Nothing comes close to a Cobra

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.

All power connections to your CobraMarine
™
Power 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 2200 watts.
CAUTION Loose connectors result in excessive voltage drop and may cause
overheated 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.).
