Installation
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.
Connect Power Source
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
CAUTION Loose connectors result in excessive voltage drop and may cause over heated wires and melted insulation.

Installation
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 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 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.
