Led Indicator And Shutdown Protection - Schumacher Electric PI-70 Manual Del Propietário

If you decide to use the inverter while the engine is off, we rec-
ommend you turn OFF the device plugged into the inverter and
disconnect the inverter's plug from the 12-volt accessory outlet
before starting the engine. To maintain battery power, start the
engine every 2 to 3 hours and let it run for approximately 30
minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when
turning over the engine, it may briefly cease to operate as the
battery voltage decreases. While the inverter draws very low
amperage when not in use, it should be unplugged to avoid
battery drain.
7. LED INDICATOR AND SHUTDOWN
PROTECTION
The LED glows GREEN automatically when plugged into a 12-
volt DC source and will not glow under the following conditions,
(Note: On Model PI-120 a BLUE LED will glow):
1. When the power input from the vehicle's battery drops
to approximately 10-volts, low battery shutdown occurs
and inverter shuts off. Solution: Recharge or Replace the
battery.
2. When the power input from the vehicle's battery exceeds
15-volts, high voltage protection occurs. Solution: Reduce
the voltage range to between 12-volts and 14-volts.
3. The continuous load demand from the equipment or
device being operated exceeds the continuous load rating
of the inverter being used. Solution: Use a higher capacity
inverter or lower rated device.
4. The case temperature becomes hot (exceeds 145°F). So-
lution: Allow the inverter to cool. Do not block the cooling
slots or air flow over and through the inverter. Reduce the
load on the inverter to the continuous rated output.
