For applying the proper input voltage to unit
Make sure the power supply is completely unplugged and disconnect from any power.
Remove the vented metal cover by removing the screws (on one side) holding the cover in
place. Be careful not to touch any of the electronic components with your hands or fingers.
Look on the PC Board for a wiring harness with three (3) heavy wires attached (usually Red,
Brown and Orange color).
This harness is plugged into a 3-pin socket that configures the power supply for 115VAC.
Carefully unplug the harness and plug it into the 2nd socket, located next to this socket. This
2nd socket is marked 220VAC/240VAC. Your power supply is now designed to work on 220VAC/
240VAC primary power.
If you have a different type of electrical wall outlet, you may need to change the primary
power cable and/or plug. Please observe all local and national electrical codes.
