INTRODUCTION

Dear Whistler Owner,

For many of us, a vehicle is more than just transportation. It can be a mobile office, communications or entertainment center, or simply an expression of our personality. Whistler products are designed to make the time you spend in your vehicle more productive, more fulfilling, safer, or just simply more fun. Our mission is to provide products that improve your driving experience.

Whistler offers a complete line of DC to AC inverters ranging in capacity from 140 Watts to 2750 Watts. These inverters offer advanced technology, dependable operation and will provide years of reliable service when used in accordance with our operating instructions.

Your new Whistler GO AC power inverter allows you to run most AC appliances right from your car, boat or RV. They’re great for weekend use and life on the road. They’re also great for power outages!

To fully acquaint yourself with the operation of the Whistler

PP750AC we recommend reading this entire manual.

Sincerely,

THE WHISTLER GROUP

We’re Driving Technology

A Word About WHISTLER GO AC™ Inverters.

Whistler inverters convert low voltage, direct current (DC) to 110 volt alternating household current (AC). The AC output is called “modified sine wave”. See “Technical Operating Principles” section for more information. Depending on the model and its rated capacity, Whistler inverters draw power either from standard 12 volt automobile and marine batteries or from portable high power 12 volt sources.

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 GO-AC 750 Watt 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.

•Check with the appliance manufacturer for compatibility with modified sine wave inverters. Some appliances may not work well, not at all or be damaged. This is especially true for medical equipment.

For more information on compatibility issues, please visit our inverter FAQ page at www.whistlergroup.com/faqinverters.asp

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 appliance 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, computer, etc.) is compatible with a modified sine wave.

If the power consumption is rated in amps, multiply the number of amps by 110 (AC voltage) to determine the comparable wattage rating. As a general rule, you can determine the required start up load by multiplying the wattage rating by 10.

INVERTER BASICS

Don’t Push It.

Although your Whistler GO AC inverter has the capacity to provide power output (excess current) equal to approximately two times its rated wattage capacity for a very brief period, it is designed to operate equipment and appliances with start up load wattage ratings no higher than its own maximum continuous wattage rating.

For example, the 750 model has a maximum continuous rating of 750 watts. Although this model has the capacity to briefly provide up to 1500 watts of power (that is, excess current), it is designed to operate equipment and appliances with start up load requirements of 750 watts or less.

Consequently, if the start up load rating of your equipment or appliance is the same or approximately the same as the maximum continuous rating of the inverter, the inverter will attempt to start loads above the continuous rating for up to 10 seconds.

To determine whether your inverter will operate a particular piece of equipment or appliance, run a test. The inverter is designed to shut down automatically in the event of a power overload. Testing appliances and equipment with start up load ratings comparable to your inverter wattage rating will not damage it.

INVERTER BASICS

If a piece of equipment or an appliance will not operate, first confirm that the inverter has been properly connected to the 12 volt power source (See "Making The Connection"). If all connections have been properly made, turn the inverter rocker switch ON (l), OFF (O) and ON (l) again in quick succession. If this procedure is unsuccessful, it is likely that the inverter does not have the required start up capacity to operate the equipment or appliance in question.

Note:

•Most heat generating appliances require start up loads in excess of 1000 watts and the PP750AC inverter will not operate such appliances as coffee makers, irons, hair dryers or heaters.
