Important Safety Instructions
Page 3 of 12
1. This manual contains important safety and operating instructions for power inverter.
This manual will show you how to use your inverter safely and effectively.
Please read, understand and follow these instructions and precautions carefully.
2. Keep out of reach of children.
3. Do not expose inverter to rain or snow.
4. Use of an attachment not recommended or sold by the unit manufacturer may result in
a risk of fire, electric shock, or injury to persons.
5. Do not disassemble the unit; take it to a qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk of electric shock or fire.
6. To reduce risk of electric shock, unplug unit from outlet before attempting any mainte
nance or cleaning. Turning off controls will not reduce this risk.
7. For the most effective use, place the power inverter on a flat surface.
8. Do not place the inverter on or near heating vents, radiators or other sources of heat of
flammable materials.
9. Do not place the inverter in direct sunlight. The ideal air temperature for operation is
between 41° and 95°F.
10. Only connect the power inverter to a 12V battery or power supply. Do not attempt
to connect the inverter to any other power source, including an AC power source.
Connecting to a 6V or 16V battery will cause damage to the inverter.
11. 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.

Intended Use
Page 4 of 12
Power Inverters convert DC electricity to AC electricity then offer power to small electrical
equipment and digital products. It has been widely used in cars, steamboats, mobile
office, post and telecommunications, public security and emergency.
Electrical equipment can be used:
1. Office equipments: Compute, printer, facsimile printer, min-duplicator,
projector, working light.
2. Digital products: Most of mobile phone / digital camera / digital projector, PDA, palm
computer, recreational machines.
3. Small house electrical equipment: TV, fan, water dispense, dust collector, small electric
iron, hair drier.
4. Hardware appliance: Portable electric drill, waxing machine, electric iron.
Electrical equipment can not be used:
1, All electric appliances that exceed the rated power of the inverter
2, Generally capacitive load and perceptual load appliances are inapplicability: Air
condition, high power electric drill, fridge, microwave oven, blender.
3, Not recommend appliances which have strict requirements on power supply, such as
precise equipments, if use ordinary power inverters with this kind of equipment will
affect the measuring data.
USB charger
Some appliances must charge with original charger, Please read appliance’s manual
before use.

To Ground the Inverter
Make sure to connect your inverter only to a 12 volt power supply. To avoid electrical
shock, it is necessary to ground the inverter as well as the device powering it. The inverter
should be grounded
NOTE: Do not turn on the inverter or the power source until the inverter and the power
source are grounded.
Vehicle: Connect to the chassis, unpainted frame part, or engine block of the vehicle.
Fixed location: Connect to a ground rod or other appropriately rated ground.
Power Source
Your average automobile battery at full charge will provide an ample power supply to
the inverter when the engine is on.
Keep the car running at all times when using the inverter. The actual 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.
When possible, recharge your batteries when they are not more than 50% discharged.
This gives the batteries a much longer life cycle than recharging when they are more
deeply discharged.
The power inverter has a battery low voltage shutdown at 9.2-9.8VDC. With moderate
to heavy loads, this will protect against over-discharging the battery. If the inverter is
running only light loads it is advisable to recharge before the inverter low voltage
shutdown point is reached.
IMPORTANT: The inverter draws low amperage from the battery with the main ON/OFF
switch turned on and no load connected. To prevent battery discharge, turn the inverter off
when you are not using it.

Operating instruction

Connecting inverter to 12V battery / vehicle
1. Locate the Positive and Negative terminals on the inverter
2. From the POSITIVE (RED) and the NEGATIVE (BLACK) terminals, loose the screws,
3. Place the cable’s POSITIVE (RED) bare end into the POSITIVE (RED) inverter
terminal. Place the NEGATIVE (BLACK) bare end into the NEGATIVE (BLACK) inverter
terminal.
4. Tighten both terminal screws.
5. Switch the inverter to OFF (O) position. Connect battery clamp to 12V battery, positive
to positive, negative to negative.
or use the 12V DC car plug connecting to the 12V outlet on vehicle.

Note
If more than one device is to be powered, start one device at a time, to avoid a power
surge and overloading the inverter. The surge load of each device should not exceed
the inverter’s Continuous Operation wattage rate.
Load devices should not exceed 150 W when using in the vehicle.
Using the inverter with some rechargeable devices may damage the inverter and/or
device. If you are using the inverter to operate a rechargeable device, monitor the
temperature of the inverter for about10 minutes. If the inverter becomes abnormally
hot, disconnect it from the device immediately; do not use the device with the inverter.
Please use the inverter in ventilate condition and make sure the fan is not blocked.
To save energy, the fan will not work unless the following two situations:
1.Load is exceed 30% of the related power of the inverter.
2.Temperature of the inverter exceed 60ºC.
Operating
1. Connect the inverter to power source (see inverter connecting section).
2. Switch the inverter’s ON/OFF switch to the ON (I) position.
3. The GREEN LED indicator will light, indicating the inverter is receiving power.
4. Switch the inverter’s ON/OFF switch to the OFF (O) position.
5. Make sure the device to be operated is turned OFF.
6. Plug the device into the inverter’s AC outlet.
7. Switch the inverter’s ON/OFF switch to the ON (I) position.
8. Turn the device on.
9. To disconnect, reverse the above procedure.

Fuse blows
Page 9 of 12
Your power inverter is fitted with fuses, 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 a fuse does blow, take the inverter to a
qualified technician for repair.
