Schumacher owner manual Operating Instructions Models PI-70 and PI-140

This safety feature prevents damaging the inverter while testing devices and equipment within the wattage range of the inverter.

IMPORTANT (Models PI-120 and PI-140): This inverter is designed to power 100 watt devices or less when used with the vehicle 12 volt accessory port. The 100 watt limit is to accommodate the fuse ratings for all vehicles. Some vehicles may allow the full output. If the fuse blows when you switch on the device you are trying to use, you have to either use a smaller device or you must purchase the 12 volt accessory outlet to battery clips adapter (Schumacher Model SAC-103) and connect the inverter directly to the battery.

IMPORTANT: This inverter uses a nonsinusoidal waveform. Therefore we do not recommend you use it to power the following devices:

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.Transformerless battery chargers

Doing so may cause the device to run warmer or overheat.
