6 Freedom HF Installation Guide
AC shore power
Basic Installation Procedures
AC Disconnect and Over-Current Protection Device
A source of 120 volts, 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 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 9 for more information on
bonding relay operation.
IMPORTANT:
AC input power from a utility grid, generator, or other AC source.
Throughout this manual, the term “shore power” refers to
Generator
The Freedom HF is compatible with most generators which produce
nominal 120 volts AC 60Hz sine wave AC power.
Since the DC charging current limit of the Freedom HF may be configured
to provide as little as 2 amps 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 700 watts.
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.
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 volts AC 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.
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 volts AC 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 volts AC and have an appropriate current rating.
This guide for use by qualified installers only.
975-0395-01-01 7
Basic Installation Procedures
Failure to follow these instructions can damage the unit and/or
damage other equipment.
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.
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 and size of the
wiring varies with the installation and load. For example, in high vibration
environments, such as marine or 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.
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. T able 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 2conductor-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.

AC Output Neutral Bonding
Basic Installation Procedures
DC Cabling
The neutral conductor of the Freedom HF’s AC output circuit (i.e., AC
Output Neutral) is automatically connected to the safety ground during
inverter operation. When AC utility power is present and the Freedom HF 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.
AC Grounding
As per UL458 SA29.5, for all grounded AC cord-connected marine
inverter/chargers: The Freedom HF 1055 EMS and the Freedom HF 1800
EMS should be grounded to reduce risk of electric shock. Make sure that
the three-prong plug is plugged into properly installed and grounded AC
wall outlet in accordance with all local codes and ordinances.
As per UL458 SA29.5, for all permanently connected marine inverter/
chargers: The rest of the Freedom HF models should be connected to a
grounded, metal, permanent wiring system. Also, make sure that an AC
ground wire is connected to the AC ground terminal on the unit. Do not just
connect the line and neutral wires.
All connections to a unit should comply with all local codes and ordinances.
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 flexibi lity and
durability in high vibration environments and require disconnects and overcurrent 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 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).

Basic Installation Procedures
IMPORTANT:
performance of the Freedom HF unit. When starting a heavy load the
Freedom 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 som etimes and not work
correctly other times.
Using the correct cable size is critical to achieving the rated
DC Disconnects and Over-Current Devices
The DC circuit from the battery to the Freedom HF 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 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.
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 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. Here are the recommendations:

Step 2: Choosing a Location for the Unit
Failure to follow these instructions can result in death or serious
injury.
FIRE AND EXPLOSION HAZARDS
• This equipment contains components that tend to produce arcs or
sparks. To prevent fire or explosion, do not in stall the Freedom HF 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.
• 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.
Basic Installation Procedures
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 moun t 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 Unit
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” in the Owner’s Guide.
2. Select an appropriate mounting location and orientation. (See Figure 2
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.
• On a horizontal surface (see 3)

Step 4: Connecting the AC Input Wires
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 HF to any incoming AC source.
General AC Wiring Considerations
AC Wiring Connectors Where applicable, 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 and GFCIs Y ou can plug loads (12 amps continuous,
15 amps 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 21.
AC wiring includes all the wires and connectors between the AC source and
the Freedom HF and all wiring between the inverter, th e AC panel s , circuit
breakers, and the GFCIs. The type and size of the wiring varies with the
installation and load. For some RV applica ti ons, 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. Table4 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.

Basic Installation Procedures
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, six-wire telephone extension cable.
Flush mounting the panel on a wall or bulkhead 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 corro sive
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:
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.
Do not route the communications cable in parallel and in

Step 8: Testing Your Installation
Failure to follow these instructions can result in death or serious
injury.
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.
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 HF,
close the DC fuse and Disconnect or the DC circuit breaker to supply DC
power to the Freedom HF.
Basic Installation Procedures
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.
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
Freedom HF GFCI or an AC outlet hard wired to the Freedom HF.
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.
This guide for use by qualified installers only.
975-0395-01-01 29
Basic Installation Procedures
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.
NOTE: 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

The drip shield helps to protect the unit from dripping or splashing liquids,
which will cause a shock hazard. Drip shields are especially useful in
marine installations where water from condensation, rain, or sea may come
into contact with the Freedom HF.
SHOCK HAZARD
This product is intended only for use in dry areas. Operating the unit
under wet conditions may expose you to a shock hazard. Installing drip
shields may not entirely protect you from this hazard. Do not operate the
unit when it is wet.
