If both are NSAU, then break the IEC 61850 connections for ECM on Secondary CRU,
such that protocol Outputs are not driven by Secondary ECM.

If both are NSAU, then the unit which was Standby before the link break, should be
put in STOP mode. This will ensure that protocol Outputs are not driven by two
