with the NVC450D, carefully attach them to the vehicle’s battery terminals, being very careful not to let the red clip lead  
touch any metal other than the battery terminal, and also making sure to observe correct polarity (red to red, black to  
black).  
2.  
Lenmar’s N-Verter is an electronic device that converts low voltage DC (direct current) electricity from a battery to  
110/120VAC (alternating current) standard household power.The AC output of this product is a modified sine wave with  
a voltage of 110/120 volts. With your Lenmar N-Verter you can power your laptops, computerized games, cell phones,  
camcorders, power tools, reading lamps, fans, and more.  
DANGER! – Do not create a short circuit when working with your vehicle’s power system. Damage to your vehicle’s  
internal electronics, explosion of the battery and personal injury may occur. NEVER test for the presence of power by  
“sparkingor shorting two wires together.  
Important: Before using your N-Verter, read and understand this owner’s guide. Save these instructions–this owner’s  
guide contains important safety instructions.  
3. After the power connection is made, if the unit’s status LED is not already green, momentarily press the power switch on  
the unit and the LED will light up and turn quickly from red to green if power is present. The green LED indicates the  
N-Verter is powered on and running with power available at the AC outlet(s).  
Safe Operating Guidelines  
WARNING! Shock hazard The N-Verter generates the same AC power as a normal household wall outlet.  
Operate only in ventilated area away from flammables, flames and accumulating dangerous or explosive fumes  
Do not expose unit to water, rain or snow  
Note: Many vehicles remove power from the cigarette lighter outlet when the ignition key is turned off!  
Always turn OFF unit by removing it from the DC cigarette lighter outlet when not in use  
Avoid exposure to direct sunlight and extreme temperatures (60-80°F or 15-25°C)  
Plug an AC device into the three-prong AC receptacle and then turn it on. Ensure your device draws less than the  
continuous power rating of your N-Verter. The N-Verter’s internal cooling fan will come on for loads over 80W. To avoid  
discharging the battery, always disconnect the N-Verter from power when not in use.  
4.  
Do not insert foreign objects into the outlet.  
Do not open the unit: no replaceable parts inside  
Consult motor vehicle’s manual to determine cigarette lighter socket’s maximum power rating and fuse rating before  
attempting use in vehicle.  
Using the Digital Display (NVC450D only)  
This model has a digital display which will give detailed information about the operating conditions of the unit such as  
the input voltage of the N-Verter, the output wattage being demanded and if an error condition exists, the display will  
show an error code that will specifically tell the problem that was encountered. When the status LED is green, the digital  
display will continuously alternate between showing the input voltage and showing the output power level. When  
showing the voltage the display will indicate “-U-“ followed by the measured voltage. Next, the display will show the  
power output by indicating-P-“ followed by the estimated power output,in Watts,from 30W to the maximum 450Watts.  
Wattages below 30 Watts will indicate as0.If the device fluctuates in the amount of power that it uses over a given time,  
then the displayed power output will vary with each cycle as well.  
Unit will not and should not operate heat-generating appliances such as hair-dryers, microwave ovens, electric blankets,  
toasters, etc.  
Compatible only with vehicles that have 12VDC Negative Ground electrical systems  
Failure to follow the above may result in personal injury or damage to the N-Verter.  
Special Features:  
NVC450D – A versatile built-in digital display shows incoming voltage, output power level, and error codes so there is  
no guessing required as to any problems that may occur. Also, comes with both cigarette lighter adapter cable for  
convenience and usage below 300W,as well as clip-leads to attach direct to the battery terminals for higher power usage  
from 300W up to the maximum.  
If the status LED is red,an error condition exists and a corresponding error code will appear on the digital display.See the  
Troubleshooting section for the meanings of the error codes.
