Introduction
Important Safety Information
WARNING Power inverters contain components that can produce arcs or sparks. To prevent fire or explosion, do not install the inverter in areas or compartments containing batteries or flammable materials or in locations that require ignition- protected equipment.
WARNING To reduce the risk of fire, do not cover or obstruct the ventilation openings. Do not install
inverter in zero-clearance compartment.
Warning: Wash Hands After Handling Power Cord
The power cord on this product contains lead, a chemical known in the state of California to cause birth defects or Caution:other reproduRechargeabletive harm. Appliances
Certain chargers for small nickel cadmium batteries can be damaged if connected to the Cobra 400 watt inverter. Two particular types of equipment are prone to this problem:

Before Installation
Cobra 400 Watt Output Waveform
Some very sensitive electronic equipment may not operate satisfactory on “square wave” or “modified sine wave.” The output waveform is referred to as “square wave” or “modified sine wave.” It is a stepped waveform designed to have characteristics similar to the sine wave shape of utility power. A waveform of this nature is suitable for most AC
loads (including linear and switching power suppliers used | ||
in electronic equipment, transformers and motors). | • | |

This section provides you with basic information about the inverter and how to check its performance before installation.
Be sure to have on hand:
≤A 12 volt DC power source (such as a vehicle battery).
Power Supply | The power source must provide |
| between 11 and 15 volts DC and |
| be able to supply enough current to |
| run the test load. As a rough guide, |
Plug In Directly
Dangerous Voltages
1.Small
night lights that can be plugged directly into an AC receptacle to recharge.
2.Certain battery chargers for battery packs used in hand power tools. These chargers have a WARNING label stating that dangerous voltages are present at the battery terminals.
divide the wattage of the test load by |
10 to get the current (in amperes) |
the power source must deliver. |
≤ The provided two foot cigarette lighter cable and |

Only use the cables provided with your inverter.
The cigarette lighter cable is suitable for operating the inverter at loads up to 150 watts. Connect by securely inserting the plug into the cigarette lighter socket.
Cig. Lighter Cable | 12 Gauge Cable |
This problem does not occur with the vast majority of battery operated equipment. Most use a separate charger or transformer that is plugged into the AC receptacle and produces a low voltage output. If the label on the AC adapter or charger states that it produces a low voltage AC or DC output (less than 30 volts), the inverter will have no problem powering the adapter safely.
CAUTION Do not use the cigarette lighter cable for loads higher than 150 watts. When connecting loads larger than 150 watts, please connect the inverter directly to the battery.
