3. The continuous load demand from the equipment or
appliance being operated exceeds 400 watts.
4. The circuit temperature exceeds 145 ºF.
Attention: The PI-400 is fitted with a cooling fan that runs
as needed while the inverter is operating. If the cooling
fan is unable to maintain a cool enough temperature for
safe operation, the inverter will automatically shut down.
If the inverter automatically shuts down or a continuous
audible alarm is heard:
1. Turn the inverter rocker switch to the OFF (0).
2. Determine the source of the problem, and resolve it
before continuing to use the inverter.
Important Safety Measures
For the most effective use, place the power inverter on a
at surface.
Keep the inverter dry.
DO NOT allow it to come into contact with rain or moisture.
DO NOT operate the inverter if you, the inverter, the device
being operated or any other surfaces that may come in
contact with any power source are wet. Water and many
other liquids can conduct electricity, which may lead to
serious injury or death.
Do not place the inverter on or near heating vents, radia-
tors or other sources of heat.
Do not place the inverter in direct sunlight. The ideal air
temperature for operation is between 50º and 80ºF.
