This power inverter can be used on 12 V Vehicles or 24 V Trucks, Boats, RVS.
When rstly connected to a battery, the inverter will indentify battery’s voltage and record it,
then it will perform under this voltage. For example, once it connect to Truck’s battery-24 V,
it will perform as low-voltage shutdown at 20–22 V and high-voltage shutdown at 30–32.6 V.
If change to different voltage of battery, you need to power off the inverter rstly, Connect to
a new battery with different voltage (for example 12 V), then power on the inverter, it will
indentify the voltage of new battery.
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 use the power inverter in a truck in which the plus pole of the car battery is
connected to the chassisl Before using the device, please determine how the battery is
connected in the respective vehicle.
• Do not operate the power inverter if it has been dropped or damaged in any way.

SAFETY INFORMATION

CAUTION!
CAUTION!
• DO NOT USE the power inverter with the following equipment:
• Do not insert foreign objects into the power inverter or ventilation openings.r
• 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 truck'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).
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.
• REVERSE POLARITY Power connections from a 12 V or 24 V battery to the power inverter
must be positive to positive and negative to negative. A reverse polarity connection
(positive to negative) will blow a fuse in the power inverter and might need to replace a
new fuse. Damage caused by a reverse polarity connection is not covered by your
warranty.
• Disconnect the power cable whenever the engine is switched off for extended periods of
time In some trucks, the power does not turn off after the engine has been switched off.
If the plug is left connected, the truck battery might become discharged or damaged.
• Using the device for extended periods of time can completely discharge the truck 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 truck in a closed garage, as the carbon monoxide in the
exhaust is fatal.
• It is better to work 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
truck.

KEY PARTS DIAGRAM KEY PARTS DIAGRAM

The power inverter is an electronic device that converts the low-voltage 12 V or 24
V(direct current) from a battery, as can be found in trucks, or other similar power
sources, to the conventional 115 V (alternating current) like you have in your home. Do
not connect this power inverter to batteries below 12 V.
This conversion process thereby allows you to run standard household devices in all
cars including 12 V Vehicles and 24 V Trucks, Boats, RVs anywhere else.
This power inverter uses a modied sine wave that delivers power consistent and
efcient enough to run most devices adequately.
Determining the maximum load of connected devices
WARNING!
IMPORTANT!
VOLTS x AMPERE = WATTS
Formula: 120 Volts x XAmperes = XXXX Watts
Example: 120 Volts x 2Amperes = 240 Watts
CAUTION!
Understand the difference between rated (running) wattage and surge (starting)
wattage.
The RATED (RUNNING) WATTAGE is the average amount of power that a device consumes
continuously.
DO NOT overload your power inverter! Overloading the power inverter, even for a short
time, could result in serious damage to the power inverter and/or to the connected
device.
A few simple steps are necessary to avoid overloading the power inverter:
• Identify all devices that you would like to power.
• Add up the total wattage of devices that will be powered. The wattage can be found on
the individual device’s rating plate, as well as in the instruction manual.
In some cases, the wattage might not be listed on the devices you want to connect to the
power inverter. In that case, calculate the wattage using the following equation:

OPERATION INTENDED USE

The SURGE (STARTING) WATTAGE is the amount of power that a device consumes at start-
up for a limited period of time (2–3 seconds). Some devices (e.g. induction motors of drills
and fans) may have a start-up surge of 3 to 7 times the rated wattage.
IMPORTANT!
POWER RATING MAXIMUM WATTAGE
Continuous power rating (RATED WATTAGE) 400 W
Surge rating max. (SURGE WATTAGE) 800 W
Wattage of commonly used devices
IMPORTANT!
The wattages given on next page are estimates. The actual wattage required for your devices
may differ from those listed. Be sure to chec wattage requirements on the rating
label and in the operating instructions of devices to be used.
The power inverter can supply momentary surge power that is higher (800 W) than its
maximum power rating (400 W). Some products with a rated wattage lower than the
maximum power rating for your power inverter may still exceed the power inverter's surge
capability and trigger an overload shutdown.
Products rated with the following power and surge ratings or less can be connected to the
power inverter.
NOTE: Power requirements for product examples are estimates only. To calculate the wattage
of a product, use the following equation: amperage x 115.
