Important - Schumacher Electric PI-750 Manual Del Usuario

This safety feature prevents damaging the inverter while testing devices and equipment
within the wattage range of the inverter.
When using the vehicle's 12 volt accessory port, this inverter is designed to supply
60 to 70 watts when the vehicle is not running. With the vehicle's engine running,
it can supply up to 100 watts. To use the full output, you must connect the inverter
directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles.
Some vehicles may allow the full output. If the vehicle fuse blows when you switch
on the device you are trying to use, you have to either use a smaller device or you
must connect the inverter directly to the battery.
IMPORTANT: This inverter uses a modified sine waveform (diagram A) which is not
quite the same as power company electricity (diagram B). For the following devices,
we strongly recommend that you use caution and check the device's manual to
make sure it is compatible with modified sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers
Using the inverter with any of these devices may cause the device to run warmer
or overheat.

IMPORTANT: If you are using the power inverter to operate a battery charger,
monitor the temperature of the battery charger for about 10 minutes. If the battery
charger becomes abnormally warm, disconnect it from the inverter immediately.
NOTE: You can use an extension cord from the inverter to the device without
significantly decreasing the power being generated by the inverter. For best operating
results, the extension cord should be no longer than 50 feet.
