IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS1.1 SAVE THESE INSTRUCTIONS. This manual will show you how to use your inverter safely and effectively. Please read, understand and follow these instructions and precautions carefully, as this manual contains important safety and operating instructions.WARNING: The inverter output is 120V AC and can shock or electrocute the same as any ordinary household AC wall outlet.1.2 Keep out of reach of children.1.3 For the most effective use, place the power inverter on a flat surface.1.4 Keep the inverter well ventilated in order to properly disperse heat generated while it is used. Make sure there are several inches of clearance around the top and sides and do not block the slots of the inverter.1.5 Make sure the inverter is not close to any potential source of flammable fumes or clothing.1.6 Do not place the inverter in areas such as battery compartments or engine compartments where fumes or gases may accumulate.1.7 Keep the inverter dry. DO NOT allow the inverter to come into contact with rain or moisture.1.8 DO NOT operate the inverter if you, the inverter, the device being operated or any other surfaces that may come into contact with any power source are wet. Water and many other liquids can conduct electricity, which may lead to serious injury or death.1.9 Do not place the inverter on or near heating vents, radiators, or other sources of heat or flammable materials.1.10 Do not place the inverter in direct sunlight. The ideal air temperature for operation is between 50° and 80°F.1.11 Only connect the power inverter to a 12-volt battery or power supply. Do not attempt to connect the inverter to any other power source, including an AC power source.Connecting to a 6 volt or 16-volt battery will cause damage to the inverter.1.12 Make sure the AC plug is tight.1.13 Do not modify the AC receptacle in any way.1.14 Do not try extending or otherwise changing the 12-volt power cord supplied with your inverter. Make sure the cord connections are tight.1.15 Incorrect operation of your inverter may result in damage and personal injury.1.16 Do not use the inverter with a product that draws a higher wattage than the inverter can provide, as this may cause damage to the inverter and product.1.17 Do not open – No user-serviceable parts inside.1.18 This device does not include an internal Ground Fault Circuit Interrupter (GFCI).1.19 Restrictions on Use: This inverter may not be used in life support devices or systems. Failure of this inverter can reasonably be expected to cause failure of that life support device or system, or to affect the safety or effectiveness of that device or system.

BEFORE USING YOUR POWER INVERTER

NOTE: This inverter is designed to be used with a single battery, up to group 31 type (130 Ah or smaller in size).NOTE: Do not use the inverter with a product that draws a higher wattage than the inverter can provide, as this may cause damage to the inverter 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 start-up load of the device or power tool determines whether your inverter 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 inverter will operate a particular piece of equipment or device. In the event of a power overload, the inverter is designed to automatically shut down. This safety feature prevents damaging the inverter while testing devices and equipment within the wattage range of the inverter.If a device does not operate properly when first connected to the inverter, turn the inverter ON (I), OFF (O), and ON (I) again in quick succession. If this procedure isnot successful, it is likely that the inverter does not have the required capacity to operate the device in question.IMPORTANT: This inverter is designed to power 100-watt devices or less when used with the vehicle 12-volt accessory port. To use the full output you must use the battery clips adapter and connect the inverter directly to the battery.NOTE: The 100-watt limit is to accommodate the fuse ratings for all vehicles.Some vehicles may allow 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 purchase the 12-volt accessory outlet to battery clips adapter (Schumacher Model SAC-103) and connect the inverter directly to the battery.IMPORTANT: This inverter uses a nonsinusoidal waveform. 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. Transformerless battery chargers

Doing so may cause the device to run warmer or overheat.

OPERATING INSTRUCTIONS

1. Push the 12-volt power plug firmly into the 12V accessory outlet.
2. The LED indicator light should glow GREEN, verifying the inverter is receiving power.
3. Make sure the device to be operated is turned OFF.
4. Plug the device into the inverter AC outlet or USB port.
5. Turn the device on.
6. To disconnect, reverse the above procedure.

NOTE: You may hear a “buzzing” sound being emitted from inexpensive sound systems when operated with the inverter. 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.

POWER SOURCE

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

LED INDICATOR AND SHUTDOWN PROTECTION

The LED glows GREEN automatically when plugged into a 12 volt DC source and will not glow under the following conditions:

1. When the power input from the vehicle’s battery drops to approximately 10V, low battery shutdown occurs and the inverter shuts off. Solution: Recharge or replace the battery.
2. When the power input from the vehicle’s battery exceeds 15V, high voltage protection occurs. Solution: Reduce the voltage range to between 12V and 14V.
3. The continuous load demand from the equipment or device being operated exceeds the continuous load rating of the inverter being used. Solution: Use a higher capacity inverter or lower-rated device.
4. The case temperature becomes hot (exceeds 145°F). Solution: Allow the inverter to cool. Do not block the cooling slots or air flow over and through the inverter. Reduce the load on the inverter to the continuous rated output.

RESET: To reset after shutdown occurs, remove the 12-volt plug from the accessory outlet. Check the source of the problem and correct it. Reinsert the 12V plug into the accessory outlet.

IF THE INVERTER FUSE BLOWS

Your power inverter is fitted with a fuse, 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 the 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 (15A). The fuse can be found on the end of the plug on the inverter.
4. Do not tighten the fuse cap too tight; finger-tight is sufficient.

ATTENTION: Do not install a fuse higher than 15A, as this may damage the inverter.Make sure to correct the cause of the blown fuse before using the inverter again.
