Schumacher PI-1500 User Manual
1500 Watt DC to AC Power Inverter
Conver t s 1 2 V D C B a t t e r y Power
to 110V AC Home Power
OWNER'S MA NUA L
– SAVE THESE INSTRUCTIONS –
The recommended source of power is a 12-volt deep-cycle battery
due to their high reserve power capacity. Automotive batteries
are recommended for only a short period of time of an hour or less.
MODEL PI-1500
00-99-000628/0206
The advanced surge capacity of the PI-1500 power
inverter gives it the means to start most electrical devices
including: color televisions, TV/VCR/DVD combinations,
small microwaves, refrigeration electric coolers, small air
conditioners.
Warning: Handling the cord on this product or cords
associated with accessories sold with this product, may
expose you to lead, a chemical known to the State of
California to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.
Important Safety Measures
Precautions to keep in mind before and while using
your power inverter:
• For the most effective use, place the power inverter on a
at surface.
• Keep the inverter dry.
• DO NOT allow it to come into contact with rain or moisture.
• DO NOT operate the inverter if you, the inverter, the device
being operated or any other surfaces that may come in
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 other sources of heat.
- 1 -
• Do not place the inverter in direct sunlight. The ideal air
temperature for operation is between 30º and 105ºF.
• Keep the inverter well ventilated in order to properly disperse heat generated while it is in use.
• While in use, make sure there are several inches of clearance around the top and sides of the inverter.
• Do not use the inverter near ammable materials.
• Do not place or install the inverter in areas such as battery or engine compartments where fumes or gases may
accumulate.
• Only connect the power inverter to a 12-volt battery. Connecting to a 6V or 16V battery will cause damage to the
inverter.
• Only connect the power inverter to a 12-volt battery with
the supplied 12-volt power cords. Make sure the cord
connections to the inverter are tight.
• Do not modify the positive and negative cables or plug in
any way.
• Make sure the power consumption of the device or equipment you want to operate is compatible with the capacity
of the inverter, and does not exceed 1500 watts.
• If you are using the power inverter to operate battery
charger, monitor the temperature of the battery charger for
about 10 minutes. If the battery charger becomes abnormally warm, disconnect it from the inverter immediately.

• If you are powering the inverter with an automobile or marine battery, start the engine every 30 to 45 minutes and
let it run for about 10 minutes to recharge the battery.
• If you hear a continuous alarm or automatic shut down, turn
the inverter OFF immediately. Do not restart the inverter
until the source of the problem has been identied and
corrected.
• Disconnect the inverter when not in use in order to avoid
battery drain.
Before Using PI-1500
It is important to know the continuous wattage of the
device you plan to use with the inverter. The PI-1500
must be used with devices drawing 1500 watts or less. If
the wattage is not marked on the device, an estimate can
be made by multiplying the AC input current (Amps) by
the AC voltage (110V).
Devices like TVs, fans or electric motors require additional power to start (commonly known as the “starting
or peak power”). The PI-1500 can supply a momentary
surge in wattage; however even devices rated less than
the maximum 1500 watts can exceed the inverters surge
capability and cause an automatic overload shutdown.
Make sure the device you are using is compatible with a
modied sine wave inverter.
Attention: Always run a test to establish whether the inverter will operate a particular piece of equipment or device.
- 3 -
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 1500-watt range.
If a device will not operate properly when rst connected
to the inverter, turn the inverter rocker switch ON (I), OFF
(O), and ON (I) again in quick succession. If this procedure is not successful, it is likely that the PI-1500 inverter
does not have the required capacity to operate the device
in question.
Important: Make sure you connect your inverter to a
12-volt power supply only. Connecting to another voltage
including any AC power source, will result in damage.
• Do not try extending or otherwise changing the 12-volt
power cord of your inverter.
• Install in negative ground applications only.
• Incorrect operation of your inverter may result in
damage and personal injury. Electrical current on a
110-volt circuit can be very dangerous.
Fastening the PI-1500 to a Flat Surface
For convenience, the PI-1500 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 products or fumes.
1. Turn off the PI-1500.

2. Place the back of the PI-1500 with the mounting bracket
against a secure and at surface.
3. Attach the inverter to the at surface using corrosion
resistant screws.
Inverter Features:
A. ON/OFF Rocker Switch – Turns inverter on and off.
B. LED Indicator Light – (Green = power ON, Red =
Overload, interruption in power).
C. Two, 110V GFCI AC Outlets
D. One Pair, 12-Volt Power Cords
E. Two, High Speed Cooling Fans – keeps inverter cool.
The speed of the fan is faster as the load increases. Fan
does not run when inverter turned off.
F. Analogic Output Power Display - shows 110V AC
continuous power consumed.
G. Positive Battery Cable Terminal (Red) – accepts positive
connector cable.
H. Negative Battery Cable Terminal (Black) – accepts
negative connector cable.
I. Ground Terminal – grounds inverter to reduce electrical
shock.
