1 Introduction

Congratulations! You have purchased one of the most sophisticated and reliable power inverters on the market today.
Incorporating some of the latest technological developments, it will give years of trouble free operation for your truck, boat, R.V.
or other.

In order to get the most out of your inverter, the installation procedure must be followed carefully and it must also be properly
used. 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. Should the inverter be exposed to rain,
moisture, or strong impact, have it inspected by a qualified technician before use.

WARNING! The electrical current at the entrance and exit of your inverter may cause severe personal injury;

make certain that you have read and understand all the parts of this manual before installing and
using your inverter.

WARNING! The inverter produces an electrical current similar to that found in most North American homes, with

all the accompanying dangers. Be sure to install the product out of the reach of children.

1.1 Disclaimer

Electrical codes vary 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.

The inverter’s specifications are subject to change without notice.

1.2 Output waveform

The AC output of your inverter is regulated to 120 volts and its waveform is called a “Modified Sine Wave.” It is a stepped
waveform, suitable for most AC loads, designed to have characteristics similar to sine waves delivered by utility power. Note that
our modified sine wave output power is much more efficient than the “square wave” generated by other inverters on the market
today.

The modified sine wave generated by your inverter is designed to have an RMS (Root Mean Square) voltage of 120 volts, the
same voltage as that coming out of standard household power. Most AC voltmeters are sensitive to the average value of the
waveform rather than the RMS value. They are calibrated for RMS voltage assuming the voltage waveform is “ pure sine wave.”
These meters may not read the modified sine wave correctly; they will read about 2-20 volts lower. To read the voltage correctly,
you must use a true RMS reading voltmeter.

2 Front , rear panel & remote control

FRONT PANEL
ON/OFF switch: The ON/OFF switch turns the inverter’s control circuit ON and OFF. It does not disconnect power

from the inverter; you must disconnect the AC (120 volts) and DC (24 volts) power before
working on any circuits connected to the inverter. When the switch is on but no power is being

supplied to a load, the inverter draws less than 500 mA. This is a very low current draw but left in this
state the inverter will eventually drain your batteries until its automatic shut down at 22 volts (see

4.3).

AC Outlets: The maximum output of your inverter is assumed to go through the two AC outlets. HD Models are

also equipped with one hard wire outlet which can be used as the only output socket.

CAUTION! Leave in the OFF position during the installation.

REAR PANEL

Chassis ground screw: The chassis ground screw must be properly connected to the chassis of your vehicle before operating

the inverter.

Fan(s): In order for the inverter to properly operate, the fan(s) opening must never be obstructed. Allow at

least six inches of clearance around the inverter for airflow. All fans are thermostatic and operate
upon the interior temperature of inverter.

REMOTE CONTROL

ON/OFF: Your inverter is equipped with one 6 meters jack remote switch. The remote switch allows you to

mount your inverter out of sight and turn it ON or OFF from a convenient location. The ON/OFF
switch on the inverter’s front panel must be turned on for the remote to be operational.

Input Voltage: By pressing the “SELECT” button until the “INPUT VOLTAGE ” light comes on, the battery voltage

indicator displays the voltage at the input terminal of the inverter. Usually this voltage is very close to
the battery voltage and the difference, if any, is caused by the resistance of the cables and
connections. A regular maintenance will contribute to minimize the possible resistance (see 5).

Output Power: By pressing the “SELECT” button until the “OUTPUT POWER” light comes on, the watts indicator

displays the current provided by the inverter in KW. 1 KW = 1000 watts. If you read 1.20, it means
the inverter is providing 1200 watts.

“FAULT” light: An audible alarm will sound announcing a faulty condition such as: low or high battery voltage and

overload.

“OVERTEMP” light: An audible alarm will sound announcing an overtemp condition.

“LVP” on display: Indicates the inverter is in Low input Voltage Protection mode (see 4.3).

“OLP” on display: Indicates the inverter is in High input voltage Protection mode or if your consumption exceeds the

nominal capacity of the inverter (see 4.3).

3 Permanent Installation

The use of the Tundra International installation kits is strongly recommended. These complete installation kits are custom

designed to maximize performance. It has been developed to promote safe installation and to help eliminate the difficult task of
sourcing the requisite and right material.

- Open end wrench set

- Side cutters

- Power drill

CAUTION! Before installation, make sure that the inverter is turned “OFF.”

3.3 Where to install

Your inverter should be installed in a location that meets the following requirements:

- Dry: Keep the inverter away from any water or moisture.

- Cool: Ambient air temperature should be between 32 and 85 degrees Fahrenheit (0 and 30o Celsius).

- Ventilated: Ensure that the unit is located in a well-ventilated compartment. At least 6 inches of clearance are

required around the inverter for air flow. Verify that all ventilation openings on the unit (front and rear
panels) are not obstructed.

CAUTION! To avoid fire hazards and/or overheating, do not cover or obstruct any ventilation openings. Do not

install the inverter in a zero clearance compartment.

- Safe: Do not install the inverter in the same compartment as batteries, or in any compartment capable of

storing flammable liquids (such as gasoline). Power inverters may produce sparks that can result in fire
if exposed to flammable vapors.

WARNING! This equipment contains components that tend to produce arcs or sparks. To reduce the risk

of fire or explosion, do not install in a compartment containing batteries or flammable
materials, or in a location that requires ignition protected equipment.

- Close to batteries: Install the inverter as close as possible to the batteries (but not in the same compartment) in order to

minimize the cable length required to connect the inverter to the batteries. It is better and cheaper to run
longer AC wire (between the inverter and your appliances) than DC cables (between the inverter and
the batteries).

3.4 Mounting the inverter

When you have decided where to place it, mount the inverter on a flat surface using the mounting flanges. Mounting hardware
should be corrosion resistant, and 1/4” or larger. The inverter may be mounted on a vertical surface (the fans’ opening must not
point up or down) or on a horizontal surface. Upside down installation is not recommended, as it may put too much stress on the
housing of your power inverter.

If your inverter is equipped with a remote control, plug its cable into the remote switch jack on the front or rear panel of the
inverter.

Close to the inverter, drill two holes in the truck’s floor and install the two strain reliefs about 3 inches apart (Figure 3).
