Important Safety Information
Introduction
WARNING Power inverters contain components
that tend to 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.
Caution: Rechargeable Appliances
Certain chargers for small nickel cadmium batteries
can be damaged if connected to the Cobra 2500 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 2500 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).
