If different voltage on Mains and on Bus is required the following procedure is
required:
Both setpoints (
) must be adjusted to the same
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).

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
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.

The actual setpoint units and range depend on setting of the Power format in

If different voltage on Mains and on Bus is required the following procedure is
required:
Both setpoints (
) must be adjusted to
the same values according to the value of actual Bus nominal voltage. E.g.
Bus nominal is 400 V but Mains nominal is 415 V.
In this case both setpoints need to be adjusted to 400 V and setpoints of
corresponding protections for Mains need to be set assymetrically.
For 415 V on Mains it is typical to open MCB when voltage reaches 440 V or
390 V. Since the setpoint is adjusted to 400 V corresponding protection
setpoints need to be adjusted to
the desired values are reached).
