• DO NOT operate the inverter if you, the inverter, the device being operated or any other surfaces that may come in contact with any power source are wet. Water and many other liquids can conduct electricity, which may lead to serious injury. • Do not place the inverter on or near heating vents, radiators or other sources of heat. • Do not place the inverter in direct sunlight. The ideal air temperature for operation is between 50° and 80°F. • Do not use near open engine compartment.

Before Using Power Inverter 140 It is important to know the continuous wattage of the device you plan to use with the inverter. The Power Inverter 140 must be used with devices drawing 140 watts or less. If the wattage is not marked on the device, an estimate can be made by multiplying the AC input current (Amps) by the AC voltage (110V). Devices like TVs, fans or electric motors require additional power to start (commonly known as the “starting or peak power”).
OPERATING INSTRUCTIONS 1. Push the Power Inverter 140 firmly into the 12V accessory outlet. The LED indicator light should glow GREEN verifying the inverter is receiving power. (If connecting in a vehicle, remove the cigarette lighter from its outlet.) 2. Make sure that the device to be operated is turned OFF. 3. Plug the device into the Power Inverter 140 AC outlet. 4. Turn the device on.
POWER SOURCE Your average automobile or marine battery at full charge will provide an ample power supply to the inverter for approximately 3 hours when the engine is off. The actual length of time the inverter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the inverter. Turn OFF the device plugged into the inverter before starting the engine.
LED INDICATOR and OVERLOAD PROTECTION The LED glows GREEN automatically when plugged into a 12V DC source and will not glow under the following conditions: 1. When the power input from the vehicle’s battery drops to approximately 10 volts, low battery shutdown occurs and inverter shuts off. 2. When the power input the vehicle’s battery exceeds 15 volts, high voltage overload protections occurs. 3. The continuous load demand from the equipment or device being operated exceeds 140 watts. 4.
TROUBLESHOOTING PROBLEM: Low or No Output Voltage Reason/Solution 1. Poor contact at terminals. Unplug and reinsert Power Inverter 140. 2. Equipment being operated is drawing too much power. Use a higher capacity inverter or do not use the device. 3. Inverter is too hot (thermal shut down). Allow inverter to cool. Check for adequate ventilation. Reduced the load on the inverter to rated continuous power output. 4.
