NOTE: During charging, the display will go into sleep mode and will not show the percentage of charge or voltage of the battery. To turn the display back on, press the Display button.
DISPLAY MODE BUTTON
Use this button to set the function of the digital display to one of the following:

• Battery % – The digital display shows an estimated charge percentage of the battery connected to the charger’s battery clamps.
• Alternator % – The digital display shows an estimated output percentage of the vehicle’s charging system connected to the charger’s battery clamps, compared to a properly functioning system. The alternator percent range is from 0 to 100%. Readings below 0 (13.2 volts) will read LOW and readings above 100% (14.6 volts) will read  HIGH. If you get a HIGH or LOW reading, have the electrical system checked by a qualified technician.
• Voltage – The Digital Display shows the voltage at the charger battery clamps, in DC volts, prior to charging. During charging, it shows the auto-detected battery charge voltage.

RATE SELECTION BUTTON
Use this button to select one of the following:

• 6A<>2A CHARGE/MAINTAIN – For charging small and large batteries. Not recommended for industrial applications.
•  40<>15A BOOST – For quickly adding energy to a severely discharged or large capacity battery prior to Engine Start. The unit will automatically switch to 6A<>2A Charge/Maintain after the Boost operation has been completed.
• 125A ENGINE START – Provides additional amps for cranking an engine with a weak or run-down battery. Always use in combination with a battery.

NOTE: Once the charger has started charging the battery, if you press the Rate Selection button once, the output current is shut off and the display show OFF and then the battery voltage.  If you press the Rate Selection button again, the current will go back on at the same setting it was when it was turned off.

LED INDICATORS
CLAMPS REVERSED (red) LED flashing: The connections are reversed.
CHARGING (yellow/orange) LED lit: The charger is charging the battery.
CHARGING (yellow/orange) LED flashing: The charger is in abort mode.
CHARGED/MAINTAINING (green) LED pulsing: The battery is fully charged and the charger is in maintenance mode.
NOTE: See the Operating Instructions section for a complete description of the charger modes.

BATTERY TYPE BUTTON
Use this button to set the type of battery.

• STANDARD – Used in cars, trucks, and motorcycles, these batteries have vent caps and are often marked “low maintenance” or “maintenance-free”. This type of battery is designed to deliver quick bursts of energy (such as starting engines) and has a greater plate count. The plates are thinner and have somewhat different material compositions. Standard batteries should not be used for deep-cycle applications.
• AGM – The Absorbed Glass Mat construction allows the electrolyte to be suspended in close proximity with the plate’s active material. In theory, this enhances both the discharge and recharge efficiency. The AGM batteries are a variant of Sealed VRLA (valve-regulated lead-acid) batteries. Popular uses include high-performance engine
  starting, power sports, deep-cycle, solar and storage batteries.
• GEL – The electrolyte in a GEL cell has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than those for other styles of lead-acid battery. This is probably the most sensitive cell in terms of adverse reactions to over-voltage charging. Gel batteries are best used in VERY DEEP cycle applications and may last a bit longer in hot weather applications. If the wrong battery charger is used on a gel cell battery, poor performance and premature failure will result.

BEFORE USING YOUR CONVERTER

Do not use the converter with a product that draws a higher wattage than the converter can provide, as this may cause damage to the converter and product. When you turn on  a device or a tool that runs on a motor, the device goes through two stages:

1. Start-Up – Requiring an initial surge of power (commonly known as the “starting” or “peak” load).
2. Continuous Operation – Power consumption drops (commonly known as the “continuous load”).

The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most devices and equipment, or in the user’s manual. Otherwise, contact the manufacturer to find out whether the device you want to use is compatible with a modified sine wave.

To calculate the wattage:
Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load:
Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether converter has the capability to power it.
To calculate the continuous load:
Continuous Load = AMPS x 120 (AC Voltage).

IMPORTANT: Always run a test to establish whether the converter will operate a particular piece of equipment or device. In the event of a power overload, the converter is designed to automatically shut down.
This safety feature prevents damaging the converter while testing devices and equipment within the wattage range of the converter.
If a device does not operate properly when first connected to the converter, turn the converter ON/OFF switch ON, OFF, and ON again in quick succession. If this procedure s not successful, it is likely that the converter does not have the required capacity to operate the device in question.
IMPORTANT: This converter uses a nonsinusoidal waveform (Fig. 1) which is not the same as power company electricity (Fig 2). Therefore, we do not recommend you use it to power the following devices:

1. Switch-mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6.  Fan motors
7. Microwave ovens
8. Fluorescent and high-intensity lamps (with a ballast)
9.  Transformer fewer battery chargers

Using the converter with any of these devices may cause the device to run warmer or overheat.

If you are using the converter to operate a rechargeable device,  monitor the temperature of the converter for about 10 minutes. If the converter becomes abnormally hot, disconnect it from the device immediately; do not use the device with the converter.
USING THE CONVERTER TO OPERATE A TV OR AUDIO DEVICE
The converter is shielded and filtered to minimize signal interference. Despite this, some interference may occur with your television picture, especially with weak signals. Below are some suggestions to improve reception.

1.  Try altering the position of the converter, antenna cables, and television power cord. Add an extension cord from the converter to the TV, to isolate its power cord and antenna cables from the 12 volt power source.
2. Try coiling the television power cord and the input cables running from the 12-volt power source to the converter.
3.  Affix one or several “Ferrite Data LineFilters” to the television power cord. Fer- rite Data Line Filters can be purchased at most electronic supply stores.
4. Try grounding the converter with a 16 AWG (minimum) wire, using as short of an extension length as possible.

NOTE: You may hear a “buzzing” sound being emitted from the inexpensive sound systems when operated with the converter. This is due to ineffective filters in the sound system’s power supply. Unfortunately, this problem can only be resolved by purchasing a sound system with a higher quality power supply or higher quality filter.
USING THE USB PORT
The USB port provides up to 2A at 5V DC.

1. Plug the device into the USB port.
2.  Turn the USB device on.
3.  Reverse these steps when finished using the USB port.

WARNING: The converter draws power, even when the switch is OFF. To avoid battery drain, disconnect the converter when not in use.

POWER SOURCE

Your average automobile battery at full charge will provide an ample power supply to the converter when the engine is on. Keep the car running at all times when using the converter. The actual length of time the converter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the converter.
When possible, recharge your batteries when they are not more than 50% discharged. This gives the batteries a  much longer life cycle than recharging when they are ore deeply discharged.  The power converter has a battery low voltage shutdown at 10V±0.5V DC. With moderate to heavy loads, this will protect against over-discharging the battery. If the converter is running only light loads it is advisable to recharge before the converter’s low voltage shutdown point is reached.
IMPORTANT: The converter draws low amperage from the battery with the main ON/OFF switch turned on and no load connected. To prevent battery discharge, turn the converter off when you are not using it.

LED INDICATOR AND SHUTDOWN PROTECTION

The Green LED lights automatically when the converter is plugged into a 12 volt DC power source and is turned on. The Red LED lights, the alarm sounds, and the converter automatically turn itself off  under the following conditions:

1. When the power input from the vehicle’s battery drops to approximately 10.5 volts, the low voltage alarm will sound. When the voltage goes on below 10 VDC, the inverter shuts off. Recharge or replace the battery.
2.  When the power input from the vehicle’s battery exceeds 16 volts, high voltage overload protection occurs.
3. The continuous load demand from the equipment or device being operated exceeds the continuous load rating of the converter. Use a higher capacity converter or lower-rated device.
4. The thermal resistor exceeds 80° C  (176° F.) Allow the converter to cool. Do not block the cooling slots or airflow over and through the converter. Reduce the load on the converter to the continuous rated output.

RESET: To reset after shutdown occurs, switch the converter’s ON/OFF switch to the OFF (O) position. Check the source of the problem and correct it. Switch the converter’s  ON/OFF switch to the ON (I) position.

IF THE CONVERTER’S FUSE BLOWS

Your power converter is fitted with fuses, which should not have to be replaced under normal operating conditions. A blown fuse is usually caused by reverse polarity or a short circuit within the device or equipment being operated.
If a fuse does blow, take the converter to a qualified technician for repair.

MAINTENANCE AND STORAGE INSTRUCTIONS

• Before each use, ensure that all of the converter’s components are in place and in good working condition.
• After use and before performing maintenance, unplug and disconnect the converter.
• Use a clean, dry cloth to wipe the external surfaces of the converter’s case.

BEFORE USING YOUR CONVERTER

• This converter is designed to be used with a single battery, up to group 31 (130 Ah or smaller). The recommended source of power is a 12 volt deep-cycle battery, due to their high reserve capacity.
  Automotive batteries are recommended for only a short period of time of an hour or less.
• Do not use the converter with a product that draws a higher wattage than the converter can provide, as this may cause damage to the converter and product.
  When you turn on a device or a tool that runs on a motor, the device basically goes through two stages:

1. Start Up – Requiring an initial surge of power (commonly known as the “starting” or “peak” load).
2. Continuous Operation – Power consumption drops (commonly known as the “continuous load”).

The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most devices and equipment, or in the user’s manual. Otherwise, contact the manufacturer to find out whether the device you want to use is compatible with a modified sine wave.

To calculate the wattage:
Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load:
Starting Load = 2 x WATTS.

In general, the startup load of the device or power tool determines whether your converter has the capability to power it.

To calculate the continuous load:

Continuous Load = AMPS x 120 (AC Voltage).

IMPORTANT: Always run a test to establish whether the converter will operate a particular piece of equipment or device. In the event of a power overload, the converter is designed to automatically shut down. This safety feature prevents damaging the converter while testing devices and equipment within the wattage range of the converter.
IMPORTANT: When using the vehicle’s 12 volt accessory port, this converter is designed to supply 60 to 70 watts when the vehicle is not running. With the vehicle’s engine running, it can supply up to 100 watts. To use the full output, you must connect the converter directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles.
Some vehicles may allow the full output. If the fuse blows when you switch on the device you are trying to use, you have to either use a smaller device or you must connect the converter directly to the battery.

IMPORTANT: This converter uses a nonsinusoidal waveform, which is not the same as power company electricity. Therefore, we do not recommend you use it to power the following devices:

1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers

Using the converter with any of these devices may cause the device to run warmer or overheat.
If you are using the power converter to operate a battery charger, monitor the temperature of the battery charger for about 10 minutes. If the battery charger becomes abnormally warm, disconnect it from the converter immediately.
NOTE: You can use an extension cord from the converter to the device without significantly decreasing the power being generated by the converter. For best operating results, the extension cord should be no longer than 50 feet.

USING THE USB PORT

The USB port provides up to 2A at 5V DC.

1. Plug the device into the USB port.
2. Turn the USB device on.
3. Reverse these steps when finished using the USB port.
4. Reverse these steps when finished using the USB port.

: The converter draws power, even when the switch is OFF.
To avoid battery drain, disconnect the converter when not in use.

POWER SOURCE

Your average automobile or marine battery at full charge will provide an ample power supply to the converter for approximately 3 hours when the engine is off. The actual length of time the converter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the converter.
If you decide to use the converter while the engine is off, we recommend you turn OFF the device plugged into the converter before starting the engine. To maintain battery power, start the engine every 2 to 3 hours and let it run for approximately 10 minutes to recharge the battery.
Although it is not necessary to disconnect the converter when turning over the engine, it may briefly cease to operate as the battery voltage decreases.
While the converter draws very low amperage when not in use, it should be unplugged to avoid battery drain.

HOW POWER CONVERTERS WORK

There are two stages involved in converting 12 volt DC (battery) power into 120 volt AC (household voltage):
STAGE 1: The power converter uses a DC to DC transformer to increase the 12-volt DC input voltage from the power source to 145 volt DC.
STAGE 2: The converter then converts the 145 volt DC into 120 volts AC (household voltage) using advanced MOSFET transistors in a full bridge configuration. A “modified sine wave” waveform is generated by this conversion.

LED INDICATOR AND SHUTDOWN PROTECTION

The LED glows GREEN when the switch is on, and under the following conditions:

1. When the power input from the vehicle’s battery drops to approximately 10 volts, low battery shutdown occurs and the converter shuts off.
   The Green and Red LEDs are on, with a buzzer. Recharge or replace the battery.
2. When the power input from the vehicle’s battery exceeds 16±0.5 volts, high voltage overload protection occurs. The Green and Red LEDs are on. Reduce the voltage range to between 12 volts and 14 volts.
3. The continuous load demand from the equipment or device being operated exceeds the continuous load rating of the converter being used. The Green LED is on; the Red LED pulses. Use a higher capacity converter or lower-rated device.
4. The case temperature becomes hot (exceeds 145°F). The Green and Red LEDs are on, with a buzzer. Allow the converter to cool. Do not block the cooling slots or air flow over and through the converter. Reduce the load on the converter to the continuous rated output.

TO RESET AFTER SHUTDOWN OCCURS:

1.  Disconnect the converter from the 12V power source.
2. Check the source of the problem and correct.
3. Reconnect the converter to the 12V power source.

NOTE: If the red LED is lit and the green LED is not, see Troubleshooting.

IF A CONVERTER FUSE BLOWS

Your power converter is fitted with two fuses, which should not have to be replaced under normal operating conditions. A blown fuse is usually caused by reverse polarity or a short circuit within the device or equipment being operated.

If a fuse does blow:

1. Disconnect the device or equipment immediately.
2. Find the source of the problem and repair it.
3. Install a new fuse (25A). The fuse can be found on the back of the converter.

IMPORTANT: Do not install a fuse with a higher amp rating than the original fuse, as this may damage the converter and any product you use with the converter. Make sure to correct the cause of the blown fuse before using the converter again.

7. BEFORE USING YOUR CONVERTER

Do not use the converter with a product that draws a higher wattage than the converter can provide, as this may cause damage to the converter and product.
When you turn on a device or a tool that runs on a motor, the device goes through two stages:
1. Start Up ­ Requiring an initial surge of power (commonly known as the “starting” or “peak” load).
2. Continuous Operation ­ Power consumption drops (commonly known as the “continuous load”).

The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most devices and equipment, or in the user’s manual. Otherwise, contact the manufacturer to find out whether the device you want to use is compatible with a modified sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether your converter has the capability to power it.
To calculate the continuous load: Continuous Load = AMPS x 120 (AC Voltage).

Page 7

IMPORTANT: Always run a test to establish whether the converter will operate a particular piece of equipment or device. In the event of a power overload, the converter is designed to automatically shut down.
This safety feature prevents damaging the converter while testing devices and equipment within the wattage range of the converter.
If a device does not operate properly when first connected to the converter, turn the converter ON/OFF switch ON, OFF, and ON again in quick succession. If this procedure is not successful, it is likely that the converter does not have the required capacity to operate the device in question.
IMPORTANT: This converter uses a nonsinusoidal waveform (Fig. 1) which is not the same as power company electricity (Fig 2). Therefore, we do not recommend you use it to power the following devices:
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers

Using the converter with any of these devices may cause the device to run warmer or overheat.

10. BATTERY BANK INSTRUCTIONS

BATTERY BANK ASSEMBLY
READ THESE SAFETY INSTRUCTIONS BEFORE ASSEMBLING THE BATTERY BANK. · Connect batteries ONLY in parallel
(negative terminals together to one cable; positive terminals together to the other cable), as shown in the Battery Bank Example.

· Do not connect 12V batteries in a series with the negative of one battery connected to the positive of the next.
CONNECTING INCORRECTLY MAY RESULT IN VOLTAGE HIGH ENOUGH TO CAUSE ELECTROCUTION.
· While assembling the battery bank, wear splash-resistant ANSI-approved safety goggles and electrically insulated gloves.

Page 9

· Connect Only similar batteries together in a battery bank. Do not connect old to new, flooded to gel cells, or batteries with different capacities.
· Use extension cables with the specified gauge (or thicker).
6′ or less: 4 AWG; 6-10′: 2 AWG
RISK OF EXPLOSIVE GASES.
· Assemble the battery bank in a clean, well-ventilated location, away from ignition sources and flammable materials.
· To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer of any equipment you intend to use in vicinity of a battery. Review cautionary markings on these products.

Page 10

IMPORTANT: Using the converter with some rechargeable devices may damage the converter and/or device. If you are using the converter to operate a rechargeable device, monitor the temperature of the converter for about 10 minutes. If the converter becomes abnormally hot, disconnect it from the device immediately; do not use the device with the converter.
USING THE CONVERTER TO OPERATE A TV OR AUDIO DEVICE
The converter is shielded and filtered to minimize signal interference. Despite this, some interference may occur with your television picture, especially with weak signals. Below are some suggestions to improve reception.
1. Try altering the position of the converter, antenna cables, and television power cord. Add an extension cord from the converter to the TV, to isolate its power cord and antenna cables from the 12 volt power source.
2. Try coiling the television power cord and the input cables running from the 12 volt power source to the converter.
3. Affix one or several “Ferrite Data Line

Filters” to the television power cord. Ferrite Data Line Filters can be purchased at most electronic supply stores.
4. Try grounding the converter with a 16 AWG (minimum) wire, using as short of an extension length as possible.
NOTE: You may hear a “buzzing” sound being emitted from inexpensive sound systems when operated with the converter. This is due to ineffective filters in the sound system’s power supply. Unfortunately, this problem can only be resolved by purchasing a sound system with a higher quality power supply or higher quality filter.
USING THE USB PORTS The USB ports provide up to 2A each at 5V DC.
1. Plug the device into the USB port.
2. Turn the USB device on.
3. Reverse these steps when finished using the USB port.
The converter draws power, even when the switch is OFF. To avoid battery drain, disconnect the converter when not in use.

12. POWER SOURCE
Your average automobile battery at full charge will provide an ample power supply to the converter when the engine is on. Keep the car running at all times when using the converter. The actual length of time the converter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the converter.
When possible, recharge your batteries when they are not more than 50% discharged. This gives the batteries a much longer life cycle than recharging when they are more deeply discharged.

The power converter has a battery low voltage shutdown at 10V±0.5V DC. With moderate to heavy loads, this will protect against over-discharging the battery. If the converter is running only light loads it is advisable to recharge before the converter low voltage shutdown point is reached.
IMPORTANT: The converter draws low amperage from the battery with the main ON/OFF switch turned on and no load connected. To prevent battery discharge, turn the converter off when you are not using it.

Page 11

13. LED INDICATOR AND SHUTDOWN PROTECTION

The Green LED lights automatically when then converter is plugged into a 12 volt DC power source and is turned on. The Red LED lights, the alarm sounds and the converter automatically turns itself off under the following conditions:
1. When the power input from the vehicle’s battery drops to approximately 10.5 volts, the low voltage alarm will sound. When the voltage goes down below 10 VDC, the converter shuts off. Recharge or replace the battery.
2. When the power input from the vehicle’s battery exceeds 16 volts, high voltage overload protection occurs.

3. The continuous load demand from the equipment or device being operated exceeds the continuous load rating of the converter. Use a higher capacity converter or lower rated device.
4. The thermal resistor exceeds 80° C (176° F.) Allow the converter to cool. Do not block the cooling slots or air flow over and through the converter. Reduce the load on the converter to the continuous rated output.
RESET: To reset after shutdown occurs, switch the converter’s ON/OFF switch to the OFF (O) position. Check the source of the problem and correct. Switch the converter’s ON/OFF switch to the ON (I) position.

14. IF THE CONVERTER’S FUSE BLOWS

Your power converter is fitted with fuses, which should not have to be replaced under normal operating conditions. A blown fuse is usually caused by reverse polarity or a short circuit within the device or equipment being operated.

If a fuse does blow, take the converter to a qualified technician for repair.

15. MAINTENANCE AND STORAGE INSTRUCTIONS
