one-half cm), exposing the bare copper conductor.
3. Connect cables to the Power InputTerminals 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.
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.

since current can flow to charge capacitorsin the inverter.
All power connections to your Cobra inverter must be
Positive to Positive and Negativeto 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
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.
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 permanentlydamagethe unit. Suchdamage
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
