Precautions When Working With Batteries  
5. Use extra caution to reduce the risk or dropping a metal tool on the  
battery. It could spark or short circuit the battery or other electrical  
parts and could cause an explosion.  
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE  
AND EXPLOSION FROM VENTED GASES HAZARDS  
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.  
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.  
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.  
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.  
NOTES:  
1. Mount and place the Freedom HF 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.

Ignition Control The Freedom HF features the ability to inhibit  
the inverter from operating in the absence of a voltage signal from a  
vehicle's ignition circuit. This is particularly useful if the inverter is  
required to operate only when a vehicle's engine is running.  
a.Near-zero or dead batteries can be recharged. However, some batteries which have  
been left uncharged for days can become severely damaged thus, recharging is futile.  
b.Available on the Freedom HF 1055 EMS model and Freedom HF 1800 EMS model.  
The inverter/charger features a 20-amp fused and switched output voltage supplied  
from the inverter/charger's positive terminal. When connected to a vehicle's ignition  
signal, a switched positive voltage is available to power auxiliary circuits that are re-  
quired to operate only when the vehicle is operational.

To change the inverter mode setting:  
To adjust the alarm setting:  
By default the inverter mode is set to ON (“”).  
By default the alarm is set to ON.  
ON (“”) will put the inverter on standby. This means when shore  
power is present, AC shore power will pass through as AC output.  
And when shore power is not available, the inverter function will  
take power from the battery and provide AC output power. When  
the inverter mode is ON, you can manually turn the inverter  
function ON or OFF by using the Inverter Power button. See  
ON (“”) will sound the alarm on all warning and fault  
conditions.

as AC output. However, when shore power is not available, the  
inverter function remains disabled and therefore no AC output  
power. When the inverter mode is OFF, you cannot manually turn  
the inverter function ON or OFF by using the Inverter Power button.  
The LED screen will display the present (or most recent) alarm  
setting. Example, “” for an inverter mode setting of ON.

HF’s Inverter function ON and OFF. To operate, press the button  
and hold for one second.  
When the Freedom HF’s Inverter function is turned off (“”) and  
the AC source is outside the operating range or is disconnected, the  
Freedom HF will not switch to invert mode. This means that even if  
the Inverter Power button is pressed to try and turn inverter function  
on, there will be no power coming from the battery to the AC output  
terminals. Therefore, any appliance connected to the AC output  
terminals will not operate.  
When shore power is NOT present and Inverter mode is ON:  
the AC outlets will supply power to any attached appliances  
when the Inverter Power button is turned ON and  
the AC outlets will not supply power to any attached appliances

Energy Saver 25-hour Automatic Shut Off  
ELECTRICAL SHOCK HAZARD  
During invert mode, a 25-hour countdown is initiated when the AC  
load drops to less than approximately 80 watts and remains below  
this level. After 25 hours the inverter automatically shuts off to  
reduce battery discharge and preserve battery life.  
Turning the Inverter mode setting to OFF and/or turning the  
Inverter Power button off do not disconnect DC battery power  
from the Freedom HF. You must disconnect both AC and DC  
power before working on any circuits connected to the Freedom  
HF.  
Failure to follow these instructions can result in death or serious  
injury.  
To prevent unnecessary battery discharge, turn the Inverter Power  
button off when you are not using the Freedom HF.

Operating in Shore Power Mode  
Checking Battery Status  
Checking Output Power  
During inverter mode, you can check the battery status by pressing  
the Select button until the Input Voltage LED (or Input Current  
LED) illuminates. The battery voltage (or battery current) appears  
in the three-digit LED display screen when the Input Voltage LED  
(or Input Current LED) illuminates.  
During Inverter mode, you can check how much power (displayed  
in kW) the Freedom HF is supplying to the connected loads by  
pressing the Select button until the Output Power LED illuminates.  
Operating Several Loads at Once  
The normal operating battery voltage range is between 11 and 15  
volts.  
If you are going to operate several loads from the Freedom HF, turn  
them on one at a time after you have turned the inverter on.  
Turning loads on separately helps to ensure that the inverter does  
not have to deliver the starting current for all the loads at once, and  
will help prevent an overload shutdown.  
Turning the Audible Alarm ON or OFF  
The Freedom HF’s audible alarm can be turned ON or OFF. Any  
warnings such as fault conditions or imminent shutdown are both  
displayed on the display panel’s screen and sounded on the alarm  
speakers.  
It is not possible to turn OFF the screen and prevent it from  
displaying error codes but it is possible to turn OFF the audible  
alarm.  
NOTE: The alarm setting will reset to its default setting when the  
Freedom HF’s Inverter Power button is turned OFF then turned ON again.

Transitioning from Inverter Mode to Shore  
Power  
When the unit is operating in inverter mode and shore power  
becomes available, the Freedom HF begins a 20-second countdown  
to verify the stability of the shore power. If shore power remains  
stable within 20 seconds, at the end of the countdown, the Freedom  
HF has less than 30 milliseconds to switch to shore power mode and  
start drawing power from the AC source.  
The Status LED will turn from solid YELLOW to flashing  
YELLOW during the 20-second countdown, then turn to GREEN  
when battery power is transitioned successfully to shore power.

Operating During Transition Between Shore Power and Inverter Mode  
Inverter Loads  
The Freedom HF will operate most AC loads within its power rating LED turns solid RED and in 30 seconds, both the unit and the  
of 1000 watts (Freedom HF 1000), 1500 watts (Freedom HF 1500), display screen will shut down to prevent damage to the inverter and  
or 1800 watts (Freedom HF 1800). However, some appliances and  
equipment may be difficult to operate, and other appliances may  
actually be damaged if you try to operate them with the Freedom  
protect the battery from being over-discharged.  
High Surge Loads  
Some induction motors used in freezers, pumps, and other motor-  
operated equipment require high surge currents to start. The  
Freedom HF may not be able to start some of these motors even  
though their rated steady state current draw is within the inverter’s  
limits. The unit will shut down and indicate an overload shutdown.  
Overload Conditions  
There are two kinds of overload conditions:  
an overload warning  
an overload shutdown  
Over-temperature Conditions  
Overload Warning When the Freedom HF’s AC load is  
approximately 100 W below the overload shutdown limit of  
~1000 W (Freedom HF 1000) and ~1800 W (Freedom HF 1500/  
1800), the audible alarm beeps once every two seconds and the  
display screen shows a fault code .  
During Inverter mode, when the Freedom HF’s internal temperature  
starts to approach its preset shutdown limit, the alarm will beep  
every two seconds and the display will show fault code . If the  
over-temperature condition persists, the alarm will beep once per  
second and the display will show fault code . The Status LED  
turns solid RED and the inverter will shut down to prevent damage  
to the inverter and protect the battery from being over-discharged.  
Overload Shutdown When the Freedom HF’s AC load increases  
to near ~1100 W (Freedom HF 1000 models) and ~2000 W  
(Freedom HF 1500/1800 models), the audible alarm beeps every  
second and the display screen shows a fault code . The Status

Operating During Transition Between Shore Power and Inverter Mode  
However, when the internal temperature drops and falls within  
normal operating temperature, the Freedom HF will recover  
automatically and will continue inverting.  
Trouble Loads  
During AC shore power mode, when the Freedom HF’s charger  
temperature starts to approach its limit, the charging current will be  
reduced to 10 amps (Freedom HF 1000 models) or 20 amps  
(Freedom HF 1500/1800 models).  
EQUIPMENT DAMAGE  
Some equipment may be damaged by the Freedom HF’s modified  
sine wave output, which has a different wave form than utility-  
supplied electricity.  
The Freedom HF also monitors the internal transfer relay  
temperature. It automatically turns on the fan when the relay starts  
to approach its preset temperature limit and turns off when it cools  
down. If the relay exceeds its preset temperature limit, the display  
shows a fault code . See “To reset error codes  to :” on  
Failure to follow these instructions can damage the unit and/or  
damage other equipment.  
Some appliances, including the types listed below, may be damaged  
if they are connected to the Freedom HF:  
Speed controllers found in some fans, power tools, kitchen  
appliances, and other loads may be damaged.  
Some chargers for small rechargeable batteries can be  
Metal halide arc (HMI) lights can be damaged.  
IMPORTANT: If you are unsure about operating any device with the  
Freedom HF, contact the manufacturer of the device to ensure that it is  
compatible with the modified sine waveform.

Battery Charging  
Battery charging is possible only when shore power is present and  
the Freedom HF unit is connected to a battery (or battery bank).  
NOTE:  
If an external DC load is  
connected to the  
battery and it drains the  
battery down to 12.8  
Vdc, the charger will  
start a new bulk stage.  
Voltage  
The frequency of battery charging is determined by how much  
energy in the battery is used up during inverting. Whenever the  
Freedom HF detects a battery voltage that falls below 12.8 volts, the  
unit will begin charging the battery, i.e., enter into bulk and  
absorption stages then settle in float stage. If battery voltage does  
not reach 5 volts after one minute or 10 volts after 15 minutes as  
shown in the graph, the unit will terminate the charging process and  
the error code  will show on the display screen.

Routine Maintenance  
Freedom HF Unit  
Minimal maintenance is required to keep your Freedom HF  
operating properly. Periodically you should:  
Clean the exterior of the unit with a damp cloth to prevent the  
accumulation of dust and dirt.  
Ensure that the DC cables are secure and fasteners are tight.  
Make sure the ventilation openings are not clogged.  
Batteries  
When possible, you should recharge your batteries whenever a low  
voltage warning or a shutdown occurs with the Freedom HF. This  
gives the batteries a much longer life than recharging when the  
batteries have been almost completely discharged.

Common Problems  
3. Keep the cables between the battery and the Freedom HF as  
short as possible, and twist them together with two to three  
twists per foot. (This minimizes radiated interference from the  
cables.)  
Buzz in Audio Equipment  
Some inexpensive stereo systems may emit a buzzing noise from  
their loudspeakers when operated from the Freedom HF. This  
occurs because the power supply in the audio system does not  
adequately filter the modified sine wave produced by the inverter.  
The only solution is to use a sound system that has a higher quality  
power supply.  
4. Move the television as far away from the Freedom HF as  
possible.  
5. Do not operate high power loads with the Freedom HF while

When the Freedom HF is operating, it can interfere with television  
reception on some channels. If interference occurs, try the  
following:  
1. Make sure that the chassis ground stud on the Freedom HF is  
solidly connected to the ground system of your vehicle or  
vessel.  
2. Make sure that the television antenna provides an adequate  
(“snow-free”) signal, and that you are using good quality cable  
between the antenna and the television.

Inverter Applications  
The Freedom HF performs differently depending on the AC loads  
connected to it. If you are having problems with any of your loads,  
read this section.  
Universal motors are generally easier to start. Since motor  
characteristics vary, only testing will determine whether a specific  
load can be started and how long it can be run.  
If a motor fails to start within a few seconds or loses power after  
running for a time, it should be turned off. When the inverter  
attempts to start a load that is greater than it can handle, it will turn  
itself off after a few seconds.  
Resistive Loads  
These are the loads that the inverter finds the simplest and most  
efficient to drive. Voltage and current are in phase (i.e. in step with  
one another). Resistive loads usually generate heat in order to  
accomplish their tasks. Toasters, coffee pots, and incandescent  
lights are typical resistive loads. It is usually impractical to run  
larger resistive loads—such as electric stoves and water heaters—  
from an inverter due to their high current requirements. Even  
though the inverter can most likely accommodate the load, the size  
of battery bank required would be impractical if the load is to be run  
for long periods.  
Long Transfer Times  
A specific situation has been observed where the Freedom HF may  
take a long time (~ 0.1–0.2 seconds) to transfer to inverter mode  
when shore power fails. This can occur when the Freedom HF is  
used to power motor loads where the motor is able to “freewheel”  
when power is removed (for example, a grinder). This long transfer  
may cause connected computers or other sensitive equipment to  
operate incorrectly. To avoid this effect, it is recommended not to  
connect motor loads together with sensitive equipment to the  
inverter for power.  
Motor Loads  
Induction motors (motors without brushes) require two to six times  
their running current on start up. The most demanding are those that  
start under load (e.g. compressors and pumps). Of the capacitor start  
motors (typical in drill presses, band saws, etc.), the largest you can  
expect to run is 1/2 to 1 hp (the transfer relays are rated at 2 hp).
