CobraMarine™ M2200 Output Waveform
WARNING Power inverters contain components that may 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.
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).
Some very sensitive electronic equipment may not operate satisfactorily on “square
wave” or “modified sine wave.”
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
Ground Fault Circuit Interrupter (GFCI) Outlet
Certain chargers for small nickel cadmium batteries can be damaged if connected to
the CobraMarine™ M2200 Power Inverter. Two (2) particular types of equipment are
prone to this problem:
Test the GFCI periodically to make sure it is operating properly
(see page 16 for details).
1. Small battery-operated appliances such as flashlights,
Plug In Directly
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
Dangerous Voltages
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
Quick Evaluation Before Installation
To Check Your Inverter’s Performance Before Installation:
1. Turn the inverter Off (see page 15 for details).
•
This section provides you with basic information about the inverter and how
to check its performance before installation.
On/Off Switch to Off
Connect Terminals
Connect Power Source
On/Off Switch to On
Connect Test Load
Test GFCI Outlet
If the power source is a DC power supply,
switch it Off as well.
Be Sure to Have on Hand:
ꢀ A 12 volt DC power source (such as a vehicle battery).
Power Supply
2. Connect cables to Power Input Terminals
(see page 8 for details).
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.
3. Connect cables to Power Source
(see page 8 for details).
4. Check to make sure all connections are secure.
ꢀ A set of cables to connect the power source to the inverter (not included).
5. Turn the inverter On. If the power source is
a DC power supply, switch it On first.
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.
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 21 or Power
and Protection Indicators section on page 18.
#4 AWG stranded copper cable is recommended. It should be no longer than
1.5 meters (4 feet).
The end of the cable that connects to the inverter must have its insulation stripped

off for about ⁄2 inch (1.25 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.

Installation Requirements
Mounting
•
•
The inverter must be installed in an area that meets all of the following requirements:
To Mount Your Inverter:
1. Place the inverter on a flat surface with the mounting bracket against
the mounting surface.
A. Dry
Do not place in an area where water can drip or splash on the inverter.
Mounting Brackets
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 1 inch (3 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.
2. Mount to secure surface using mounting hardware that is corrosion
resistant (not included).
E. Close to Battery
Mounting Hardware
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.
The inverter can be mounted horizontally or vertically.
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.

Installation
Connecting Cables (not included)
Strip the Insulation
•
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.
1
Use only copper wire. Aluminum wire has about ⁄3 more resistance than copper
wire of the same size, plus it is difficult to make good, low-resistance connections
to aluminum wire.
We recommend #4 AWG copper cable (90°C insulation rating) as the minimum
size for connections between the battery and inverter.
3. Connect cables to the Power Input Terminals on right side panel of the inverter. The
red terminal is positive (+) and the black terminal is negative (-). Insert the bare ends
of the cables into the terminals and tighten the screws to clamp the wires safely.
Insert Bare Cables
Keep the cable length as short as possible, no more than 4 feet (1.5 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.
4. Connect cables to the power source:
a. Connect each cable from the Negative (Black) Terminal of inverter to the
Negative Terminal of the power source. Make a secure connection.
Turn On/Off Switch to Off
b. Connect each cable from the Positive (Red) Terminal 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
1
insulation about ⁄
2
inch (1.25 cm), exposing the bare copper conductor.
You might observe a spark when you make this connection,
since current can flow to charge capacitors in the inverter.

Installation
Installation
All power connections to your CobraMarine™ Power Inverter must be
Positive To Positive and Negative To Negative.
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.
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.
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.
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 2200 watts.
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.
CAUTION Loose connectors result in excessive voltage drop and may cause
overheated 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.).

Power Consumption
Ground Wiring
Installation
Installation
Power Consumption
Ground Wiring
•
•
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 amperes) or
ampere-hour capacity (a measure of how many amperes a battery can deliver
for a specified length of time).
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.
Example – Reserve capacity: a battery with a reserve capacity of 180 minutes
can deliver 25 amperes for 180 minutes before it is completely discharged.
Chassis Ground
Example – Ampere-hour capacity: a battery with an ampere-hour capacity of
100 ampere-hours can deliver 5 amperes 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.
In a Vehicle:
Connect the Chassis Ground to the chassis of the vehicle.
In a Boat:
Connect to the Boat Grounding System.
2. Estimate the time (in hours) that each piece of equipment will be running between
battery charging cycles.
In a Fixed Location:
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.
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.
Laptop
TV/VCR (up to 25")
Blender
300 Watts x 15 minutes
= 75 Watt-Hours
100 Watts x 2 hours
= 200 Watt-Hours
115 Watts x 3 hours
= 345 Watt-Hours
4. Divide the watt-hours by ten (10) to determine how many power supply’s (12 volt)
ampere-hours will be consumed.

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

Some states do not allow limitations on how long an implied warranty lasts and/or
do not allow the exclusion or limitation of incidental or consequential damages, so
the above limitations may not apply to you.
To protect the battery, if the unit needs to be restarted after low voltage protection,
the voltage of DC input should be above 12V.
For Products Purchased Outside the U.S.A.
To extend the life of the fan, it will stop when there is no load. The speed of the fan
increases as the load increases.
Please contact your local dealer for warranty information.
The unit is completely insulated in input and output for added safety.

Maintenance
4. Pack power inverter securely to prevent damage in transit. If possible,
use the original packing material.
•
Very little maintenance is required to keep the inverter operating properly. The exterior
of the unit should be cleaned periodically with a damp cloth to prevent accumulation of
dust and dirt. At the same time, tighten the screws on the DC input terminals. Be sure
vents and fans are free of dust or debris.
5. Ship prepaid and insured by way of a traceable carrier such as United
Parcel Service (UPS) or First Class Mail to avoid loss in transit to:
