Nothing comes close to a Cobra

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.
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 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
metallic object (wrench, etc.).
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.
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.
NOTE If only one power source is used, connect both
cables from the negative terminal of the inverter to the
negative terminal of the power source. Then connect
both cables from the positive terminals of the inverter
to the positive terminal of the power source.
