To reset the low voltage alarm on the Cobra Pro 3000W to the default 11.5 Volts setting:

1. Turn the power inverter on.
2. Press and hold the POWER button for 5 seconds or until the Input Voltage LED turns blue.

This action sets the Low Voltage Alarm back to the default 11.5 Volts.

Page 3: Introduction
HOW YOUR POWER INVERTER WORKS The Cobra PRO Power Inverter is a power conversion device that is designed and built to operate from low Voltage DC (Direct Current) power from your vehicle battery and converts it to standard 115 Volt AC (Alternating Current) power like you have in your home.

Page 8: Important Product/Safety Information
IMPORTANT PRODUCT /SAFETY INFORMATION Before installing and using your Cobra power inverter, please read these general precautions and warnings. Caution and Warning Statements 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.
Page 9: Pentagon Protection
AC loads (including linear and switching power suppliers used in electronic equipment, transformers and motors). PENTAGON PROTECTION® Cobra power inverters provide five levels of protection: 1. Over-Temperature: Auto-shut off will occur when the safe operating temperature has been exceeded.
Page 10: Getting Started
GETTING STARTED This section provides you with the basic information about the inverter and a few tips before installation. To get started, you will need: 1. A 12 Volt DC battery (i.e. vehicle battery). In order to understand how much current your battery must deliver, divide the number of Watts from your AC appliance or device by 10.
Page 11: Mounting The Inverter
Multiply: AC AMPS X 110 (AC Voltage) = WATTS. This formula yields a close approximation of the continuous load of your appliance. Multiply: WATTS X 2 = Starting load for most appliances, tools and devices. This formula yields a close approximation of the starting load for most appliances.
Page 12: Installation Requirements
INSTALLATION REQUIREMENTS The inverter must be installed in an area that meets all of the following requirements Dry - Do not place in an area where water can drip or splash on the inverter. Cool - Ambient air temperature should be between 30°F and 105°F (0°C and 40°C). The cooler the better.

PRO 1500W INSTALLATION INSTRUCTIONS: These instructions are specific for Negative Ground 12 Volt Systems. In a Negative Ground System, the negative terminal (Black) is connected to the chassis or engine housing. CAUTION: If you are not familiar with 12 Volt high current wiring, please contact a professional installer for assistance.
Page 14 Thoroughly ventilate the battery compartment before making this connection. All power connections to your Cobra inverter must be Positive to Positive and Negative to Negative.

Page 19: Turning Your Inverter On And Off
TURNING YOUR POWER INVERTER ON AND OFF Be sure to have your power inverter properly mounted and installed before attempting to turn it on (see page 11). PRO1500W/2500W POWER INVERTER BASIC OPERATION Press the POWER button to turn on your inverter. When powered on the Input Voltage LED is green.
Page 20: Changing The Low Voltage Alarm Setting
From the factory the inverter defaults to a 11.5 Volt Low Voltage Alarm setting for professional trucks. If using a Cobra Pro Power Inverter with other vehicle types such as a car, van or RV, run time can be extended by changing the default Low Voltage Alarm to the alternate setting at 10.5 Volts.
Page 21: Cobra Remote On/Off Controller With Fast Charge Usb
COBRA REMOTE ON/OFF CONTROLLER WITH FAST CHARGE USB The Cobra Remote On/Off Controller with Fast Charge USB is included with the Cobra PRO 3000W Power Inverter. All PRO Inverters come equipped with an RJ-45 jack labeled "REMOTE" for compatibility with the Cobra Remote On/Off Controller with Fast Charge USB to allow you to conveniently turn the inverter ON and OFF from anywhere inside your vehicle as well fast charge your devices at the same time.
Page 22: Operating Indicators
OPERATING INDICATORS Indicators on the power inverter show the unit’s power status and alarms for conditions that could cause it to shut down. Power on – The Voltage Input and Power Output indicators automatically toggle between input and output values at three-second intervals. The three LEDs indicate the mode the meter is in and the three digits indicate the voltage or power value.
Page 23: Operating Limits
OPERATING LIMITS Power Output Your PRO Series power inverter can operate on its full rated output for about 60 minutes. The inverter must cool for 15 minutes before it can resume operation at maximum output. The inverter will operate most AC loads within its power rating. Some induction motors used in freezers, pumps, and other motor-operated equipment require very high surge currents to start.
