2. Connect cable 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 ends of the cables onto the terminals
and tighten the screws to clamp the cables safely.
3. Connect cable to your vehicle’s cigarette lighter socket.
NOTE If the inverter is to be used at levels above
150 watts for extended periods of time, a direct
connection to the battery is recommended. Do
not use the cigarette cord for loads higher than
150 watts. Please contact your local dealer or
customer assistance for the proper cord for
direct to battery connections.
CAUTION Reverse polarity connections (positive
to negative) will blow inverter fuses and may
permanently damage the unit. Such damage
is not covered by the warranty.
CAUTION Remove any jewelry (watch, ring, etc.).
Be careful not to short circuit the battery with any
metallic object (wrench, etc.).
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.
3. Connect cable to the power source:
a. Connect the cable from the Negative (Black)
Terminal of inverter to the Negative Terminal
of the power source. Make a secure connection.
b. Connect the 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.
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.
