    AC signals, or floated, galvanically isolated, from the local ground. MicroNet XT Control is designed to have the DC termination of shields to ground at the control and float or AC terminate the shield at the opposite end (the field end). The cabinet installation wiring also requires that the IO signal shielding be either AC or DC terminated at the boundary of the cabinet where cables and wiring transition from outside the cabinet to inside it.
