• If you are powering the inverter with an automobile or ma-
rine 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 identified 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 addi-
tional 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
modified sine wave inverter.
Attention: Always run a test to establish whether the invert-
er will operate a particular piece of equipment or device.
