Installation

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 connectionin the presenceof flammablefumes. 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) Terminalof inverter to the NegativeTerminal 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.

Youmight observea spark when you make this connection since currentcan flow to charge capacitorsin the inverter.

All power connections to your Cobra inverter must be Positiveto Positive and Negativeto Negative.

Installation

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 branchcircuitthat has high-powerconsumptionloads. It will not operate electric heaters, air conditioners, stoves,and other electricalappliancesthat consume more than 400 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 external fuse in the inverter 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 115 volt AC power is potentiallylethal. 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 physicallydisconnectedfrom 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 connectionbecause current can flow to charge the capacitorsin the inverter.Do not make this connectionin the presence of flammable fumes. Explosion or fire may result. Thoroughlyventilate the battery compartmentbefore making this connection.
