To Connect Your Inverter to an EmPower Port Onboard an Aircraft
1.On the end of your Inverter power cable locate the Cigarette Lighter/Vehicle Power Adapter. Push down on the tab, and pull the cigarette plug apart from the
2.Find the
3.Ensure that the ON/OFF Switch located on the side of your Inverter is in the ON position. Your Inverter’s LED will glow when the Inverter is properly connected to the DC source.
Note: Only 75W of continuous power will be available from an Empower port. This is for your and the other passenger’s safety. If your device requires more than 75W of power the device may not work onboard an aircraft. Some notebooks requiring more than 75W may still function, but switch between “charging” and “battery” and suffer from a decrease in performance.
Preventing Overheating
1.Your Inverter needs to have the best possible air flow around it while operating. Note that the air flows into the back (intake) vents located near your Inverter’s power cable and exits through vents on the top of the Inverter next to the AC receptacle. Do not restrict the airflow as your Inverter may overheat.
2.Do not operate your Inverter near a heat source, heat vent, or in direct sunlight.
3.Ambient air temperature should be between 23 and 122° F.
Automatic Overheating Shutdown
If your Inverter’s internal temperature rises above 140° F (60° C) the Inverter will automatically shut itself off. To resume operating your Inverter once it has shutdown please remove the cigarette plug adapter from the DC power source and wait at least 15 min- utes before reinserting the cigarette plug adapter.
Starting and Running Your Vehicle’s Engine
•Your Inverter may be used with or without your vehicle’s engine running. However, your Inverter may momentarily stop oper- ating while your vehicle’s engine is starting as the battery voltage can drop substantially during cranking.
•Your Inverter draws less than 0.2 Amps from your vehicle’s battery when itis not supplying power to a load. Therefore, in most instances, your Inverter can be left connected to your vehicle’s DC power source when not in use since it draws so little current. However, if your vehicle is to remain unused for more than one day, disconnect your Inverter from your vehicle’s DC power source. Kensington recommends turning your Inverter OFF when not in use with the switch located on the side of the Inverter. The LED located on the top of your Inverter will not glow when the Inverter is successfully turned OFF.
•Depending on variables such as battery condition, device being operated, even weather, an automotive battery can be dis- charged after 2 to 8 hours of use. Users should either monitor voltage or start the vehicle every hour to recharge the vehicle’s battery. This will guard against any unexpected shutdown of the equipment and will ensure that there is always sufficient power to start your vehicle.
•With the engine running the vehicle’s battery has much more capacity available and at a higher voltage. If the Inverter is shut- ting down due to an excessive load with the engine off, keeping the vehicle’s engine running may remedy the problem.
Warning! Do Not Run Your Vehicle’s Engine in a Garage or Other Enclosed Area!
If you are running your vehicle’s engine while stationary to power the portable electronic device you have plugged into your Inverter, or to
Operation of Your Inverter’s Automatic Safety Shutdown Features
Warning! Do not touch the tip of your Inverter’s cigarette plug adapter after use. The plug may be hot and could burn your skin or ignite flammable materials. Allow your Inverter’s cigarette plug adapter to completely cool before storing it in a safe place.
DC Power Source Requirements
Your Inverter must be connected only to vehicles with a DC power source rated at a nominal output voltage of 12 Volts. Your Inverter will not operate from a 6 Volt battery and will be damaged if it is connected to a 24 Volt battery. The power source must provide between
The power supply must also be able to deliver the current necessary to operate the load created by the portable electronic device that you are intending to power. As a rough guideline, divide the power consumption of the device (in Watts) by 12 (the nominal input voltage) to obtain the current (in Amps) the power source must deliver. Example: If a device is rated at 120 Watts; the power source must be able to deliver: (120/12) = 10 Amps. Most vehicular 12 Volt cigarette lighter outlets have fuses that will permit the outlet to draw between 15 and 20 Amps.
AC Power Draw Guidelines
Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in Amps or Watts. Be sure that the continuous power consumption of the device you wish to power is rated at 120 Watts or less. If the power consump- tion of the device is rated in Amps, simply multiply by the AC volts (115) to determine the wattage. For example, a power drill rated at 1 Amp will draw 115 Watts. Do not use your Inverter to operate a device that requires more than 120 Watts of continuous power.
Troubleshooting
“Buzzing” sound in audio
Television
•Position your Inverter as far as possible from the television, the antenna and the antenna cables.
•Adjust the orientation of your Inverter, the antenna cables, and the TV power cord to minimize interference.
•Make sure that the antenna feeding the TV provides an adequate (“snow free”) signal and that high quality, shielded antenna cable is used.
