Quick Evaluation Before Installation

Important Safety Information

Introduction

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 other reproductive harm.

Caution: Rechargeable Appliances

Certain chargers for small nickel cadmium batteries can be damaged if connected to the Cobra 800 watt inverter. Two particular types of equipment are prone to this problem:

Introduction

Cobra 800 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.

≤A 12 volt DC power source (such as a vehicle battery).Be Sure to Have on Hand:

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 battery-operated appliances such as flashlights, razors, and 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 direct-to-battery 12 gauge cable.
Cable	Only use the cable provided with
	your inverter.

≤A test load that can be plugged into the AC receptacle on the inverter for short term testing at a low power level.

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.
