Safety Features
The led Indicator light will turn from GReeN to Red and
the inverter will automatically tur n itself off when:
1. The power input from the battery drops to approximately
10 volts. (When the power input drops to approximately
10.5 volts, an alarm will sound for an extended period).
2. The power input from the bat tery exceeds 15.5 volts.
3. The continuous load de mand from the equipment or
device being operated exceeds 1500 watts.
4. The case temperature exceeds 140 º F.
Attention: The PI-1500 is tted with cooling fans that run
as needed while the inverter is operating. If the cooling
fans are unable to maintain a co ol enough temperature
for safe operation, the inverter w ill automatically shut
down. If the inverter automatically shuts down or a con-
tinuous audible alarm is heard:
1. Turn the inverter rocker switch to the oFF (o).
2. determine the source of the problem, and res olve it
before continuing to use the inverter.
How Do Power Inverters Wor k?
There are two stages involved in transforming 12-volt dC
(or battery) power into 110V AC (household voltage):
StAGe 1: The PI-1500 power inverter uses a dC to d C
transformer to increase the 12-volt dC input voltage from
the power source to 145-volts d C.
