Quick Evaluation
Before Installation
Introduction
Cobra 400 Watt Output Waveform
Some very sensitive electronic equipment may not operate
satisfactory on "square wave" or "modified sine wave."
The output waveform is referred to as "square wave" or
"modified sine wave." It is a stepped waveform designed to
have characteristics similar to the sine wave shape of utility
power. A waveform of this nature is suitable for most AC
loads (including linear and switching power suppliers used
in electronic equipment, transformers and motors).

Quick Evaluation Before Installation

This section provides you with basic information about the
inverter and how to check its performance before installation.
Be sure to have on hand:
A 12 volt DC power source (such as a vehicle battery).
Power Supply
The provided two foot cigarette lighter cable and
two foot direct-to-battery 12 gauge cable.
Only use the cables provided with your inverter.
The cigarette lighter cable is suitable for operating the
inverter at loads up to 150 watts. Connect by securely
inserting the plug into the cigarette lighter socket.
Cig. Lighter Cable
CAUTION Do not use the cigarette lighter cable
for loads higher than 150 watts. When connecting
loads larger than 150 watts, please connect the
inverter directly to the battery.
The power source must provide
between 11 and 15 volts DC and
be able to supply enough current to
run the test load. As a rough guide,
divide the wattage of the test load by
10 to get the current (in amperes)
the power source must deliver.
