INSTALLING THE INVERTER
Power source requirements
The power source for the inverter must provide between 11 and 15 volts DC and must be able to
supply the necessary current to operate the load. The power source may be a battery or a well
regulated DC power supply. To obtain a rough estimate of the current in Amps the power source
must deliver simply divide the power consumption of the load by 10.
Example: If a load is rated at 700 watts AC, the power source must be able to deliver 700 by
10=70Amps.
CAUTION:
The inverter must be connected to batteries with a nominal output voltage of 12 volts
Connecting to the power source
The inverter is equipped with a cigarette lighter plug and battery clip cables (Inverter of 150 watts
output without battery clip cables) for connection directly to the power source.
Using the fused cigarette lighter plug
The cigarette lighter plug is suitable for operating the inverter at power outputs up to 150 watts.
The tip of the plug is positive and the side contact negative. Connect the inverter to the power
source by firmly inserting the cigarette lighter plug into the cigarette lighter socket.
CAUTION:
Connect directly to battery or power source when operating above 150watts.
NOTE:
Most vehicle cigarette lighter circuits use fuses rated at 15 to 20 amps or greater. To operate at
full output use the battery clip cable.
Connecting to a power source using provided cables
If the inverter is to be used for extended periods at power levels above 150 watts, direct
connection to the power source is required. Use the leads provided to connect directly to the 12-
volt power source using the following guidelines
- Check that the inverter is switched off and no flammable fumes are present
- Connect the black cable to the post marked negative (-) on the back panel of the inverter
Connect the black clip to the negative (-) terminal the battery
- Connect the red cable to the post marked positive (+) on the back panel of the inverter.
Connect the red battery clip to the positive (+) terminal of the battery.
- Check that all the connections between battery clips and terminals are secure
CAUTION:
Loose connections may cause overheated wires and melted insulation. Check to make sure you
have not reversed the polarity.
