Introduction
The ATX power supply is used for supplying the +5V and +12 V for the FirePick Delta electronics. However, the ATX power connector is not very convenient for accessing these voltages. Therefore, a frame was designed which mounts to an ATX power supply that provides a place to mount a break out board that allows easy access to the power lines. By plugging the ATX connector into the back of the break out board, the voltages are now available through simple screw connectors.

Insert the four M3 nuts into the frame nut traps.
-
These nuts will receive the 3X25 mm screws that hold the break out board and cover to the frame.
-
-
-
Peel off the acrylic cover from both sides of the PC02 plate.
-
-
-
Put the M3 screws through the acrylic plate, noting the orientation in the pictures to the left.
-
-
-
Add EPWR02 breakout board as shown. Note orientation.
-
Screw this into the plastic frame housing.
-
-
-
Add rubber feet to the four corners of the power supply as shown.
-
Two on the front orange frame
-
Two on the rear corners of the power supply
-
You may want to rub alcohol onto the area before applying the rubber feet. If there is any grease or dirt, they might not stick for very long.
