Model PSI-2000
2000 Watt DC to AC Power Inverter
Converts 12V DC Battery Power Into
110-120V AC Home Power
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.

The advanced surge capacity of the PSI-2000 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.
A. BEFORE USING PSI-2000
It is important to know the continuous
wattage of the device you plan to use
with the inverter. The PSI-2000 must be
used with devices drawing 2000 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 PSI-2000 can
supply a momentary surge in wattage;
however even devices rated less than
the maximum 2000 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 par ticular 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
2000-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 PSI-2000 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.

B. FASTENING THE PSI-2000 TO A FLAT SURFACE
For convenience, the PSI-2000 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 PSI-2000.
2. Place the back of the PSI-2000
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. Two Pairs, 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. Two, Po sitive Bat t e r y Cable
Terminals (Red) – accepts positive
connector cable.
H. Two, Negativ e Bat t e r y Cable
Terminals (Black) – accepts negative
connector cable.
I. Ground Terminal – grounds inverter
to reduce electrical shock.
C. GROUNDING THE PSI-2000
To avoid electrical shock, it is necessary to ground the PSI-2000 Inverter
as well as the device powering it. The
inverter should be grounded using #8
AWG copper wire (not included).
NOTE: Do not turn on the inverter or the
power source until the inverter and the
power source are grounded.
1. Turn off the PSI-2000.
2. Locate the chassis ground screw
underneath the negative terminal on
the left side of the inverter. Unscrew
the two hex nuts and one washer.
3. Strip the insulation of the wire back
1.5 inches and in between the two
washers, wrap the bare end of the
#8 AWG copper wires around the
threaded screw extension.
4. Holding the wire in place, screw
the hex nut on the threaded screw
extension and then screw on the
last hex nut to secure the wire
connection.
5. Using the other washer and hex nut,
secure the opposite end of the wire
and attach it appropriately so the
inverter is grounded correctly.
a. Vehicle – connect to the chassis
or unpainted frame part or engine
block of vehicle.
b. Boat – connect to boat grounding
system.
c. Fixed location – connect to a
ground rod or other appropriately
rated ground.
