IMPORTANT PRODUCT /SAFETY INFORMATION

Before installing and using your Cobra power inverter, please read these general precautions and warnings.

Caution and Warning Statements 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.

3. Do not expose the inverter to rain, snow, bilge water or spray.

4. Do not obstruct the ventilation openings.

5. Do not install the inverter in zero-clearance compartment.

6. Do not allow water or liquids in contact with the power inverter

7. Do not use appliances with damaged or wet cords.

CAUTION: This inverter should be used in negative ground applications only.

CAUTION: The inverter must only be connected to batteries with a nominal output voltage of 12

volts. Do not connect the power inverter to a 6 Volt battery and will be damaged if connected to a 24 Volt battery.

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 avoid fire, do not cover or obstruct the ventilation openings. Do not install the power

inverter in a tight space or closed compartment where airflow may be restricted.

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 a Cobra PRO Power 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 PRO Output Waveform

Some very sensitive electronic equipment may not operate satisfactory on the output waveform referred to as "modified sine wave" which this inverter is designed. 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).

PENTAGON PROTECTION®

Cobra power inverters provide five levels of protection:

1. Over-Temperature: Auto-shut off will occur when the safe operating temperature has been exceeded.

2. Reverse Polarity: The inverter will not operate if connected incorrectly to the power source.

3. Over-Voltage: Auto-shutdown will occur if the DC input exceeds safe operating levels.

4. Low Voltage Alarm: The inverter will sound an alarm to indicate a low battery voltage condition.

5. Low Voltage Cutoff: The inverter will automatically shut off to prevent a dead battery condition.

For detailed specifications go to Specifications section of this manual, starting on page 25.

GETTING STARTED

This section provides you with the basic information about the inverter and a few tips before installation.

To get started, you will need:

1. A 12 Volt DC battery (i.e. vehicle battery). In order to understand how much current your battery

must deliver, divide the number of Watts from your AC appliance or device by 10.

2. Cables to connect your inverter to the vehicle battery. These come with your PRO Inverter and

provide a length of 48".

DETERMINING THE POWER REQUIREMENTS FOR YOUR PRO INVERTER

Before you turn on your power inverter and plug in an appliance or device, you will want to understand its power requirements.

To determine the requirements, you will need to know the Watts of your device. This can be calculated by multiplying the Amps by 110 Volts (See Below).

POWER CONSUMPTION

For each piece of equipment you will be operating from the power inverter, you must determine the battery’s reserve capacity (how long the battery can deliver a specific amount of current – in automotive batteries, usually 25 ampere) or ampere-hour capacity (a measure of how many amperes a battery can deliver for a specified length of time).

Example – Ampere-hour capacity: a battery with an ampere-hour capacity of 100 ampere-hours can deliver 5 ampere for 20 hours before it is completely discharged.

To determine the battery ampere-hour capacity you require:

1. Determine how many Watts each piece of equipment consumes. This can normally be found on the

product label. If only the Amperage is provided, then multiply the Amps by 115 to determine the

power in Watts.

2. Estimate how long you need your appliance to run.

3. Now calculate the Amp-hour rating for the battery. You can do this by multiplying the total AC

load (in Watts) by the length of time (in Hours) needed to run your appliance. This will give you

the Watt-Hours needed.

4. Divide the watt-hours by 10 to determine how many battery (12 volt) ampere-hours will be consumed.

Multiply: AC AMPS X 110 (AC Voltage) = WATTS. This formula yields a close approximation of the continuous load of your appliance.

Multiply: WATTS X 2 = Starting load for most appliances, tools and devices. This formula yields a close approximation of the starting load for most appliances. Exceptions are motorized appliances such as pumps, freezers, and air conditioners. These appliances can have startup loads of up to eight times the rated Watts.

For electrically sensitive equipment, contact the manufacturer to determine if the device you are using is compatible with modified sine wave AC. If not, then a Pure Sine Wave Inverter is recommended.

Determining the DC Power Requirements

Your inverter requires the input of a 12-Volt battery. To calculate the approximate power in Amps a 12Volt battery bank you need to know the current, or Amps required for powering the continuous AC load. A shortcut method is to divide

of the PRO 3000W Power Inverter is 3000 Watts

VDC. Add to the

load any DC appliances that may be powered by the battery bank.

the continuous AC load Wattage by 10.

. The current (Amps) is: 3000/10 or 300 Amps at 12

For example, the continuous load

MOUNTING THE INVERTER

Do not mount the power inverter under the hood of any vehicle. Choose a cool, dry, and well-ventilated area inside the vehicle as close to the battery as possible. Place the power inverter on a flat, secure surface. Make sure there are no wires, fuel lines or fluid tanks directly behind the wall or surface being drilled. When mounting, secure the power inverter in place using corrosion-resistant mounting hardware (not included). What you will need:

• Assess your mounting needs depending

on the inverter and type of surface you are mounting (i.e. wood or fiber glass)

• Gather the necessary tools depending

on the surface (i.e. drill or screwdriver)

• Determine size of mounting hardware.

Use only corrosive resistant screws (not included)

Mounting Instructions:

1. Make sure the inverter is OFF.

2. Check for wires, fuel lines or fluid tanks behind the wall or surface you plan to drill.

3. Position the power inverter horizontally when choosing the mounting location. If mounted on a wall

be sure the front of the inverter is facing out. Do not mount vertically to prevent debris or dust from falling into the power inverter.

4. Mark the locations of the mounting screws before drilling.

5. Remove the inverter and drill the (4) mounting holes.

6. Fasten the inverter to the mounting surface using corrosion-resistant screws (not included).
