Important Safety Information
Introduction
WARNING Power inverters contain components
that can produce arcs or sparks. To prevent fire
or explosion, do not install the inverter in areas or
compartments containing batteries or flammable
materials or in locations that require ignition-
protected equipment.
WARNING To reduce the risk of fire, do not cover
or obstruct the ventilation openings. Do not install
inverter in zero-clearance compartment.
Warning:Wash Hands After Handling Power Cord
The power cord on this product contains lead, a chemical
known in the state of California to cause birth defects or
other reproductive harm.
Caution: Rechargeable Appliances
Certain chargers for small nickel cadmium batteries can be
damaged if connected to the Cobra 800 watt inverter. Two
particular types of equipment are prone to this problem:
1. Small battery-operated
appliances such as flashlights,
razors, and night lights that
can be plugged directly into
an AC receptacle to recharge.
2. Certain battery chargers for
battery packs used in hand
power tools. These chargers
have a WARNING label stating
that dangerous voltages are
present at the battery terminals.
This problem does not occur with the vast majority of
battery operated equipment. Most use a separate charger
or transformer that is plugged into the AC receptacle and
produces a low voltage output. If the label on the AC
adapter or charger states that it produces a low voltage
AC or DC output (less than 30 volts), the inverter will
have no problem powering the adapter safely.
Cobra 800 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).
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.
The provided two foot direct-to-battery 12 gauge cable.
Only use the cable provided with
your inverter.
A test load that can be plugged into the AC receptacle on
the inverter for short term testing at a low power level.
