• 5 •
This converter uses a nonsinusoidal waveform.
Therefore, we do not recommend you use it to power the
following devices:
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformerless battery chargers
Doing so may cause the device to run warmer or overheat.
3. FASTENING THE CONVERTER TO A FLAT SURFACE
For convenience, your converter can be fastened to a flat
surface, horizontally or vertically. The area where the converter
is to be fastened must be dry, well ventilated and away from any
combustible material or fumes.
1. Turn off and disconnect the converter.
2. Place the back of the converter with the mounting bracket
against a secure and flat surface.
3. Attach the converter to the flat surface using corrosion-
resistant screws.
4. CONNECTING CONVERTER CABLES
The converter and power source must be in the OFF mode.
Make sure you connect your converter to a 12V
power supply only.
Converter connection:
1. Locate the positive and negative plastic terminals located on the
back of the converter and remove the terminal caps completely.
2. Install the positive (red) cable ring lug onto the positive (red)
terminal screw. Install the negative (black) cable ring lug onto
the negative (black) terminal screw. Tighten each terminal, so
that the cable cannot come loose.
