STEP 3
Connect the correct connector cable to the
power inverter. Make sure to connect the RED
CABLE TO THE POSITIVE PORT (+) and the
BLACK CABLE TO THE NEGATIVE PORT (
- ).
Insert the connectors into the correct
cabling terminals until fully inserted. Turn
the connectors until the security latches
snap into the locking position.
STEP 1
Calculate the wattage of the AC devices that
you want to connect to the power inverter.
STEP 2
Decide which DC power source you will
connect the power inverter to.

This manual contains information that relates to PROTECTING PERSONAL SAFETY and
PREVENTING EQUIPMENT PROBLEMS. It is very important to read this manual carefully and
understand it thoroughly before using the product. The symbols listed below are used to
indicate this information.
DANGER!
Potential hazard that will result in serious injury or loss of life.
WARNING!
Potential hazard that could result in serious injury or loss of life.
CAUTION!
Potential hazard that may result in moderate injury or damage to equipment.
IMPORTANT!
Installation, operation, or maintenance information that is important but not hazard related.
WARNING!
• HEATED SURFACE. The power inverter housing may become uncomfortably warm,
and can reach up to 60°C (140°F) under extended high power operation.
• Do not operate the power inverter if it has been dropped or damaged in any way.
• Always disconnect the device by pulling on the plug itself, not the power cable.
• The device must be fastened so that it does not cause a safety hazard in case of collision
or hard braking.
• Route the power cable so that it does not interfere with the driver of the vehicle when
plugged into the vehicle's 12 V outlet.
• Prevent the power supply cable from hanging over sharp edges.
• Using improper voltage may result in damage to the device and possible injury to the
user. The correct voltage is listed on the rating plate.
• Never leave the device unattended during operation.
CAUTION!
• Do not connect live AC power to the power inverter’s AC outlets. The power inverter will
be damaged even if it is switched off.
• Avoid placing the power inverter on or near heating vents, radiators or other sources
of heat. Do not place the power inverter in direct sunlight (e.g. on the vehicle's dashboard)
in order to prevent an overheat shutdown caused by high temperatures. Do not use the
power inverter in temperatures over 40°C (104°F).
• Do not insert foreign objects into the power inverter's outlets or ventilation openings.

SAFETY INFORMATION
SAFETY INFORMATION

CAUTION!
• DO NOT USE the power inverter with the following equipment:
Small battery-operated devices such as rechargeable ashlights,
some rechargeable shavers, and night lights that are plugged
directly into an AC receptacle to recharge. The device can be
damaged if connected to the power inverter. Always
recharge batteries using a separate battery charger.
Battery chargers used in power tools. These chargers display a
WARNING LABEL stating that there are dangerous voltages at the
charger’s battery terminals.
• Disconnect the power cable whenever the engine is switched off for extended periods of
time. In some vehicles, thepower doesnot turn off after the engine has been switched off.
If the plug is left connected, the vehicle battery might become discharged or damaged.
• Using the device for extended periods of time can completely discharge the vehicle
battery.
• When using a power inverter continuously inside a vehicle that is not running, the
engine should be started at least once an hour for 10
- 15 minutes to keep the battery
from discharging. Do not start a vehicle in a closed garage, as the carbon monoxide in the
exhaust is fatal.
• Power inverters work best with a battery that is in good condition and fully charged.
A weak battery will be drained easily if demands are too high. This could leave you
stranded so be sure to check the battery’s condition before using a power inverter in
a stationary vehicle.
