• DO NOT use with positive ground electrical systems.* Reverse polarity connection will result in a blown fuse and
may cause permanent damage to the inverter and will void warranty.
*The majority of modern automobiles, RVs and trucks are negative ground.
• Keep in mind that this inverter will not operate high wattage appliances or equipment that produce heat, such as
hair dryers, microwave ovens and toasters.
• Do not open the inverter — there are no user-serviceable parts inside. Opening the inverter will void
manufacturer’s warranty.
• Do not use this inverter with medical devices. It is not tested for medical applications.
• Install and operate unit only as described in this Instruction Manual.
• Check inverter periodically for wear and tear. Return to manufacturer for replacement of worn or defective parts
immediately.

RISK OF UNSAFE OPERATION.
When using tools or equipment, basic safety precautions should always be
followed to reduce the risk of personal injury. Improper operation, maintenance or modification of tools or equipment
could result in serious injury and property damage. There are certain applications for which tools and equipment
are designed. Manufacturer strongly recommends that this product NOT be modified and/or used for any application
other than for which it was designed.
READ ALL INSTRUCTIONS
WARNING:
Read all instructions before operating your inverter. Failure to follow all instructions may result in
electric shock, fire and/or serious injury.
• AVOID DANGEROUS ENVIRONMENTS.
Don’t use inverters in damp or wet locations.
• KEEP CHILDREN AWAY.
Keep away from children. This is not a toy!
• STORE INDOORS.
When not in use, inverters should be stored indoors in dry, and high or locked-up places –
out of reach of children.
• DON’T ABUSE CORD.
Never carry inverter by cord or yank the cord to disconnect from receptacle. Keep cord
from heat, oil, and sharp edges.
• DISCONNECT INVERTER.
Disconnect the inverter from the power supply when not in use.
• PROPER COOLING
is essential when operating the inverter. Do not place it near a vehicle’s heat vent or in direct
sunlight.
• USE OF ACCESSORIES AND ATTACHMENTS.
The use of any accessory or attachment not recommended by
manufacturer for use with this inverter could be hazardous.
• STAY ALERT.
Use common sense. Do not operate inverter when you are tired.
• CHECK FOR DAMAGED PARTS.
Any part that is damaged should be properly repaired or replaced by an
authorized service center unless otherwise indicated elsewhere in this instruction manual before further use. Do
not use inverter if switch does not turn it on and off.
• DO NOT OPERATE
inverter near flammable liquids or in gaseous or explosive atmospheres. Motors in tools or
appliances used with the inverter may spark, and the sparks might ignite fumes.
IMPORTANT SAFETY INSTRUCTIONS
WARNING:
This product or its power cord may contain lead, a chemical known to the State of California to
cause cancer and birth defect or other reproductive harm. Wash hands after handling.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK:
• DO NOT connect to AC distribution wiring.
• DO NOT make any electrical connections or disconnections in areas designated as IGNITION PROTECTED. This
inverter is NOT approved for ignition protected areas.
• NEVER immerse the inverter in water or any other liquid, or use when wet.
• DO NOT insert foreign objects into the inverter’s outlets.
WARNING: TO REDUCE THE RISK OF FIRE:
• Do not operate near flammable materials, fumes or gases.
• DO NOT expose to extreme heat or flames.
CAUTION: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• Remove appliance plug from outlet before working on the appliance.
• DO NOT attempt to connect or set up the inverter or its components while operating your vehicle. Not paying
attention to the road may result in a serious accident.
• ALWAYS use the inverter where there is adequate ventilation. Do not block ventilation slots.
• ALWAYS turn the inverter off by disconnecting it from the power source when not in use.
• The inverter MUST be connected only to batteries with a nominal output voltage of 12 volts. The unit will not
operate from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
• When using this unit in a vehicle, check the vehicle owner’s manual for maximum power rating and recommended
output. DO NOT install in engine compartment — install in a well ventilated area.
