The Revolution and RXL have a non-detachable power cord. This part provides a place to mount a standard grounded receptacle in the chassis - so that you can use the exact same type of power cord you are probably using to power your PC right now. Designed to be printed without supports.The receptacle should fit very snugly. This bracket is designed specifically to fit the Model 701W-15/26 from Qualtek (http://www.digikey.com/product-search/en?mpart=701W-15%2F26&vendor=189). These are very inexpensive - less than a dollar. The part should fit nice and snugly into any bottom corner of the printer. You will need to alter the wiring under the printer to connect the ground, line, and neutral wires correctly to the receptacle. If you are not comfortable working on high-voltage electrical wiring, then please find a qualified electrician to help you. High voltage can be deadly!!
