1. For the releases prior to the Release 2.5, the current range is 0...6000 A.
2. For the Release 1.0, the voltage range is 0...150 kV. For the Release 1.5 and Release
2.0, the range is 0...300 kV.
3. For the releases prior to the Release 2.5, the voltage range is 0...300 mV.
4. Only included in the feeder terminal revisions of the Release 2.0 or later, refer to
section "Revision identification" on page 90. Note that this parameter can only be
set via the HMI or the Relay Setting Tool.
5. For the releases prior to the Release 2.5, the division ratio is 0...20000.
