To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x WATTS. In
general, the start up load of the device or power tool determines
whether your inverter has the capability to power it.
To calculate the continuous load: Continuous Load = AMPS x
120 (AC Voltage).
ATTENTION: Always run a test to establish whether the inverter
will operate a particular piece of equipment or device. In the
event of a power overload, the inverter is designed to automati-
cally shut down. This safety feature prevents damaging the
inverter while testing devices and equipment within the wattage
range of the inverter.
IMPORTANT (Models IP-120 and IP-140): This inverter is
designed to power 100 watt devices or less when used with the
vehicle 12 volt accessory port. To use the full output you must
purchase a 12 volt accessory outlet to battery clips adapter
(Schumacher Model SAC-103) and connect the inverter directly
to the battery.
NOTE (Models IP-120 and IP-140): The 100 watt limit is to ac-
commodate 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 bat-
tery 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 follow-
ing devices:
1.
Switch Mode Power Supplies;
2.
Linear Power Supplies;
3.
Class 2 Transformers;
