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.
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).
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:
1. Small battery-operated appliances
Plug In Directly
such as flashlights, razors, and
night lights that can be plugged
directly into an AC receptacle to
recharge.
2.
Certain battery chargers for
Dangerous Voltages
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.

Quick Evaluation
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.

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 18
or power and protection indicators
section on page 16.

Mounting
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.
SafeBrackets
Mounting
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).
Mounting Hardware
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.

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.
2. Mount to secure surface using mounting hardware
that is corrosion resistant (not included).

Installation
Connecting Cables

Strip the Insulation 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
Insert Bare Cables
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.
Connect Cables
The inverter can be mounted horizontally or vertically.
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.
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.
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.
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.
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.
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

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.
Chassis Ground
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.

•
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
On/Off
Switch to –
OnReserve 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
On/Off
Switch to the
Off 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.
4. Divide the watt-hours by 10 to determine how many
power supply’s (12 volt) ampere-hours will be consumed.
•
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.
14 English
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.

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.
Operation
Operating Limits
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 amperehour battery at this rate depending on the age of
the battery.
Remote On /Off Switch (not included)
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.
•
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.
