or breaker must be  
matched to the size of cables used in accordance with the applicable  
installation codes. The breaker or disconnect and fuse 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.  
Batteries  
The Freedom HW uses 12-volt battery banks. Every Freedom HW system  
requires a deep-cycle battery or group of batteries that provide the DC  
current that the Freedom HW converts to AC.

Basic Installation Procedures  
Ground Fault  
Circuit  
Interrupters  
(GFCIs)  
A GFCI is a device that de-energizes a circuit when a current to ground  
exceeds a specified value that is less than that required to blow the circuit  
breaker. GFCIs are intended to protect people from electric shocks and  
are usually required in wet or damp locations.  
Installations in recreational vehicles require GFCI protection of branch  
circuits connected to the AC output of the Freedom HW.  
The modified sine wave output of the Freedom HW is not equivalent to  
the waveform provided by electric utilities, and compliance with UL and  
CSA standards requires that Xantrex test and recommend specific GFCIs  
that will work correctly with the Freedom HW.  
For more information about GFCIs, see the application note "Using GFCI  
Receptacles on Xantrex Inverters and Inverter/Chargers" in the Document

Step 2: Choosing a Location for the Freedom HW  
WARNING: Fire and explosion hazard  
This equipment contains components that tend to produce arcs or sparks. To  
prevent fire or explosion, do not install the Freedom HW 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.  
WARNING: Fire hazard  
To reduce the risk of fire, do not cover or obstruct the ventilation openings. Do  
not install the Freedom HW in a zero-clearance compartment. Overheating may  
result.  
The Freedom HW should only be installed in locations that meet the  
following requirements:  
Dry. Do not allow water or other fluids to drip or splash on the  
Freedom HW. Do not mount the Freedom HW in an area subject  
to splashing water or bilge water.  
Cool. Normal air temperature should be between 21 °F and 165 °F  
(–20 °C and 60 °C)—the cooler the better.  
Ventilated. Allow at least 5 in. (13cm) of clearance at the DC end of  
the Freedom HW for air flow, 1 in. (2.5cm) on each side, and 2 in.  
(5cm) at the AC end. The more clearance for ventilation around the  
unit, the better the performance. Do not allow the ventilation  
openings on the ends of the unit to become obstructed.  
Safe. Do not install the Freedom HW in the same compartment as  
batteries or in any compartment capable of storing flammable liquids  
like gasoline.  
Close to the battery compartment and the AC source and load  
panels. Avoid excessive cable lengths (which reduce input and output  
power due to wire resistance). Use the recommended cable lengths  
and sizes, especially between the battery banks and the Freedom HW.  
Protected from battery acid and gases. Never allow battery acid to  
drip on the Freedom HW or its wiring when reading specific gravity  
or filling the battery. Also do not mount the unit where it will be  
exposed to gases produced by the batteries. These gases are very  
corrosive, and prolonged exposure will damage the Freedom HW.

Basic Installation Procedures  
Step 4: Connecting the AC Input Wires  
WARNING: Fire, Shock and Energy hazards  
Make sure wiring is disconnected from all electrical sources before handling. All  
wiring must be done in accordance with local and national electrical wiring  
codes. Do not connect the output terminals of the Freedom HW to any incoming  
AC source.  
General AC Wiring Considerations  
AC cable size  
The AC input cable may be either solid or stranded (as required), but must  
have three conductors and be sized as in Table 1-4 on page 1–16.  
AC Wiring  
Connectors  
Connect AC wires with crimp-on splice connectors.  
The amount of insulation you strip off individual wires will be specified  
by the connector manufacturer and is different for different types of  
connectors.  
AC and DC  
Wiring  
Separation  
Do not mix AC and DC wiring in the same conduit or panel. Where DC  
and AC wires must cross, make sure they do so at 90° to one another.  
Consult applicable codes for details about DC and AC wiring in close  
proximity to each other.  
AC Wiring  
For your reference, the AC Wiring Compartment is shown in Figure 1-5.  
Compartment  
AC Wiring  
To hard wire the Freedom HW AC input and output to an existing AC  
installation, read this section.  
AC wiring includes all the wires and connectors between the AC source  
and the Freedom HW and all wiring between the inverter, the AC panels,  
circuit breakers, and the GFCIs. The type and size of the wiring varies  
with the installation and load. For some RV applications, flexible  
multiple-strand wire is required.  
AC wiring must be sized appropriately to carry full load current on the  
input and output AC circuits in accordance with the electrical codes or  
regulations applicable to your installation. Table 1-4 is based on the U.S.  
National Electrical Code, 2003 Ed. and the Canadian Electrical Code,  
assuming 2-conductor-plus-ground cable, using 75 °C wiring, at an  
ambient temperature of 30 °C. Other codes and regulations may be  
applicable to your installation.

Step 5: Connecting AC Output to an Existing AC Circuit  
WARNING: Shock, fire, and energy hazards  
Make sure wiring is disconnected from all electrical sources before handling. All  
wiring must be done in accordance with applicable local and national electrical  
wiring codes.  
WARNING: Shock hazard and equipment damage  
Do not connect any AC source (such as a generator or utility power) to the  
AC wiring output of the Freedom HW.  
The Freedom HW will not operate if its output is connected to AC voltage from  
another source, and potentially hazardous or damaging conditions may occur.  
These conditions can occur even if the inverter is off.  
Do not connect the Freedom HW to an AC branch circuit that has  
high-power consumption loads.  
The Freedom HW will not operate electric heaters, air conditioners,  
stoves, and other electrical appliances that consume more than 1000  
watts.  
A Xantrex-tested and approved GFCI must be connected to the Freedom  
HW AC output, and on every receptacle connected to the AC hard wired  
installation. Other types may fail to operate properly when connected to  
the Freedom HW. Although you can reuse the factory-installed GFCI,

Basic Installation Procedures  
Step 6: Connecting the DC Cables  
CAUTION  
Before making the final DC connection, check cable polarity at both the battery  
and the Freedom HW. Positive must be connected to positive; negative must be  
connected to negative.  
Reversing the positive and negative battery cables will damage the Freedom HW  
and void your warranty. This type of damage is easily detected.  
WARNING: Fire hazard  
Use only copper wire rated 75 °C minimum. Make sure all DC connections are  
tight to a torque of 108–120 in-lbf (12.2–13.6 N-m). Loose connections will  
overheat.  
Follow the procedure given below to connect the battery leads to the  
terminals on the DC end. The 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. Table 1-2  
on page 1–10 specifies the minimum DC cable size and maximum fuse  
size for the Freedom HW.  
Do not route your DC cables through an electrical distribution panel,  
battery isolator, or other device that will cause additional voltage drops.  
Figure 1-8 DC End  
975-0468-01-01  
1–23  
This guide for use by qualified installers only  
   
To make the DC connections  
1. Make sure the inverter is off and no AC or DC is connected to the  
unit.  
2. Remove the nuts and washers from the Freedom HW positive and  
negative DC terminals.  
3. Strip 1/2 inch (13 mm) to 3/4 inch (19 mm) insulation from one end  
of each cable. The amount stripped off will depend on the terminals  
chosen.  
4. Attach the connectors that will secure the cables to the battery, to the  
disconnect/battery selector switch, and the fuse block. The connectors  
you use must create a permanent, low-resistance connection.  
If crimp connectors are required, Xantrex recommends using  
approved and certified connectors, and to use the tool recommended  
by the terminal manufacturer. Make sure no stray wires protrude from  
the connector or terminal.  
(You may find it more convenient to have the crimp connectors  
attached by the company that sells you the cable and/or connectors.)  
5. For each cable end that will be connected to the inverter, strip 1/2 inch  
(13 mm) to 3/4 inch (19 mm) of insulation from the cable. The  
amount stripped off will depend on the terminals chosen.  
6. Attach the connector that will join the cable to the inverter DC  
terminal.  
7. Install a fuse and fuse holder in the cable that will be used for the  
positive side of the DC circuit.  
The fuse must:  
be as close to the battery positive terminal as possible,  
be rated for DC circuits,  
have an Ampere Interrupting Capacity (AIC) that exceeds the  
short-circuit current available from the battery (i.e., Class T fuse).  
8. To prevent sparking when making the connection, ensure the  
disconnect/battery selector switch is off.  
9. Attach the connector on the positive cable to the positive DC terminal  
on the inverter.

Basic Installation Procedures  
10. Install the lock washer and nut that are supplied with the inverter.  
Tighten the nut to a torque of 108–120 in-lbf (12.2–13.6 N-m). Make  
the connection snug enough so the ring terminal does not move  
around on the DC terminal, but do not overtighten. See Figure 1-9,  
CAUTION  
Loose connections cause excessive voltage drop and may cause overheated wires  
and melted insulation.  
CAUTION  
Do not over-tighten the nut on the DC input terminals. Damage to the DC input  
terminals may result.  
The maximum torque setting is 120 in-lbf (13.6 N-m).  
CAUTION: Reverse polarity  
DC power connections to the Freedom HW must be positive to positive and  
negative to negative.  
A reverse polarity connection (positive to negative) will blow a fuse in the  
inverter and may permanently damage the inverter. The fuse is not user  
replaceable and the inverter may need to be returned for servicing.  
Damage caused by a reverse polarity connection is not covered by your warranty.  
11. Before proceeding, double check that the cable you have just installed  
connects the positive DC terminal of the inverter to the disconnect/  
battery selector switch, fuse holder, and that the other end of the fuse  
holder is connected to the positive terminal of the battery.  
.
WARNING: Explosion or fire  
Do not complete the next step if flammable fumes are present. Explosion or fire  
may result if the disconnect/battery selector switch is not in the off position.  
Thoroughly ventilate the battery compartment before making this connection.  
12. Connect the cable from the negative post of the battery to the negative  
DC terminal of the inverter.

DC Grounding  
To connect the DC ground:  
The equipment grounding lug on the DC end of the Freedom HW is used  
to connect the chassis of the Freedom HW to your system’s DC negative  
connection or grounding bus point as required by electrical regulations.  
Use copper wire that is either bare or provided with green insulation. Do  
not use the DC Ground Lug for your AC grounding. (See the AC wiring  
instructions in this section.)  
Follow the guidelines below that correspond to the specific type of  
installation. These guidelines assume you are using the DC supply cable  
and fuse sizes recommended in this manual. If you are using different  
sizes, refer to the applicable installation code for DC grounding details.  
Recreational  
Vehicle  
Use 8AWG copper wire and connect it between the Chassis Ground lug  
and the vehicle’s DC grounding point (usually the vehicle chassis or a  
dedicated DC ground bus).

Basic Installation Procedures  
Step 7: Mounting the Display Panel  
Xantrex has three communications cables of different lengths available  
for purchase. Choose a 25-foot cable (p/n: 31-6257-00), 50-foot cable  
(p/n: 31-6262-00), or a 70-foot cable (p/n: 31-6275-00).  
Flush mounting the panel on a wall or bulkhead requires an opening  
specified in the display panel mounting template. About 1.5 inches (3.8  
cm) of free space is required within the wall to accommodate the depth of  
the panel. Be sure there is no wiring or other obstructions within the wall  
before you make an opening.  
To mount the display panel:  
1. Choose a location that is dry, out of direct sunlight, free from  
corrosive or explosive fumes, and otherwise appropriate for mounting  
an electronic device.  
2. Remove the display panel from Freedom HW.  
3. Pilot-drill the corner holes using the display panel mounting template  
and cut out the hole in which the display panel will be inserted.  
4. Position the display panel mounting plate over the hole and fasten it  
to the wall using all four screws in all the corners of the mounting  
plate.  
5. Route the communications cable(s) inside the wall and through the  
mounting plate opening.  
6. Insert the cable’s connector (the one through the opening) in the jack  
on the backside of the display panel.  
7. Place the display panel through the opening of the mounting plate and  
secure it with two screws – one for each side.  
8. Route the communications cable to the Freedom HW’s display panel  
compartment and insert the other connector in the jack located near  
the battery select dip switch.  
9. Install the display panel compartment cover over the compartment  
and secure it with two screws – one for each side.  
Important: Do not route the communications cable in parallel and in conduit  
with the AC and DC wires. In situations where the cable must cross with the AC  
and DC wires, make sure they cross at a 90° angle to each other.

Step 8: Testing Your Installation  
WARNING: Shock hazard  
Pressing the Inverter button to turn OFF the Freedom HW inverter function on  
display panel does not disconnect DC or AC input power to the Freedom HW. If  
shore power is present at AC input terminals, it will pass through to the AC  
output.  
There are two tests to be performed. The first test verifies that the  
Freedom HW is inverting DC battery power and delivering AC power to  
its output.  
The second test is intended for installations where AC input and output is  
hard wired to the Freedom HW. This test verifies that the Freedom HW  
transfers from inverter power to shore power when shore power is  
present.  
Note: Shore power (pass-through) refers to the AC input power from a utility  
grid, generator or external AC source.  
When you are ready to test your installation and operate the Freedom  
HW, close the DC fuse and Disconnect or the DC circuit breaker to  
supply DC power to the Freedom HW.  
Testing in Invert Mode  
To test the Freedom HW in invert mode:  
1. For hard wired installations, ensure shore power is not present.  
2. Press the Inverter button to turn the inverter on.  
The status LED on the display panel glows yellow and the LED  
display illuminates.  
3. Plug an appliance within the power rating of the inverter into the AC  
outlet hard wired to the Freedom HW.  
4. Turn the appliance on to verify that it operates.  
If the appliance operates, your installation is successful. If your  
installation has AC input hard wired to the Freedom HW, proceed to  
If the status LED on the display panel glows red, see the Troubleshooting  
chapter.

Basic Installation Procedures  
Testing in Shore Power Mode  
To test the Freedom HW in shore power mode:  
With the appliance from the previous test still connected and  
operating, connect the shore power source.  
The Freedom HW transfers the appliances to shore power. The status  
LED on the display panel will change from yellow to a ten-second  
flashing yellow and then green.  
If the appliance operates, your installation is successful.  
Note: If the Inverter button on the Freedom HW is set to Standby, the Freedom  
HW will automatically supply the appliances with inverter power if the shore  
power source fails or becomes disconnected or the shore power voltage is too low  
(less than 95 volts AC).  
WARNING: Shock hazard  
Whether or not the Inverter button is turned ON, shore power will pass through  
the Freedom HW to the output when shore power is within normal operating  
range.

Charger Output Current vs. AC Input Voltage  
Charger Output Current vs. AC Input Voltage  
When the Freedom HW is charging batteries from a weak shore power  
source the AC voltage may fall as the Freedom HW draws current. To  
reduce the chance of the shore power voltage collapsing below the  
configured transfer level the Freedom HW will reduce the charging  
current at low shore power voltage according to the following graph:
