The cable has a foil shield with a bare drain wire. The drain wire
should be connected to the enclosure ground at an I/O chassis
mounting bolt or stud. Connect the drain wire at only one end. The
foil and drain at the other end of the cable, which connects to the
device, should be cut short and taped back to insulate it from any
electrical contact.
