Installation Precautions

Page 2 For technical questions, please call 1-800-444-3353. Item 69662

1. DO NOT INSTALL THIS INVERTER INTO A

BUILDING’S ELECTRICAL SYSTEM. This inverter
is a vehicular accessory. It is not designed
to be safely used in a building’s electrical
system and has not been evaluated to meet
building wiring codes. Improper application
may create a fire or electric shock hazard.

2. To allow proper cooling, install in indoor well­ventilated area and do not cover ventilation openings
or cooling fins. Do not install in engine compartment.

Especially avoid placing the Inverter on carpets
and rugs; they are not only flammable, but
they also obstruct vents underneath it.

3. Keep combustible materials and gasses away
from the inverter. The inverter produces sparks
and heat during operation and can start a fire.

4. Connect to 12 VDC power supply only. A power
supply with lower voltage will not operate the Inverter
correctly, and higher voltage could damage the unit.

5. Connect input polarity properly. Incorrect connection
will damage inverter and void warranty.

6. Do not use in a marine application.
This inverter is not intended to withstand the highly
corrosive conditions in marine applications and
would quickly be rendered inoperable or unsafe.

7. Keep inverter dry and clean. Do not expose
to rain, snow, spray, bilge water or dust.

8. Use cables that are thick enough. The more power
(amps) or the longer the cables, the thicker they
need to be to prevent overheating and fire.

9. Install as close to DC source as possible, but not
in a closed area with vented lead-acid batteries.
Vented lead-acid batteries release explosive
hydrogen gas that can be ignited by the inverter.

SAFETYOPERATIONMAINTENANCE SETUP

10. Mount inverter horizontally.

11. Verify that installation surface has no hidden
utility lines before drilling or driving screws.

12. This product is not a toy. Keep it away from children.

13. Do not use with positive ground electrical
systems. (Most automobiles, trucks, and
RV’s have negative ground systems.)

14. The positive (+) battery on the Inverter must be the
last connection made, and must be connected before
the Inverter is turned on. There may be a small
spark during the final connection. This is normal.

15. Properly ground the inverter’s case
as explained in this manual.

Battery Precautions

1. Wear splash-resistant ANSI-approved
safety goggles and electrically insulated
gloves while working near batteries.

2. Charge, store, and maintain batteries
according to supplier’s instructions.

3. Locate batteries in a clean, well-ventilated area,
away from ignition sources and flammable
materials. Vented lead-acid batteries release
explosive hydrogen gas while charging.

Operation Precautions

1. Multiple outlet power strips with switches and
circuit breakers only interrupt power to the “hot”
receptacle terminals. The “neutral” terminals
remain powered with respect to the “ground”
terminals. So strip switch may be off, but
part of appliance may still be powered.

2. Inspect supply connections before use to ensure
they are tight and that insulation is not damaged.

4. Only connect similar batteries together. Do
not connect old and new batteries together,
wet and gel cells together, or batteries
of different capacities together.

5. Use only 12 V batteries with this item.

6. Connect batteries in parallel ONLY (negative

terminals together to one cable; positive
terminals together to the other cable).

7. Install a properly rated fuse on the
positive output of the battery bank.

4. Some rechargeable tools and appliances can
damage the Inverter. Check the temperature of the
device several times when it is charging. If the device
becomes extremely hot; turn the power off, remove
the device, and do not use with the Inverter again.

5. Check for breakage of parts and any other
condition that may affect the Inverter’s operation.
If damaged, have it repaired before use.

3. Do not use this inverter to power sensitive
devices such as medical devices or computers.
Do not use in ignition protected areas.

6. Do not attempt to power a device, or combination
of devices, that will require more than the
rated output of this inverter. This may damage
the inverter or the attached devices.

Page 3For technical questions, please call 1-800-444-3353.Item 69662

7. Appliances such as microwave ovens will
normally draw more than their rated current.
For example: A typical 600 watt microwave
oven will draw approximately 1,000 watts.

9. Some fluorescent lamps may not operate
properly with this type of inverter. If the bulb
appears to be too bright, or fails to light,
do not use the lamp with this inverter.

8. Do not attach a battery charger if the charger

SAFETY OPERATION MAINTENANCESETUP

carries a warning that dangerous voltages
are present at the battery terminals.

Service Precautions

1. DO NOT OPEN HOUSING.

Contains no user-serviceable parts.

Internal parts may be electrified, even
with unit off and power disconnected.

2. Maintain labels and nameplates on the
Inverter. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.

SAVE THESE INSTRUCTIONS.

Symbology

10. Some fans with synchronous motors may slightly
increase in speed when powered by the inverter.
This is not harmful to the fan or to the inverter.

11. Inverter will consume some power while on, even
without loads attached. Turn inverter off after use.

3. Have your Inverter serviced by a qualified

repair person using only identical
replacement parts. This will ensure that

electronic equipment, transformers, and motors. Do
not use to power sensitive devices such as medical
equipment or computers. Some audio equipment may
perform poorly if run on Modified Sine Wave power.

SAFETYOPERATIONMAINTENANCE SETUP

1.

This inverter’s output is a Modified Sine Wave.
Power from most electric utilities is a Sine Wave.

Note: Only multimeters identified as “TRUE RMS“
will read Modified Sine Wave voltage accurately.

3. Sine Wave inverters provide power that is identical

to, or even better than, the power supplied by
your power company. Motors start easier and run
cooler under Sine Wave power. Certain devices,
such as laser printers, variable speed motors and
digital clocks, require sine wave power to operate
properly. Sine wave inverters are typically more
expensive for their capacity than other inverters.

Installation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

SAFETY OPERATION MAINTENANCESETUP

TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Make sure that the Power Switch is in the off-position and unplug the tool from
its electrical outlet before performing any procedure in this section.

Note: For additional information regarding the parts listed in the following pages,

refer to Parts List and Diagram on page 11.

CAUTION! This Inverter must only be connected

to batteries with a output voltage of 12 volts DC.
Lower voltage will not operate the Inverter properly,
and more voltage could damage the Inverter
or the device being powered. Do not use this
Inverter with positive ground electrical systems.

The Inverter is configured to have a number of
shut-down points, for the safety of the operator,
the unit, and the devices being used with it.

• If the DC input voltage drops too low, the
alarm on the Inverter will sound. Should the
input voltage drop further, the Inverter will
shut down automatically to prevent permanent
battery damage. Recharge the battery soon.

• If the DC input voltage exceeds 15V the
Inverter will shut down automatically.

• If the output load power rises higher
than the rating power of the Inverter; the
unit may shut down automatically.

• The Inverter may automatically shut down
if its internal temperature gets too high.

Note: Even though this inverter has built-in mechanisms
to minimize damage, these situations should be avoided
because they can still damage the inverter or battery.

1. Place the Inverter on a dry, level, non-flammable,
stable surface. Make sure the Inverter has
adequate ventilation and is not in direct sunlight.

2. Connect one end of a ground wire (not included,
use at least recommended wire thickness from
specification sheet) to the wing nut located on the
back of the Inverter. Then connect the other end
of the ground wire to a paint/rust free grounded
metal surface, such as the vehicle chassis.

3. Battery Type Selection:

• Use only deep cycle lead-acid batteries with this
inverter, such as 12 volt marine/RV deep-cycle
batteries. Do not use automotive, engine starting
(SLI), or maintenance-free wet cell batteries with
this inverter; they are designed for repeated,
shallow discharge and will wear out quickly.

• Gel and AGM (Absorbed Glass Mat)
batteries can be used with this inverter, but
they require special charging procedures.
Refer to battery supplier’s instructions.

4. Battery capacity selection:

does not have a capacity this large individually,
use a bank of batteries as explained below.

5. Battery Bank assembly instructions:

a. Read the following safety rules before

assembling the battery bank:

• Connect batteries in parallel (negative
terminals together to one cable;
positive terminals together to the
other cable) as shown in Battery
Bank Example illustration ONLY.

• Do not connect 12V batteries in series (from
negative of one battery to the positive of the
next). This connection can result in voltage
high enough to cause ELECTROCUTION.

• Wear splash-resistant ANSI-approved
safety goggles and electrically insulated
gloves while assembling battery bank.

• Only connect similar batteries together in a
battery bank. Do not connect old and new
batteries together, wet and gel cells together,
or batteries of different capacities together.

• Connect all batteries in the battery bank together
using cables of the thickness recommended on
the specification sheet or thicker. Since amp
draw on this low-voltage circuit will be very
high, thinner cables present a fire hazard.

Page 6 For technical questions, please call 1-800-444-3353. Item 69662

• Locate battery bank in a clean, well­ventilated area, away from ignition sources
and flammable materials. Batteries release
explosive hydrogen gas while charging.

• Charge, store, and maintain batteries
according to supplier’s instructions.

c. Then connect all the negative

terminals to one another.

d. Connect the negative and positive output cables

to opposite ends of the bank. Do not allow

the output cables to touch one another.

e. Test the voltages at the output cables to help

ensure that the battery bank is properly wired.
If the voltage is higher than 13 volts, then part
of the battery bank is likely connected in series
(a negative terminal of one battery attached
to a positive terminal of another) instead of in
parallel. Carefully examine the diagram and
correct the wiring before attaching to the inverter.

6. Turn the inverter’s Switch off.
