Caution: Rechargeable Appliances
Certain rechargers for small nickel cadmium bat-
teries can be damaged if connected to the Cobra
1000W inverter.Two particular types of equip-
ment 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 charges have a
WARNING label stating that dangerous volt-
ages 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 that 30
volts) the inverter will have no problem
powering it safely.

To make the most of this inverter,it must be
installed and used properly.Please read the
installation and operating instructions carefully
before installing and using it. Special attention
must be paid to the CAUTION and WARNING
statements in the manual.CAUTION statements
specify conditions which could cause damage to
the unit or other equipment.WARNING state-
ments identify conditions that could result in
personal injury or loss of life.
Cobra 1000W Output Waveform
The output waveform is referred to as “square
wave”or “modified sine wave.”It is a stepped
waveform designed to have characteristics simi-
lar to the sine wave shape of utility power.A
waveform of this nature is suitable for most AC
loads (including linear and switching power sup-
pliers used in electronic equipment,transformers
and motors).
