Our Thanks to You

Introduction

Thank you for purchasing the Cobra CPI 1000 inverter. 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.

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 1000 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 1000 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.

£ Cables to connect the power source to the inverter.

Cables are supplied with the unit that are two feet long overall from the tip of the clamp shown to the stripped and tinned end for insertion in the Input End of the unit.

If user supplied cables are to be used, they 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.

£ 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.

Test Load Minimum

Power Cable Size

100W # 16 AWG copper 250W # 12 AWG copper 500W # 8 AWG copper

ower Source

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.
