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.
