2.
RPS operating mode. Boost to 625 V DC. The value of the bus voltage
will be 625 V DC approx.
Select this configuration if 420 V AC

V
line

400 V AC .
If the features required by the system are not met, choose another switch
configuration to obtain a higher bus voltage.
3.
RPS operating mode. Boost to 600 V DC. The value of the bus voltage
will be 600 V DC approx.
Select this configuration if V
line

400 V AC .
If the features required by the system are not met, choose another switch
configuration to obtain a higher bus voltage.
4.
RB6 operating mode. Maintain at 1.41xV
line
. The bus voltage value will
be the rectified value of the mains peak voltage.
Select this configuration if V
line

440 V AC . Note, however, that the RB6
operating mode can be configured for any line voltage. If it cannot
satisfactorily meet the features required by the system with this switch
configuration, choose another one.

For configurations 2 and 3 as in figure F. H2/39 :
When the voltage command value of the BUS DC (given by the selected
by switch configuration) and the value of the rectified line voltage
(1.41xVline) are very close to each other, the voltage command of the
bus is adjusted automatically a few volts over the peak voltage of mains
issuing the warning
A706
.
The maximum limit of the voltage command allowed at the DC BUS is
725 V DC, so if the adjustment means exceeding this value , the RPS
power supply issues error
A707
.
Note that lowering the line voltage also lowers the BUS DC voltage. The
minimum value is determined by the selected switch configuration.

For configuration 1 as in figure F. H2/39 :
When the user has changed the value of parameter VP5 (650 V DC by
default), any approach of the line voltage to the voltage command of the
DC BUS issues error
A706
without involving any automatic adjustment.
If its default value has not been changed, it will behave the same way as
the rest of the previous configurations.
