If you must insert the DPC into a bag by yourself, first lay the DPC horizontally on a flat,
stable surface, sheet metal side down. Orient the DPC with the faceplate facing you.
Carefully insert the DPC connector edge into the opening of the bag, and pull the bag
toward you to cover the DPC.
Never stack a DPC under or on top of any other component.
