SAVE THESE INSTRUCTIONS.
This manual contains important safety and operating instructions.
RISK OF ELECTRIC SHOCK OR FIRE.
Keep out of reach of children.1.1
Keep the inverter well ventilated in order 1.2
to properly disperse heat generated while it
is in use. Make sure there are several inches
of clearance around the top and sides and do
not block the slots of the inverter.
• 2 •
Make sure the inverter is not close to any potential source of 1.3
ammable fumes or clothing.
Do not place the inverter in areas such as battery compartments 1.4
or engine compartments where fumes may accumulate.
Keep the inverter dry.1.5
DO NOT allow the inverter to come into contact with rain or moisture.1.6
DO NOT operate the inverter if you, the inverter, the device being 1.7
operated or any other surfaces that may come into contact with
any power source are wet. Water and many other liquids can
conduct electricity, which may lead to serious injury or death.
Do not place the inverter on or near heating vents, radiators or 1.8
other sources of heat or ammable materials.
Do not place the inverter in direct sunlight. The ideal air 1.9
temperature for operation is between 50° and 80°F.
Only connect the power inverter to a 12-volt accessory outlet. Do 1.10
not attempt to connect the inverter to any other power source,
including an AC power source. Connecting to a 6-volt or 16-volt
battery will cause damage to the inverter.
Make sure the AC plug connection is tight.1.11
Do not modify the inverter in any way including cables, plugs or 1.12
switches as it may result in property damage or personal injury.
1.13 Incorrect operation of your inverter may result in
damage and personal injury. The inverter output is 120V AC and
can shock or electrocute the same as any ordinary household AC
wall outlet.
Do not open – no user serviceable parts inside.1.14
This device does not include an internal Ground Fault Circuit 1.15
Interrupter (GFCI).
BEFORE USING YOUR POWER INVERTER2.
NOTE: This inverter is designed to be used with a single battery,
up to group 31 (130 Ah or smaller). The recommended source of
power is a 12 volt deep cycle battery, due to their high reserve
capacity. Automotive batteries are recommended for only a short
period of time of an hour or less.
• 3 •
NOTE: 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.
When you turn on a device or a tool that runs on a motor, the device
basically goes through two stages:
Start Up – Requiring an initial surge of power (commonly 1.
known as the “starting or peak load”).
Continuous Operation – Power consumption drops (commonly 2.
known as the “continuous load”).
The wattage (WATTS) or amperes (AMPS) can normally be found
stamped or printed on most devices and equipment, or in the
user’s manual. Otherwise, contact the manufacturer to nd out
whether the device you want to use is compatible with a modied
sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x WATTS. In
general, the start up load of the device or power tool determines
whether your inverter has the capability to power it.
To calculate the continuous load: Continuous Load = AMPS x 120
(AC Voltage).
Always run a test to establish whether the inverter will
operate a particular piece of equipment or device. In the event of a
power overload, the inverter is designed to automatically shut down.
This safety feature prevents damaging the inverter while testing
devices and equipment within the wattage range of the inverter.
When using the vehicle’s 12 volt accessory port, this
inverter is designed to supply 60 to 70 watts when the vehicle is
not running. With the vehicle’s engine running, it can supply up to
100 watts. To use the full output, you must connect the inverter
directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings
for all vehicles. Some vehicles may allow the full output. If the
fuse blows when you switch on the device you are trying to use,
you have to either use a smaller device or you must connect the
inverter directly to the battery.

Doing so may cause the device to run warmer or overheat.
FASTENING THE INVERTER TO A FLAT SURFACE3.
For convenience, your inverter can be fastened to a at surface,
horizontally or vertically. The area where the inverter is to
be fastened must be dry, well ventilated and away from any
combustible material or fumes.
Turn off and disconnect the inverter.1.
Place the back of the inverter with the mounting bracket 2.
against a secure and at surface.
Attach the inverter to the at surface using corrosion-resistant 3.
screws.
CONNECTING INVERTER CABLES4.
The inverter and power source must be in the OFF mode.
Make sure you connect your inverter to a 12-volt
power supply only.
Inverter connection (Models PI-400, PI-750 and XI41B):
Locate the positive and negative plastic terminals located on the 1.
back of the inverter and remove the terminal caps completely.
Install the positive (red) cable ring lug onto the positive (red) 2.
terminal screw. Install the negative (black) cable ring lug onto
the negative (black) terminal screw. Tighten each terminal, so
that the cable cannot come loose.

battery charger, monitor the temperature of the battery charger for
If you are using the power inverter to operate a
about 10 minutes. If the battery charger becomes abnormally
warm, disconnect it from the inverter immediately.
NOTE: You can use an extension cord from the inverter to the
device without signicantly decreasing the power being generated
by the inverter. For best operating results, the extension cord
should be no longer than 50 feet.
Using the Inverter to operate a TV or audio device:
The inverter is shielded and ltered to minimize signal
interference. Despite this, some interference may occur with your
television picture, especially with weak signals. Below are some
suggestions to try and improve reception.
Make sure the television antenna produces a clear signal 1.
under normal operating conditions (i.e. at home plugged into
a standard 120-volt AC wall outlet). Also, ensure that the
antenna cable is adequately shielded and of good quality.
Try altering the position of the inverter, antenna cables, and 2.
television power cord. Add an extension cord from the inverter
to the TV so as to isolate its power cord and antenna cables
from the 12-volt power source.
Try coiling the television power cord and the input cables 3.
running from the 12-volt power source to the inverter.
Afx one or several “Ferrite Data Line Filters” to the television 4.
power cord. Ferrite Data Line Filters can be purchased at
most electronic supply stores.
NOTE: You may hear a “buzzing” sound being emitted from
inexpensive sound systems when operated with the inverter. This
is due to ineffective lters in the sound system’s power supply.
Unfortunately, this problem can only be resolved by purchasing a
sound system with a higher quality power supply or higher quality lter.

POWER SOURCE6.
To get the best performance out of your inverter, we recommend that
you use it with the vehicle’s engine running.
Your average automobile or marine battery at full charge will provide
an ample power supply to the inverter for approximately 3 hours when
the engine is off. 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.
If you decide to use the inverter while the engine is off, we
recommend you turn OFF the device plugged into the inverter
before starting the engine. To maintain battery power, start the
engine every 2 to 3 hours and let it run for approximately 10
minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when turning
over the engine, it may briey cease to operate as the battery
voltage decreases. While the inverter draws very low amperage
when not in use, it should be unplugged to avoid battery drain.
LED INDICATOR AND SHUTDOWN PROTECTION7.
The LED glows GREEN automatically when plugged into a 12-volt
DC source, but will not glow under the following conditions:
When the power input from the vehicle’s battery drops to 1.
approximately 10-volts, low battery shutdown occurs and
inverter shuts off. Solution: Recharge or Replace the battery.
When the power input from the vehicle’s battery exceeds 2.
15-volts, high voltage overload protection occurs. Solution:
Reduce the voltage range to between 12-volts and 14-volts.
The continuous load demand from the equipment or device 3.
being operated exceeds the continuous load rating of the
inverter being used. Solution: Use a higher capacity inverter
or lower rated device.
The case temperature becomes hot (exceeds 145°F). 4.
Solution: Allow the inverter to cool. Do not block the cooling
slots or air ow over and through the inverter. Reduce the
load on the inverter to the continuous rated output.
• 8 •
RESET: To reset after shutdown occurs:
Disconnect the inverter from the 12V power source.1.
Check the source of the problem and correct.2.
Reconnect the inverter to the 12V power source.3.
NOTE: If the red LED is lit and the green LED is not, see the
Troubleshooting section.
IF THE INVERTER FUSE BLOWS8.
Your power inverter is tted with a fuse, 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 the fuse does blow:
Disconnect the device or equipment immediately.1.
Find the source of the problem and repair it.2.
Install a new fuse (25-amp for Models PI-200, PI-400 and 3.
XI41B; 45-amp for Model PI-750). The fuse can be found on
the right side of the inverter. NOTE: If you are using the 12V
accessory plug to power the inverter, there is also a 15-amp
fuse in the end of the plug.
Do not install a fuse with a higher amp rating than
the original fuse, as this may damage the inverter and any product
you use with the inverter. Make sure to correct the cause of the
blown fuse before using the inverter again.
