INTRODUCTION
Congratulations! You have purchased one of the most sophisticated and reliable power inverters of the industry.
Incorporating the latest technologies, it will deliver years of trouble free operation for your truck, boat, RV or
other “OFF Grid” system.
1) In order to get the most out of your inverter, the installation procedure must be followed carefully.
Please thoroughly read this manual before installing and using your new inverter. It is important to
pay special attention to the CAUTION and WARNING statements in this manual as well as on the
inverter.
2) The electrical current at the input and output of your inverter may cause severe personal injury;
make certain that you have read and understood all the sections of this manual before installing and
using your inverter.
3) The inverter produces an electrical current similar to what’s found in most North American homes,
with all the accompanying hazards.
4) Be sure to install the product out of the reach of children.
5) Should the inverter be exposed to rain, moisture, or strong impact, have it inspected by a qualified
technician before use.

Disclaimer
The electrical code varies depending on location and the type of installation. Electrical installations must meet
local and national wiring codes and should be performed by a qualified electrician. Tundra International Inc. is
not liable for any incidental, consequential or other damages arising from the use, misuse or operation of this
product; including, without limitation, damages resulting from loss of use, cost of removal, installation, or
troubleshooting. All Tundra products specifications are subject to change without notice.

Output waveform
The AC output generated by your inverter is designed to provide a regulated RMS (Root Mean Square) output of
120 Volt/60Hz and its waveform is called a “Modified Sine Wave.” It is a stepped waveform suitable for most
AC loads and designed to have characteristics similar to sine waves delivered by public utility power services.
To read the output voltage correctly, you must use a true RMS reading voltmeter. Most AC voltmeters are
calibrated to read the average value of the waveform rather than the RMS value. Inappropriate meters may not
read the modified sine wave correctly (2-20 Volts lower than the actual value).
