Press the ON/OFF switch to the ON position. The red LED indicator will light momentarily, then 1.
the green LED power indicator will light continuously, indicating that the unit is functioning.
Plug the device into the 120-volt AC receptacle.2.
Switch on the device. If an audible alarm sounds or the red LED fault indicator lights up for a 3.
protracted period of time, then either the power source voltage is too low or the current being
drawn by the device is too great.
Monitor the temperature of the device for the fi rst 10 minutes of operation to
determine its temperature. If the temperature of the device becomes excessively hot, it is an
indication that the device should not be used with this Inverter.
When shutting down, fi rst turn the power of the appliance or device off.4.
Remove the power plug from the Inverter’s 120-volt AC receptacle.5.
Turn the Inverter’s ON/OFF switch to the OFF position. A small “chirp” sound will be heard when 6.
you switch it off.
Disconnect the battery clips or the 12-volt power plug from the battery or power source.7.
When removing the power plug from the 12-volt cigarette lighter/accessory socket,
always grasp and pull from the plug. If grasped from the harness, harness damage may occur.
Disconnect the battery or power plug leads from the screw connectors.8.
Battery Use
It is recommended that, if you are using a vehicle battery, you run the engine for 15 minutes every
hour in order to recharge the battery.
The Power Inverter may be used with the engine on or off. However, it may not operate while the
engine is being started, as battery voltage can drop substantially during starting.
The Inverter draws little current from the battery when it is not supplying power to a load. Typically,
this Power Inverter draws less than 0.9 amps. It is recommended that you disconnect the Inverter
from the battery when not in use.
Protective Features
Low Battery Alarm (Red LED will light) - This state is not harmful to the Inverter, but could damage
the power source. An audible alarm sounds when the input voltage drops to 10.5 volts and the
Inverter shuts off when the input voltage drops to 10.0 volts. When ample power is supplied, the
Inverter may then be turned back on.
Over-Voltage Protection (Red LED will light) - The Inverter will automatically shut down when the
input voltage exceeds 15 volts DC.
Overload Protection (Red LED will light) - The Inverter will automatically shut down if the
continuous draw exceeds its maximum rating.
To reset the Inverter:
Unplug all devices from the Inverter. 1.
Disconnect the Inverter from the power source.2.
Reconnect the Inverter to the power source.3.
Verify the wattage before plugging any device back into the Inverter.4.
Temperature Protection (Red LED will light) - If the temperature of the external heat sink reaches
158˚F (70˚C), the Inverter will shut down automatically. Turn the Inverter off. Let it cool down for
about 15 minutes before restarting.
Common Problems
Power tools will start but will not continue to run - Some induction motors (motors without
brushes) may require 2 to 6 times their wattage rating in order to start up. If the power tool runs only
momentarily when power is applied, try to leave the power to the tool on while quickly and repeatedly
turning the Inverter on and off.
Buzzing in audio systems - Some inexpensive stereo systems will emit a buzzing sound from their
speakers when operating from the Inverter. This is because the power supply in the device does not
adequately fi lter the modifi ed sine wave produced by the Inverter.
Television interference - The Inverter is shielded and fi ltered to minimize interference with TV
signals. In some cases, especially with weak TV signals, some interference may be visible. Try the
following corrective measures:
Position the Inverter as far away as possible from the television, the antenna and the antenna •
cable.
Adjust the orientation of the Inverter, the antenna cable and the TV power cable to minimize •
interference.
Use high-quality, shielded antenna cable.•
