Introduction Caution: Rechargeable Appliances To make the most of this inverter, it must be installed and used properly. Please read the installation and operating instructions carefully before installing and using it. Special attention must be paid to the CAUTION and WARNING statements in the manual. CAUTION statements specify conditions which could cause damage to the unit or other equipment. WARNING statements identify conditions that could result in personal injury or loss of life.
Quick Checkout Quick Checkout Quick Checkout This section provides you with basic information about the inverter and how to check its performance before installation.
Connection Connection 2. Connect the cables to the power input terminals on right side panel of the inverter. The red terminal is positive (+) and the black terminal is negative (-). Insert the bare ends of the cables into the terminals and tighten the screws to clamp the wires safely. Connection continued CAUTION: Loosely tightened connectors can cause excessive voltage drops and may result in overheated wires and melted insulation.
Installation Mounting/Cables Installation CAUTION: To avoid fire, do not cover or obstruct ventilation openings. Do not install inverter in a zero-clearance compartment. Overheating may result. WARNING: This unit contains components which can produce arcs or sparks. To prevent fire or explosion, do not install in compartments containing a battery or flammable materials, or in a location which requires ignition protected equipment.
Cables Ground Wiring If the cable has too much voltage drop, the inverter may shut down when drawing higher currents because voltage at the inverter may drop below 10 volts. If you must use longer cables choose thicker cables, such as #2 AWG, and trim the ends of the cable to fit the terminals. Strip back the insulation about 1/2 inch (1.25cm) on the end of the cable that connects to the inverter, exposing the bare cooper conductor.
DC Wiring DC Wiring DC Wiring DC Wiring WARNING: 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. 1. Be sure the ON/OFF switch on the inverter is in the OFF position. CAUTION: Loosely tightened connectors result in excessive voltage drop and may cause over heated wires and melted insulation.
Controls and Indicators ON/OFF Switch Controls and Indicators Turns the control circuit in the inverter On and Off. It does not disconnect power from the inverter. When the switch is in the Off position, the inverter draws no current from the battery.When it’s in the On position, but no power is being supplied to the load, the inverter draws less than 500 milliamperes from the battery. This is low current draw. It would take more than a week to discharge a 100 amperehour battery at this rate.
Troubleshooting Guide Troubleshooting Guide Problem /Symptom Possible Causes Solution Problem /Symptom Possible Causes Solution Low output voltage on voltmeter (96 VAC to 104 VAC) Using average reading Use true RMS meter reading Poor DC wiring, poor battery condition Low output voltage and current indicator in red zone Overload Reduce the load Low battery alarm on all the time, voltage indicator below 11 V Use proper cable, make solid connections, use new battery Thermal shutdown No output volt
Power Consumption Specifications For each piece of equipment you will be operating from the inverter you must determine the battery’s capacity (how long the battery can deliver a specific amount of current—in automotive batteries, usually 25 amperes). For example, a battery with a reserve capacity of 180 minutes can deliver 25 amperes for 180 minutes before it is completely discharged. Calculate the total watt-hours of energy consumption (power x operating time).
Limited Three Year Warranty COBRA ELECTRONICS CORPORATION warrants that its COBRA Power Inverter, and the component parts thereof, will be free of defects in material and workmanship for a period of 3 years from the date of consumer purchase. This warranty may be enforced by the first consumer purchaser, provided that the product is utilized within the U.S.A.
