Description This setpoint is used to adjust the nominal bus voltage (phase to neutral). If
you do not know the phase-neutral nominal voltage, you can adjust the
phase-phase nominal voltage BusNomVph-ph. The controller will then
recalculate the phase-neutral nominal voltage automatically.

If different voltage on Mains and on Bus is required the following procedure is
required:
Both setpoints
values according to the value of actual Bus nominal voltage. E.g. Bus
nominal is 231 V but Mains nominal is 240 V.
In this case both setpoints need to be adjusted to 231 V and setpoints of
corresponding protections for Mains need to be set assymetrically.
For 240 V on Mains it is typical to open MCB when voltage reaches 254 V or
225 V. Since the setpoint is adjusted to 231 V corresponding protection
setpoints need to be adjusted to
the desired values are reached).

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.
