Important Information

Important Information About Your New Whistler Inverter.

This manual will provide you with directions for the safe and efficient operation of your Whistler Inverter. Read the manual carefully before using your new Whistler inverter and keep the manual on file for future reference.

Notes:

Your Whistler inverter is designed to operate from a 12 volt power source only. Never attempt to connect your Whistler inverter to any other power source, including any AC power source.

•The length of the supplied cables is matched for the current needed by the inverter. Making this cable longer will make the inverter less efficient and may cause the cables to heat up.

•Do not attempt to lengthen the supplied power cables.

•110 volts can be lethal. Improper use of your Whistler inverter may result in property damage, personal injury or loss of life.

•Not reccommended for use with medical equip- ment. Check with the appliance manufacturer for compatibility with modified sine wave inverters. Some appliances may not work well, not at all or be damaged. For more information on compatibility issues, please visit our inverter FAQ page at www.whistlergroup.com.

INVERTER BASICS

Getting Started

Power equipment and appliances which operate with motors or tubes require an initial surge of power to get them up and running. This power surge is referred to as the "starting load" or "peak load." (By comparison, electrical devices such as standard light bulbs do not require a large starting load). Once the equipment or appliance has been powered up, it settles down to a slower pace and requires far less electrical power to operate. This lower power requirement is referred to as the "continuous load."

In order to ensure that the capacity of your Whistler inverter is sufficient to meet the required start up load, you must first determine the power consumption of the equipment or appliance you plan to operate.

Power consumption is rated either in wattage or in amperes, and information regarding the required "watts" or "amps" generally is stamped or printed on most appliances and equipment. If this information is not indicated on the appli- ance or equipment, check the owner’s manual. Contact the appliance or equipment manufacturer to determine if the device you are using (TV’s, battery re-charger, com- puter, etc.) is compatible with a modified sine wave.

If the power consumption is rated in amps, multiply the num- ber of amps by 110 (AC voltage) to determine the compara- ble wattage rating. Induction motors, as well as some televi- sions, may require 2 to 6 times their wattage rating to start up.
