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 combina-

tions, 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 mo-

tors 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 modified sine wave

inverter.

Attention: Always run a test to estab-

lish 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

2000-watt range.

If a device will not operate properly

when first connected to the inverter, turn

the inverter rocker switch ON (I), OFF

(O), and ON (I) again in quick succes-

sion. 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 applica-

tions only.

• Incorrect operation of your inverter

may result in damage and personal

injury. Electrical current on a 110-volt

circuit can be very dangerous.
