phase-phase nominal voltage busLNomVph-ph. The controller will then
recalculate the phase-neutral nominal voltage automatically.
NOTE:
The actual setpoint units and range depend on setting of the Power format in
GenConfig.
NOTE:
If different voltage on BusL and on BusR is required the following procedure
is required:
Both setpoints (BusRNomV and BusLNomV) must be adjusted to the same
values according to the value of actual BusL or BusR nominal voltage. E.g.
BusR nominal is 231 V but BusL nominal is 240 V.
In this case both setpoints need to be adjusted to 231 V and setpoints of
corresponding protections for BusL need to be set assymetrically.
For 240 V on BusL it is typical to open BTB when voltage reaches 254 V or
225 V. Since the setpoint is adjusted to 231 V corresponding protection
setpoints need to be adjusted to BusRight >V = 106% and BusRight <V = 97
% (hence the desired values are reached).

Description
This setpoint is used to adjust the nominal mains voltage (phase to phase).
This setpoint is also recalculated automatically when the phase-neutral
nominal voltage busLNomV is changed.
This setpoint can be used if you know the phase-phase nominal voltage only.
The controller will recalculate the phase-neutral nominal voltage
automatically when this setpoint is changed.
NOTE:
The actual setpoint units and range depend on setting of the Power format in
GenConfig.
NOTE:
If different voltage on BusL and on BusR is required the following procedure
is required:
Both setpoints (BusLNomVph-ph and BusRNomVph-ph) must be adjusted to
the same values according to the value of actual BusL or BusR nominal
voltage. E.g. BusR nominal is 400 V but BusL nominal is 415 V.
In this case both setpoints need to be adjusted to 400 V and setpoints of
corresponding protections for BusL need to be set assymetrically.
For 415 V on BusL it is typical to open BTB when voltage reaches 440 V or
390 V. Since the setpoint is adjusted to 400 V corresponding protection
setpoints need to be adjusted to BusRight >V = 106% and BusRight <V = 97
