RECAUTIONS
P
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.

Precautions for Using Rechargeable Appliances
CAUTION: Equipment damage
Most rechargeable battery-operated equipment uses a separate charger or
transformer that is plugged into an AC receptacle and produces a low
voltage charging output.
Some chargers for small rechargeable batteries can be damaged if
connected to the Freedom HF. Do not use the following with the Freedom
HF:
• Small battery-operated appliances like flashlights, razors, and night
lights that can be plugged directly into an AC receptacle to recharge.
• Some chargers for battery packs used in power hand tools. These
affected chargers display a warning label stating that dangerous
voltages are present at the battery terminals.
Important:
the Freedom HF, contact the equipment manufacturer to find out if the appliance
is acceptable for use with modified sine wave input voltage. See the detailed
description of the Freedom HF waveform in Appendix A, “Specifications” under
“Electrical Specifications: Inverter Mode” on page A–2.

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 HF
system.
The AC source feeding the Freedom HF 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.
Basic Installation Procedures
Important:
input power from a utility grid, generator, or other AC source.
Throughout this manual, the term “shore power” refers to AC
Generator The Freedom HF is compatible with most generators which produce
nominal 120 Vac 60Hz sine wave AC power.
Since the DC charging current limit of the Freedom HF may be
configured to provide as little as 2A it is possible to use very small
generators with the Freedom HF to charge batteries. The Freedom HF has
been tested with generators of various sizes, including some as small as
700W.
AC Disconnect
and OverCurrent
Most safety requirements and electrical codes require the Freedom HF’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 HF 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 HF
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.

FreedomHF_IC_01-Installation.fm Page 8 Monday, December 24, 2007 9:47 AM
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 HF 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
HF (the AC source panel) and between the Freedom HF 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 HF. 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 HF 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 HF, as well as all cabling between the Freedom HF and
the AC output panels, circuit breakers, and loads. The type an d size of the
wiring varies with the installation and load. For example, in high
vibration environments, such as marine or R V 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.

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 HF. 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 cabl e 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.

is charging, 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 HF. 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 HF. 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).

HF 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
HF terminals that is too low for the Freedom HF to operate correctly. The
Freedom HF 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.
Using the correct cable size is critical to achieving the rated

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 HF uses 12-volt battery banks. Every Freedom HF system
requires a deep-cycle battery or group of batteries that provide the DC
current that the Freedom HF converts to AC.

(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 marine and recreational vehicles require GFCI protection
of branch circuits connected to the AC output of the Freedom HF.
The modified sine wave output of the Freedom HF 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 HF.

Step 2: Choosing a Location for the Freedom HF
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 HF in compartments
containing batteries or flammable materials, or in locations that require ignitionprotected 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 HF in a zero-clearance compartment. Overheating may
result.
The Freedom HF 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 HF. Do not mount the Freedom HF in an area subject to
splashing water or bilge water.
❐ Cool. Normal air temperature should be between 32 °F and 104 °F
(0 °C and 40 °C)—the cooler the better.
❐ Ventilated. Allow at least 5 in. (13cm) of clearance at the DC end of
the Freedom HF 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 HF 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 HF.
❐ Protected from battery acid and gases. Never allow battery acid to
drip on the Freedom HF 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 HF.

Step 3: Mounting the Freedom HF
To mount the Freedom HF:
1. Remove the Freedom HF from its shipping container, verify that all
components are present, and record relevant product information on
“Information About Your System” on page WA–4.
2. Select an appropriate mounting location and orientation. (See Figure
1-3 below.) To meet regulatory requirements, for use in on-land
applications, the Freedom HF must be mounted in one of the
following orientations:
• Under a horizontal surface (see 1)
• In a horizontal position on a vertical surface (see 2)
Note: For marine installations, only this orientation is allowed,
due to the probability of moisture finding access into the
enclosure.
Basic Installation Procedures
• On a horizontal surface (see 3)
See page 1–31 for drip

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.
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.
For your reference, the AC Wiring Compartment is shown in Figure 1-5.
You can plug loads (12 A continuous, 15 A maximum) directly into the
GFCI receptacle on the front panel of the Freedom HF. You can also
connect the inverter to an existing AC installation and then plug loads into
GFCI receptacles connected to that circuit.
If you plan to use the Freedom HF with the GFCI installed on the unit,
proceed to “Step 6: Connecting the DC Cables” on page 1–24.
If you plan to hard wire the Freedom HF 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 HF 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.

Step 6: Connecting the DC Cables
CAUTION
Before making the final DC connection, check cable polarity at both the battery
and the Freedom HF. Positive must be connected to positive; negative must be
connected to negative.
Reversing the positive and negative battery cables will damage the Freedom HF
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 216–240 inch-pounds (24–27Nm). 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 HF.
Do not route your DC cables through an electrical distribution panel,

To make the DC connections
Refer to Figure 1-9.
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 HF 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. Thread a supplied DC terminal cover over the positive and negative
cables. The red cover goes on the positive cable; the black cover on
the negative cable.
Basic Installation Procedures
7. Attach the connector that will join the cable to the inverter DC
terminal.
8. 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).

9. To prevent sparking when making the connection, ensure the
disconnect/battery selector switch is off.
10. Attach the connector on the positive cable to the positive DC terminal
on the inverter.
11. 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,
“DC Cable Connections” on page 1–27.
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 HF 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.
12. 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.
13. Connect the cable from the negative post of the battery to the negative
DC terminal of the inverter.

15. Slip the DC terminal covers over the Freedom HF DC terminals.
Basic Installation Procedures
DC Grounding
Figure 1-9
DC Cable Connections
To connect the DC ground:
The equipment grounding lug on the DC end of the Freedom HF is used
to connect the chassis of the Freedom HF 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).
Marine Use copper wire that is bare or has insulation rated min.
•
°C, and connect it between the Chassis Ground lug and the boat’s
105
DC grounding bus or engine negative bus. For the Freedom HF 1000,
use a wire of gauge 4AWG minimum. For the Freedom HF 1800, use
a wire of gauge 1/0AWG minimum.

Step 7: Mounting the Display Panel
The communications cable supplied with the display panel is 25 feet (7.62
meters) long. If you want to replace the cable with one that is shorter, use
a high quality, 6-wire telephone extension cable.
Flush mounting the panel on a wall, bulkhead, or panel requires an
opening that is approximately 3.25 × 1.25 inches (8.25 × 3.18 cm). About
1.5 inches (3.81 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. Tape the mounting template (in the Freedom HF package) to the
mounting surface and mark the locations of the mounting holes and
the area to be cut away.
3. Pilot-drill the mounting holes and cut out the hole in which the panel
will be inserted.
4. Route the communications cable(s) inside the wall and through the
opening.
5. Insert one of the cable’s connectors in either jack on the bottom of the
panel.
6. Place the panel in the opening and secure it with appropriate
fasteners.
7. Route the communications cable to the Freedom HF and insert the
connector in the jack located near the battery select dip switch.
Important:
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.
Do not route the communications cable in parallel and in conduit

Step 8: Testing Your Installation
WARNING: Shock hazard
Pressing the Inverter button to turn OFF the Freedom HF inverter function on
display panel does not disconnect DC or AC input power to the Freedom HF. 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 HF 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 HF. This test verifies that the Freedom HF
transfers from inverter power to shore power when shore power is
present.
Basic Installation Procedures
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 op erate the Freedom HF,
close the DC fuse and Disconnect or the DC circuit breaker to supply DC
power to the Freedom HF.
Testing in Invert Mode
To test the Freedom HF in invert mode:
1. For hard wired installations, ensure shore power is not present.
2. Press the Inverter button to turn the inverter on.
3. Plug an appliance within the power rating of the inverter into the
4. Turn the appliance on to verify that it operates.
If the appliance operates, your installation is successful. If your
installation has AC input and output hard wired to the Freedom HF,
proceed to “Testing in Shore Power Mode”.
If the status LED on the display panel glows red, see the Troubleshooting
chapter.
The status LED on the display panel glows yellow and the LED
display illuminates.
Freedom HF GFCI or an AC outlet hard wired to the Freedom HF.

FreedomHF_IC_01-Installation.fm Page 30 Monday, December 24, 2007 9:47 AM
Testing in Shore Power Mode
To test the Freedom HF in shore power mode:
◆ With the appliance from the previous test still connected and
operating, connect the shore power source.
The Freedom HF 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 HF is turned ON, the Freedom HF
will automatically supply the appliances with inverter power if the shore power
source fails or becomes disconnected.
If the Inverter button on the Freedom HF is turned ON and shore power voltage is
too low (less than 90 volts AC), the unit will transfer to inverter power to continue
running your appliances.
WARNING: Shock hazard
Whether or not the Inverter button is turned ON, shore power will pass through
the Freedom HF to the output when shore power is within normal operating
range.
