Introduction
Important Safety Information
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 2500 watt inverter. Two particular types of equipment are prone to this problem:
Plug In Directly
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
Dangerous Voltages
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.
Introduction
Important Safety Information
Cobra 2500 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).

Introduction
Quick Evaluation
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).
Power Supply
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.
£ A set of 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 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.
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

Installation
Installation
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).
Requirements
CAUTION To avoid fire, do not cover or obstruct ventilation openings. Do not install inverter in a zero­clearance 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.
Installation
Mounting
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.
WARNING This unit is suitable for installation in negative ground applications only. Do not attempt to install to a positive ground application.
Mounting
To mount your inverter:
1. Place the inverter on a flat surface with the
mounting bracket against the mounting surface.
Mounting Brackets
2. Mount to secure surface using mounting hardware that is corrosion resistant (not included).
Mounting Hardware
The inverter can be mounted horizontally or vertically.

Installation
Connecting Cables Connecting Cables
Connecting Cables (not included)
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.
Use only copper wire. Aluminum wire has about one-third more resistance than copper wire of the same size, plus it is difficult to make good, low-resistance connections to aluminum wire.
We recommend two #4 AWG copper cables (90°C insulation rating) as the minimum size for connections between the battery and inverter.
Keep the cable length as short as possible, no more than four feet (one and one-half meters). This will keep the voltage drop to a minimum.
If the cable has too much voltage drop, the inverter may shut down when drawing higher currents because voltage at the inverter may drop below 10 volts. If you must use longer cables, choose thicker cables, such as #2 AWG, and trim the ends of the cable to fit the terminals.
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.
On/Off Switch to Off
Installation
Strip the Insulation
3. Connect cables to the Power Input Terminals on right side
panel of the inverter. The red terminals are positive (+) and the black terminals are negative (-). Insert the bare ends of the cables into the terminals and tighten the screws to clamp the wires safely.
Insert Bare Cables
4. Connect cables to the power source:
a. Connect each cable from the Negative (Black) Terminals
of inverter to the Negative Terminal of the power source. Make a secure connection.
b. Connect each cable from the Positive (Red) Terminals of
the inverter to the Positive Terminal of the power source (the battery’s main fuse or the battery selector switch, if you are using one). Make a secure connection.
Connect Cables
2. On the end of the cable that connects to the inverter, strip back the insulation about one-half inch (one and one-half cm), exposing the bare copper conductor.

Installation
Connecting Cables Connecting Cables
You might observe a spark when you make this connection, since current can flow to charge capacitors in the inverter.
All power connections to your Cobra inverter must be Positive
to Positive and Negative to Negative.
CAUTION Electrical installations must meet
local and national wiring codes, and should be performed by a qualified electrician.
CAUTION Do not connect the inverter and another AC source (such as a generator or utility power) to the AC wiring at the same time. The inverter will be damaged if its output is connected to AC voltage from another source. Damage can even occur if the inverter is switched off.
CAUTION Do not connect the inverter to an AC branch circuit that has high-power consumption loads. It will not operate electric heaters, air conditioners, stoves, and other electrical appliances that consume more than 2500 watts.
CAUTION Loose connectors result in excessive voltage drop and may cause over heated wires and melted insulation.
CAUTION Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and may permanently damage the unit. Such damage is not covered by the warranty.
CAUTION We recommend a main fuse in the battery’s positive cable to protect against DC wiring short circuits (external to the inverter). The fuse should be as close to the battery as possible. We recommend a Buss Fuse ANL-250 or equivalent. The specific fuse ampere rating should be sized to allow operation of all your DC powered equipment.
CAUTION Remove any jewelry (watch, ring, etc.). Be careful not to short circuit the battery with any metallic object (wrench, etc.).
Installation
WARNING If you are making a permanent AC connection to the inverter, make sure that the AC wiring steps are performed before any DC wiring is done. (DC hook-up energizes internal components, regardless of the position of the On/Off Switch). Working on AC connections in such a circumstance may result in an electric shock.
WARNING 115 volt AC power is potentially lethal. Do not work on AC wiring when it is connected to the inverter (even if it is switched off) unless the DC power source is physically disconnected from the inverter. Also, do not work on AC wiring if it is connected to another AC power source such as a generator or the utility line.
WARNING You may observe a spark when making the connection because current can flow to charge the capacitors in the inverter.
Do not make this connection in the presence of flammable fumes. Explosion or fire may
result. Thoroughly ventilate the battery compartment before making this connection.
NOTE If only one power source is used, connect both cables from the negative terminal of the inverter to the negative terminal of the power source. Then connect both cables from the positive terminals of the inverter to the positive terminal of the power source.

Power Consumption Ground Wiring
Power Consumption
For each piece of equipment you will be operating from the 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 – Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25 ampere for 180 minutes before it is completely discharged.
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 current draw is given, multiply the current draw by 115 to get the watt consumption.
2. Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles.
3. Calculate the total watt-hours of energy consumption (power x operating time) using the average power consumption and the total estimated running time (in hours). Power x Operating Time = Watt-Hours.

TV/VCR (up to 25")
Blender
Installation
Ground Wiring
There is a screw on the rear panel for Chassis Ground. This is to connect the chassis of the inverter to ground.
The Chassis Ground Screw must be connected to a grounding point, which will vary depending on where the unit is installed. Use a #8 AWG copper wire (preferably with green/yellow insulation) to connect the chassis ground screw to the grounding point.
Chassis Ground
In a vehicle: Connect the Chassis Ground to the chassis of the vehicle.
In a boat: Connect to the Boat Grounding System.
In a fixed location: Connect the Chassis Ground Screw to
earth ground by connecting to a ground rod (a metal rod pounded into the earth) or other proper service entrance ground.
50 watts x 2 hours = 100 watt-hours
115 watts x 3 hours = 345 watt-hours
300 watts x 15 minutes = 75 watt-hours
4. Divide the watt-hours by 10 to determine how many power supply’s (12 volt) ampere-hours will be consumed.

Operation
Power On and Off
Turning Your Inverter On or Off
Be sure to have your power inverter properly installed before attempting to turn the unit on (see installation page 6).
To turn the power inverter on:
1. If a DC power supply is being used as the power source, switch it on.
2. On the left side panel, switch the On/Off Switch to on.
On/Off Switch to On
The inverter is now ready to deliver AC power to your loads. If several loads are to be operated by the inverter, turn them on separately, after the inverter has been turned on. This will ensure that the inverter does not have to deliver the starting currents required for all the loads at once.
To turn the power inverter off:
1. On the left side panel, switch the On/Off Switch to off.
On/Off Switch to Off
Operation
Remote On/Off Switch
NOTE The On/Off Switch turns the control circuit in the inverter on and off. It does not disconnect power from the inverter.
When the switch is in the off position, the inverter draws no current from the battery. When it’s in the on position, but no power is being supplied to the load, the inverter draws less than 500 milliamperes from the battery. This is low current draw. It would take more than a week to discharge a 100 ampere-hour battery at this rate depending on the age of the battery.
Remote On /Off Switch (not included)
An optional Remote On/Off Switch (not included) can be connected to the Remote Jack allowing you to turn the Cobra power inverter on or off from a convenient location when the inverter is installed in an out of reach location.

Power and Protection
Operation
Power and Protection Indicators
The power and protection indicators include a green light, a red light, an alarm and a current meter.
Green Light
Power on – The green light should remain on steady.
Red Light and/or Alarm
Current overload – The red light will turn on momentarily, then the inverter will shutdown. The inverter will continue to check for appropriate current levels while trying to restart the load.
DC input voltage overload – The red light will turn on and the inverter will shutdown. The inverter will continue to check for appropriate voltage levels while trying to restart the load.
DC input voltage shortage – As a warning that the voltage is getting low, the internal alarm will sound. When the voltage is too low, the inverter will shutdown and the red light will turn on.The inverter will continue to check for appropriate voltage levels while trying to restart the load.
Temperature overload – The red light will turn on momentarily, then the inverter will shutdown. The inverter will continue to check for appropriate temperature levels and the red light will continue to blink while trying to restart the load.
No Plugs at 0%
One Plug at 40%
Indicators
NOTE A momentary sound of the internal alarm and/or flash of the red light is normal at start up.
Current Meter
The current meter indicates the current drawn from the battery. It will not indicate the current drawn by other loads also connected to the battery.
For long term operation, the current meter should remain in the middle of the bar graph.
Operation
Operating Limits
Operating Limits
Power Output
The inverter can deliver 2500 watts for about 60 minutes. The inverter must cool for 15 minutes before it can resume operation at 2500 watts. Note: The wattage rating applies to resistive loads.
The inverter will operate most AC loads within its power rating. Some induction motors used in freezers, pumps, and other motor-operated equipment require very high surge currents to start. The inverter may not be able to start some of these motors even though their rated current draw is within the inverter’s limits. The inverter will normally start single phase induction motors rated at one-half HP or less.
Input Voltage
The inverter will operate from input voltage ranging from 10 volts to 15 volts. Optimum performance will occur when the voltage is between 12 volts and 14 volts. If the voltage drops below 10.5V+/-0.3V, an audible low battery warning will sound. The inverter will shut down if the input voltage drops below 9.5V+/-0.3V. This protects the battery from being over-discharged. It will restart when the input voltage exceeds 12V+/-0.3V.
The inverter will also shut down if the input voltage exceeds
15.75V+/-0.75V. This protects the inverter against excessive input voltage. Although the inverter has protection against over-voltage, it may still be damaged if the input voltage were to exceed 16 volts.
