Introduction  
Caution: Rechargeable Appliances  
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 state-  
ments identify conditions that could result in  
personal injury or loss of life.  
Caution: Rechargeable Appliances  
Certain rechargers for small nickel cadmium bat-  
teries can be damaged if connected to the Cobra  
2000W inverter. Two particular types of equip-  
ment 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 charges have a  
WARNING label stating that dangerous volt-  
ages are present at the battery terminals.  
Cobra 2000W Output Waveform  
The output waveform is referred to as “square  
wave” or “modified sine wave.” It is a stepped  
waveform designed to have characteristics simi-  
lar to the sine wave shape of utility power. A  
waveform of this nature is suitable for most AC  
loads (including linear and switching power sup-  
pliers used in electronic equipment, transformers  
and motors).  
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 that 30  
volts) the inverter will have no problem  
powering it safely.

This section provides you with basic information  
about the inverter and how to check its perfor-  
mance before installation. Be sure to have the fol-  
lowing on hand:

500 w  
# 16 AWG copper  
# 12 AWG copper  
# 8 AWG copper  
A 12 volt DC power source (such as a vehicle battery)  
A set of cables to connect the power source to the inverter  
The end of the cable that connects to the invert-  
er must have its insulation stripped off for about  
1/2 inch (1.25cm) back from the end, exposing  
the bare copper.  
A test load that can be plugged into the AC receptacle  
on the inverter  
Power Source  
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.  
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.  
Cables (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 it is drawing  
current from the power source.  
Connection  
Connection  
1. Turn the ON/OFF switch on the inverter to  
the OFF position.  
If the cable suffers an excessive voltage drop, the  
inverter may shut down when drawing higher cur-  
rents because the voltage at the inverter dropped  
below 10 volts.  
If the power source is a DC power supply,  
switch it off as well.  
#4 AWG stranded copper cable is recommended. It  
should be no longer than 1.5 meters (4 ft.). For  
short term testing at a low power level, the  
following is recommended:

Connection  
Connection  
2. Connect both sets of 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.  
5. If a DC power supply is being used as the  
power source, switch it On. Turn the ON/OFF  
switch on the inverter to the On position.  
Check the meters on the left side panel. The  
voltage should indicate between 11 and 14  
volts, depending on the voltage of the power  
source.  
Connection

CAUTION: Loosely tightened  
connectors can cause exces-  
sive voltage drops and may  
result in overheated wires and  
melted insulation.  
WARNING: You may observe a  
spark when making the con-  
nection because current can  
flow to charge the capacitors  
in the inverter. Do not make  
this connection in the pres-  
ence of flammable fumes.  
Explosion or fire may result.  
CAUTION: A reverse polarity  
connection (positive to nega-  
tive) will blow the fuse in the  
inverter and may permanently  
damage the unit.  
3. Connect each cable from the negative (black)  
terminal of inverter to the negative terminal of  
the power source. Make a secure connection.  
6. Turn the inverter’s ON/OFF switch to the Off  
position. The indicator lights may blink and  
the internal alarm may sound momentarily.  
This is normal. Plug the test load into the AC  
receptacle on the left side panel of the invert-  
er. Leave the test load switched Off.  
CAUTION: Remove any jewel-  
ry (watch, ring etc.). Be careful  
not to short circuit the battery  
with any metallic object  
(wrench, etc.).  
All power connections to your Cobra inverter  
must be positive to positive and negative to  
negative.  
4. Connect the cables from the positive (red) ter-  
minals of the inverter to the positive terminal of  
the power source. Make a secure connection.  
7. Switch the inverter’s ON/OFF switch to the On  
position and turn the test load On. The inverter  
should supply power to the load.  
NOTE: If only one power  
source is used, connect both  
cables from the negative ter-  
minal of the inverter to the  
negative terminal of the power  
source. Then connect both  
cables from the positive termi-  
nals of the inverter to the posi-  
tive terminal of the power  
source.  
If it does not, please consult the troubleshoot-  
ing section in this manual.

Installation  
Mounting/Cables  
Installation  
The inverter must be installed in an area that  
meets all of the following requirements:  
Mounting  
Installation  
Mounting  
Mount the inverter on a flat surface placing the  
mounting bracket on the bottom. Mounting  
hardware should be corrosion resistant and at  
least #10 or larger. The inverter can be mounted  
horizontally or vertically.  
CAUTION: To avoid fire, do not  
cover or obstruct ventilation  
openings. Do not install invert-  
er in a zero-clearance com-  
partment. 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.  
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.  
Cables (included)  
WARNING: This unit contains  
components which can pro-  
duce arcs or sparks. To prevent  
fire or explosion, do not install  
in compartments containing a  
battery or flammable materi-  
als, or in a location which  
requires ignition protected  
equipment.  
Power wire and wiring is very important to the  
performance of the inverter. Because the inverter  
has a low voltage, high current input, low resis-  
tance wiring is essential between the battery and  
inverter. This is so it can deliver the maximum  
amount of energy to the load.  
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.  
C. Ventilate- Allow at least 1 inch (3cm) of clear-  
ance 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 compart-  
ment that contains flammable liquids such  
as gasoline.  
Use only copper wire. Aluminum wire has about  
1/3 more resistance than copper wire of the  
same size plus it is difficult to make good, low-  
resistance connections to aluminum wire.  
E. Close to battery- Install unit as close to bat-  
tery 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).  
We recommend two #4 copper cables (90° C  
insulation rating) as the minimum size for con-  
nections between the battery and inverter.  
WARNING: 115 Volt AC power is  
potentially lethal. Do not work  
on AC wiring when it is connect-  
ed to the inverter (even if it is  
switched off) unless the DC  
power source is physically dis-  
connected form the inverter.  
Also, do not work on AC wiring  
if it is connected to another AC  
power source such as a genera-  
tor or the utility line.  
Keep the cable length as short as possible, no  
more than 4 ft. (1.5 meters). This will keep the  
voltage drop to a minimum.

Cables  
Ground Wiring  
CAUTION: Electrical installa-  
tions must meet local and  
national wiring codes, and  
should be performed by a  
qualified electrician.  
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 termi-  
nals.  
Ground  
Wiring  
Warning: Do not operate the  
inverter without connecting it  
to ground. Electrical shock  
hazard may result.  
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 con-  
nected to AC voltage from  
another source. Damage can  
even occur if the inverter is  
switched Off.  
Ground Wiring  
There is a screw on the rear panel labeled Chassis  
Ground. This is to connect the chassis of the  
inverter to ground. The ground terminal in the AC  
outlet on the right side panel of the inverter is  
connected to the chassis.  
Strip back the insulation about 1/2 inch (1.25cm),  
on the end of the cable that connects to the  
inverter, exposing the bare cooper conductor.  
The other end of the cable that connects to bat-  
tery must be terminated with a battery terminal  
that clamps to the post on the  
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 ground-  
ing point.

WARNING: Do not make this  
connection in the presence of  
flammable fumes. Explosion or  
fire may result. Thoroughly  
ventilate the battery compart-  
ment before making this con-  
nection.  
DC Wiring  
DC Wiring  
1. Be sure the ON/OFF switch on the inverter is  
in the OFF position.  
CAUTION: Loosely tightened  
connectors result in excessive  
voltage drop and may cause  
over heated wires and melted  
insulation.  
5. Connect the cable from the positive terminal  
of the inverter to the positive terminal of the  
battery’s main fuse, or to the battery selector  
switch, if you are using one. Make a secure  
connection.  
CAUTION: Reverse polarity  
connections (positive to nega-  
tive) will blow internal fuses in  
the inverter and may perma-  
nently damage the unit. Such  
damage is not covered by the  
warranty.  
2. Connect the cables to the power input termi-  
nals on the rear panel of the inverter. The red  
terminals are positive(+) and the black termi-  
nals are negative (-). Insert the bare ends of  
the cables into the terminals and tighten the  
screws to clamp the wires securely.  
You might observe a spark when you make this  
connection since current can flow to charge  
capacitors in the inverter.  
Operation.  
CAUTION: We recommend a  
main fuse in the battery’s posi-  
tive cable to protect against  
DC wiring short circuits (exter-  
nal to the inverter). The fuse  
should be as close to the bat-  
tery as possible. We recom-  
mend a Buss Fuse ANL-250 or  
equivalent. The specific fuse  
ampere rating should be sized  
to allow operation of all your  
DC powered equipment.  
Turn the inverter On by using the ON/OFF switch  
on the left side panel .  
3. Connect the cable from the negative terminal  
of the inverter to the negative terminal of the  
battery. Make a secure connection.  
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.  
4. Double check that the cable you just installed  
connects the negative terminal of the invert-  
er to the negative terminal of the battery.  
Power connections to the inverter must be  
positive to positive and negative to negative.

power rating. Some induction motors used in freez-  
ers, pumps, and other motor-operated equipment  
require very high surge currents to start.The invert-  
er 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 sin-  
gle phase induction motors rated at 1/2 HP or less  
Input Voltage  
Input Voltage  
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.  
The inverter will operate from input voltage rang-  
ing from 10 volts to 15 volts. Optimum perfor-  
mance will occur when the voltage is between 12  
volts and 14 volts. If the voltage drops below  
10.5+/-0.3V volts, an audible low battery warning  
will sound. The inverter will shut down if the  
input voltage drops below 9.5V+/-0.3V volts. This  
protects the battery from being over-discharged.  
It will restart when the input voltage exceeds  
10.5V+/-0.3V volts.  
Don’t worry about excessive drain on the battery if  
you leave the inverter switched On for a few days.  
However, do switch it off if you are not planning be  
recharge the battery within a week or so.

Limits  
Power Output  
The inverter will deliver 2000 watts continuously. It  
can deliver 2400 watts for about 30 minutes.The  
inverter must cool for 15 minutes before it can  
resume operation at 2000 watts. Note:The wattage  
rating applies to resistive loads.  
The inverter will also shut down if the input volt-  
age falls to 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 exceeds 16 volts.
