How Your Cobra Power Inverter Works |
|
|
|
The Cobra power inverter is an electronic product that has |
|
|
|
been designed and built to take low voltage DC (Direct |
|
|
|
Current) power from your automobile or other low voltage |
|
|
|
power supplies and convert it to standard 115 volt AC |
|
|
|
(Alternating Current) power like the current you have in |
|
|
|
your home. This conversion process thereby allows you |
|
|
|
to use many of your household appliances and electronic |
|
|
|
products in automobiles, RVs, boats, tractors, trucks and |
|
|
|
virtually anywhere else. |

Important Safety Information
Introduction
Important Safety Information
•
Before installing and using your Cobra power inverter, please read these general precautions and warnings.
Caution and Warning Statements
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 Statements identify conditions that could result in personal injury or loss of life.
General Precautions
1.Never install the inverter in a boat’s engine compartment where gas and battery fumes are present.
2.Do not operate the inverter if it has been dropped or damaged in any way.
3.Do not open the inverter; it contains no userserviceable parts. Attempting to service unit could cause electrical shock.
NOTE Internal components remain charged after all power is disconnected.
4.Do not expose the inverter to rain, snow, bilge water or spray.
5.Do not obstruct the ventilation openings.
6.Do not install the inverter in zero-clearance compartment.
CAUTION This inverter should be used in negative ground applications only.

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 1500 watt inverter. Two particular types of equipment are prone to this problem:
Plug In Directly
Dangerous Voltages
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.
Important Safety Information
Introduction
Cobra 1500 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).

Power Source |
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. |
£Cables to connect the power source to the inverter (not included).
The cables must be as short and thick as possible in order to reduce the voltage drop between the power source and the inverter when it is drawing current from the power source.
If the cable suffers an excessive voltage drop, the inverter may shut down when drawing higher currents because the voltage at the inverter dropped below 10 volts.
#4 AWG stranded copper cable is recommended.
It should be no longer than four feet (one and one-half meters).
The end of the cable that connects to the inverter must have its insulation stripped off for about one-half inch (one and one-half cm) back from the end, exposing the bare copper.
The other end of the cable, which connects to the power source, must be terminated with a lug or other connector that provides a secure, low resistance connection.
For example, if the power source is a battery, the cable must be terminated with a battery terminal that clamps to the post on the battery.
Quick Evaluation
Before Installation
Introduction
£A test load that can be plugged into the AC receptacle on the inverter for short term testing at a low power level. The following cables are recommended for testing low power level test loads only.

To check your inverter’s performance before installation:
1. Turn the inverter off (see page 14
for details). If the power source is
a DC power supply, switch it off
as well.
2. Connect cables to power input
terminals (see page 8 for details).
3. Connect cables to power source
(see page 8 for details).
4. Check to make sure all connections are secure.
5. Turn the inverter on. If the power
source is a DC power supply,
switch it on first.
6. Plug in the test load.
The inverter should supply power
to the load. If the inverter is not
working properly, refer to the troubleshooting guide on page 20
or power and protection indicators section on page 16.
NOTE A USB device can be used to check the output of the USB Outlet.
