Notice
Caution
Warning
Certain chargers for small nickel cadmium batteries
can be damaged if connected to the Cobra 1500 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.

the power source must deliver.
£ 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 it is 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.

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.
Warning
Caution
Notice
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.
Warranty
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
Notesthe battery. It is better and cheaper to run longer
AC wires than longer DC wires (cables).
Warning
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.

connects to the inverter,
strip back the insulation about one-half inch (one and
one-half cm), exposing the bare copper conductor.
•
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 deliverNotice
the maximum
amount
of energy to the load.
Warning
Caution
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 #4 AWG copper cable (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 a 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.

Notes
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

Caution
WARNING If you are making a permanent AC
connection to the inverter, make sure that the AC
wiring

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.
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.

Notes
•
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
capacityCaution
(a measure
of how many amperes a
Warning
Notice
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.
100 watts x 2 hours
= 200 watt-hours

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.

Notes
All protection is automatically recovered.
To protect the battery, if the unit needs to be restarted
after low voltage protection, the voltage of DC input
should be above 12V.
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.
The unit is completely insulated in input and output for
added safety.
