Part # 53040
DC to AC 400 Watt Power Inverter
Instruction Manual
CAUTION: SERIOUS SHOCK HAZARD. This inverter should only be
serviced by qualified personnel.
This 400 watts power inverter converts 12-volt vehicle battery power into 110 volts of AC
power. You can use this inverter in your vehicle to operate many types of appliances that
use AC power such as TVs, VCRs, portable computers, power tools and lights for
emergency use or camping use.
This inverter works with your vehicle’s engine turned on or off (accessory mode). It
provides a continuous output of up to 400 watts.
Power
To determine the amount of load that an electrical appliance will place on the inverter use
the following equation: Watts =Amps X Volts
Example: An appliance consumes 2.5 Amps of power to operate, how many watts will it
take to power it? Watts = Amps X Volts
Watts = 2.5 Amps X 110 Volts
Watts = 275
This appliance would consume 275 watts from the inverter.
BASIC OPERATION
CAUTION: Use the right operating voltage for both input and output of the inverter.
Make sure inverter is switched off before connecting or disconnecting the inverter
to or from the battery.
Powering devices with power rating:
Less than 150 Watts by connecting the cigarette lighter plug into the vehicle’s
cigarette lighter socket.
RED+
BLACK-

More than 150 Watts by connecting RED terminal from inverter to + of battery
terminal and connect BLACK terminal from inverter to –of battery terminal. NOTE:
There will be a spark between the cable from the negative terminal of the inverter
when it is first connected to the negative terminal of the battery.
Insert the plug of your appliances intoAC socket at the front of the inverter.
Turn ON the power switch that is located at the front of the inverter, and the green
LED light will light as indicator that the is working.
CAUTION:
DO NOT USE THE INVERTER IN A POSITIVELY GROUNDED VEHICLE.
DO NOT POWER MORE THAN 150 WATTS WHEN THE POWER INVERTER IS
CONNECTED TO THE CAR CIGARETTE LIGHTER SOCKET POWER SUPPLY.
DOING SO MIGHT DAMAGE YOUR VEHICLE’S FUSE OR ELECTRICAL SYSTEM.
RECOMMENDATION
If the power inverter makes a beeping sound, turn OFF the power inverter and
disconnect all appliances from the inverter and disconnect the inverter from the
power supply. The beeping sound is the low battery warning, which indicates that the
voltage of the battery power supply is too low to operate the inverter. Start the vehicle
engine and let the battery charge before reconnecting and operating the power
inverter.
When the inverter is not in use, turn the switch to the OFF position and disconnect the
inverter from the power supply.
Disconnect the inverter before starting the vehicle’s engine.
BATTERY USE
To avoid over-discharging your vehicle’s battery, disconnect the inverter from the
battery, start and run the vehicle to maintain the battery voltage, reconnect the
inverter to the battery.
If you choose to connect the inverter directly to your battery terminals, it is important
to connect correctly with the right polarity. Connect the positive (+) RED cable from
RED terminal on the inverter to the positive (+) battery terminal and connect the
negative (–) BLACK cable from the BLACK terminal on the inverter to the negative (–)
battery terminal.

CAUTION:
THE FOLLOWINGS OPERATION WILL DAMAGE THE UNIT:
CONNECTING THE WIRES TO THE INCORRECT TERMINALS CAUSES
REVERSE POLARITY（Fuse will blow and user will need to replace the fuse）
CONNECTING THE BATTERY CHARGER TO THE BATTERY WITHOUT FIRST
DISCONNECTING THE INVERTER.
OPERATING THE INVERTER AND BATTERY IN OR AROUND WATER.
MEASURING THE AC VOLTAGE
The output waveform of the AC output is a MODIFIED SINE WAVE. To measure the AC
output voltage, you must have a TRUE RMS VOLTMETER.
SAFETY PRECAUTION
Do not open the case of the inverter. The high voltage inside the unit is the same
type of power as our electrical outlets at home. Opening the case can cause
electrical shock which can cause severe injury or death.
Do not let the cord of the inverter or any appliance’s cord get wet.
Do not operate the inverter in or around water. The voltage of the unit makes
electrical shock hazard if operated in wet conditions which can cause severe
injury or death.
Do not connect theAC inverter directly to anotherAC power source.
Keep it away from children, this inverter produces 110 AC power which is the
same as AC wall outlets and should be used with extreme caution.
Allow at least 2 inches of clearance around the inverter for airflow.
If you operate the inverter in a moving vehicle, you need to secure the inverter to
prevent it from shifting while the vehicle is moving.
If there is any problem with the inverter, turn the switch off and disconnect it from
the battery.

TROUBLE SHOOTING
TROUBLE/INDICATION
POSSIBLE CAUSE
SUGGESTED REMEDY
-No AC output: - the Green
LED light is not on
-DC input below 10
Volts(12-volt input)
-Recharge or replace battery
-No AC output --inverter is
cold
-Poor connection with the
battery.
-Disconnect load from inverter.
Reconnect the unit to the cigarette
socket.
-Shut down after operating
for a long time
-Over-temperature
-Low Battery Charge
-Disconnect the inverter and put aside
for while to let inverter cool.
-Charge battery.
-Shut down after operating
a short time and inverter is
cold
-Over-Load
-Reduce the wattage of the inverter’s
load
DESCRIPTIONS:
400W Continuous Power: - Inverter can be used to power appliances that require up to
400 watts of power to operate.
800W Peak Power: - Inverter can be used to power appliances that require more power
during start up, up to 800 watts, but only up to 400 watts of power to operate. (such as
TVs and motor-power equipments).
Low Battery Alarm: - The inverter sounds an audible alarm and then turns itself off if the
source battery voltage becomes too low.
Auto shutdown/reset protection: - If the inverter becomes overheated it temporarily
shuts itself down to protect itself from overheating.
Overload/Short Circuit Protection: - The inverter automatically turns itself off if the
connected load is too high or if it shorts.
AC Outlet: - Allows you to plug in an appliance for AC power.
Fan: - Helps remove heat from the inverter. The sound of the fan running a air moving
through the inverter is normal.
HEAT DISPERSAL
The inverter generates heat while it is working. This is normal. However, if the inverter
gets too hot while working, it will turn off by itself.
Position the inverter where air flows freely around it to allow the heat to disperse.
The inverter’s thermal protection prevents it from operating when its temperature exceeds
140+/-9 °F (60+/-5°C). Noise from the fan operating to cool the inverter is normal.
