one-half cm), exposing the bare copper conductor.

3.Connect cables to the Power Input Terminalson 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) Terminalsof inverter to the NegativeTerminal of the power source. Make a secure connection.

b.Connect each cable from the Positive(Red) Terminalsof the inverter to the PositiveTerminal of the power source (the battery’s main fuse or the battery selector switch, if you are using one). Make a secure connection.

Installation

Youmightobservea sparkwhen 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.

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. 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
