SECURITY WARNINGS
The voltage inverter INV-300 will give you an output voltage of 300W
AC, furthermore, INV-400, INV-600 and INV-1000 will give you 300, 600
and 1000W of power output. Connect into the voltage inverter’s outputs
the same kind of equipment you would to a home energy output.
The voltage inverter will heat up when in use, avoid touching the
inverter or placing the inverter near objects that can not be near extreme
heat including sleeping bags or anything ammable.
Make sure that the DC voltage input is the same voltage as that
required by the voltage inverter and that the charge is the same as
required by the voltage inverter’s output.
Make sure the polarity is not inverted when connecting your inverter.

GENERAL PRECAUTIONS WITH BATTERIES
1.- It is dangerous to operate near a lead acid battery. The batteries
can generate ammable gases during their operation. Never smoke or
allow it to produce a spark or ame near a battery. Allow adequate
ventilation around the battery.
2.- Wear protective clothing and safety glasses for the eyes. Avoid
touching your eyes working near the battery. Wash your hands once
you’re done.
3.- If the battery acid comes into contact with skin or clothing, wash
the affected area immediately with soap and water. If the acid comes
into contact with eyes, wash immediately with cold water for at least 15
minutes and seek medical attention.
4.- Take caution when using metal tools near the battery. If a metal tool
falls on the battery may cause short-circuit the battery and possibly an
explosion.
5.- Remove any metal object personnel, including rings, bracelets,
necklaces or watches, when working with a battery. A battery can
produce a short circuit in the ow strong enough to melt a ring or other
object similar to the metal, causing acute burned.

Even in OFF position, the inverter consumes a low level of power
from the battery.
Make sure do not overload the maximum inverter voltage capacity
(300, 400, 600, 1000W, depending of the model).
Pay attention to polarity when plug the alligators to the battery.
Red terminal is positive (+) and black terminal is negative (-)

INSTALLATION
a) Selecting the battery power source
You must use a power source with a minimum voltage of 10,5V and a
maximum voltage of 14,5V DC, in order to connect it to the inverter.
The power source can be a combination of car’s battery and alternator
(when the car’s motor is running).
Do not install the power inverter in a positive ground DC system.
The power inverter must be connected to batteries or power
sources with a normal / average voltage of 12V. The power inverter
won’t operates with 6V or 24V power sources.
b) Placing the power inverter
The place where you want to install the inverter is very important, in
order to maximize their use and extend the life of the inverter. For better
results, the inverter must be placed in a sturdy, at surface. You can
place the equipment in a vertical or horizontal position.

ENGLISH
ENGLISH-09
Keep in mind these points when you select a permanent place for
the inverter:
1.- Ventilation: make sure to have at least 1 inch of clearance around
the inverter, for a better air ow. Do not place objects over the
inverter while is in use. The air should circulate freely. The built-
in fan provides air, but must have enough free space around it to
operate correctly.
2.- Keep the equipment dry and far from liquids. Place it far away
spill areas.
3.- Best operating temperature is from 7° to 30°C. Do not place
the inverter in a place near to heat tubes or any other heat sourc-
es, that can overheat the inverter.
4.- Do not place the inverter near to ammable substances.
Fumes and gas may cause an explosion or re that can result in
several damages and possible death.
c) Connection cables from inverter to battery
The power inverter includes 2 4AWG cables (45cm length) with
eye-type and alligator ends to connect it the inverter to a battery.
You can identify the negative end with a black color and the
positive end with a red color. Please, place the inverter as close as
possible to the battery, in order to get the best performance.

ENGLISH
ENGLISH-10
d) Grounding the inverter
Do not install the inverter in a positive ground DC system.
To identify a positive ground DC system, look for the positive terminal of
the battery connected to the chassis or to a central grounding point.
e) Connecting to a power source
Usually, the power source is a battery (or group of batteries) which is
recharged by an alternator.
1.- Make sure the inverter’s power switch is on OFF position and there
are no liquids near of it.
2.- Connect the eye-type terminals (supplied with the inverter). Place
the black cable in the middle of the negative connector (-), and place the
red cable in the positive connector (+).
3.- Tighten the screws rmly to hold the cables.
4.- Use the red alligator to connect it to positive end (+) in the power
source.
5.- Use the black alligator to connect the inverter to power source’s
negative end (-).
6.- Turn the inverter on. The indicator light and the surge
indicator will light up.
7.- Turn the inverter. The installation nished.
If the polarity is inverted, may cause several and permanent
damages in the inverter.
You will watch some sparks when connect the battery to the
inverter. Make sure there are not ammable liquids near the
inverter, may cause an explosion.

HOW TO USE THE INVERTER
1.- Plug the power cord from the electric device that you want to use
with the inverter, into one of the outlets. Make sure the device is power
off before to connect it in the inverter.
2.- Turn the inverter on.
3.- Turn the electric device on. If you plugged two devices into the
inverter, make sure to turn them on separately, this will insure that the
power inverter does not have power peaks at the
moment to turn the device on, at the same time.
If you plugged two devices to the inverter, make sure the sum of
the voltages do not exceeds the maximum capacity of the inverter
(400, 600, 1000W depending of the model)
BATTERY OPERATION TIME
The battery operation time is dependant on the battery capacity (Ah)
and the charge potency (W).
The method to calculate the operation time is:
Battery capacity (Ah) x input voltage / charge potency (W)
Example:
Battery capacity = 80Ah
Input voltage = 12 V - - -
Charge potency = 200 W
(80Ah x 12 V ) / 200 W = 4.8 h

PROTECTION CHARACTERISTICS
Low voltage protection
The inverter will automatically turn off when the DC voltage is
below the required amount. The input voltage range is 11 – 14 volts.
When the DC voltage is below 11 volts, the buzzer will sound. When the
DC voltage is below 10 volts, the inverter will automatically turn off.
High voltage protection
The inverter will automatically turn off when the DC voltage is
above the required amount. The input voltage range is 11 – 14 volts.
When the DC voltage is above 14 volts, the inverter will automatically
turn off.
Overcharge protection
The inverter will automatically turn off when the input charge is higher
than the required amount.
Short-circuit protection
The inverter will automatically turn off when a short-circuit
occurs.

ENGLISH
ENGLISH-13
Temperature protection
The temperature will become too high for the inverter when it is in
use for an extended period of time or when it is not well ventilated.
The inverter will automatically turn off when the temperature reaches
65°C. If you need to use the inverter for an extended period of time, the
charge needs to be 80% of the average. Also, make sure the inverter is
well ventilated.
Restore button
You must press this button, after the protection systems is
activated. When you press it, the system will back to initial mode, then
you can continue using the inverter in a normal way.
