Our Thanks to You

Introduction

Thank you for purchasing the Cobra Power

Inverter CPI490. Properly used, this Cobra product

will give you many years of reliable service.

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

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 user-

serviceable 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.

Nothing Comes Close to a Cobra®

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.

Proposition 65: 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 400 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.

Important Safety Information

Introduction

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 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.

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.

}A test load that can

be plugged into the AC

receptacle on the inverter

for short term testing at

a low power level.

To check your inverter’s performance before installation:

1. Turn the inverter off (see page 11

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 6

for details).

3. Connect cable 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 14

or power and protection indicators

section on page 12.

Installation Requirements

Installation

Nothing Comes Close to a Cobra®

Installation Requirements 

The inverter must be installed in an area that meets

all of the following requirements:

A. Dry

Do not place in an area where water can drip

or splash on the inverter.

B. Cool

Ambient air temperature should be between 30°F

and 105°F (0°C and 40°C). The cooler the better.

C. Ventilate

Allow at least one inch (three cm) of clearance around

the inverter for proper airflow. Make sure that ventilation

openings on the ends of the unit are not obstructed.

D. Safe

Do not install the inverter in the same compartment

as a battery or in any compartment that contains

flammable liquids such as gasoline.

E. Close to Battery

Install unit as close to battery as possible (without

being in the same compartment) to minimize the

length of cable required to connect the inverter to

the battery. It is better and cheaper to run longer

AC wires than longer DC wires (cables).

CAUTION To avoid fire, do not cover or obstruct

ventilation openings. Do not install inverter in a zero-

clearance compartment. Overheating may result.

CAUTION The inverter must only be connected to

batteries with a nominal output voltage of 12 volts.

It will not work with a 6 volt battery, and will be

damaged if it is connected to a 16 volt battery.

WARNING This unit contains components which

can produce arcs or sparks. To prevent fire or

explosion, do not install in compartments containing

a battery or flammable materials, or in a location

which requires ignition protected equipment.

Mounting 

To mount your inverter:

1. Place the inverter on a flat surface with the mounting

bracket against the mounting surface.

2. Mount to secure surface using mounting hardware

that is corrosion resistant (not included).

The inverter can be mounted horizontally or vertically.

Connecting Cables 

Power wire and wiring are very important to the

performance of the inverter. Because the inverter has a

low voltage, high current input, low resistance wiring is

essential between the battery and inverter. This is so it

can deliver the maximum amount of energy to the load.

Only use the cables provided with your power inverter.

To connect the cables between

the inverter and the battery:

1. Turn the On/Off Switch on the

inverter to the off position. If

the power source is a DC power

supply, switch it off as well.
