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).  
 
 
12.2.2.6  Setpoint: BusLNomVph-ph 
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
