Remember that the purpose of connecting an auxiliary power supply APS-
24 to the DC bus of a DDS system is to ensure the supply to all the con-
trol circuits of the power supply and of the drive modules connected to the
DC bus in case of a mains power outage in the auxiliary power supply en-
suring a controlled stop of the moving axes instead of braking out of con-
trol by friction.
Bear in mind that although RPS power supplies come with an internal
auxiliary power supply offering 3 outputs with 24 V DC and a total of 8 A,
192 W, this power may not be enough to feed the control circuits of all the
modules connected or other elements (e.g. a fan). That is why it may be
necessary to also install an APS-24 auxiliary power supply to guarantee
all the power needed.
The APS-24 auxiliary power supply offers 3 outputs with 24 V DC and a
total of 10A, 240 W.
For further information about the auxiliary module APS-24, see chapter 4.
AUXILIARY MODULES in this manual.
Connection of the chokes
These chokes called choke RPS are connected in series with each phase
of the three-phase line between the MAINS FILTER  A and the RPS
power supply module. The following table shows the choke associated
with the power supply:
For further detail, see chapter 6. POWER LINE CONNECTION and chapter
8. INSTALLATION in this manual.
WARNING. Never install an APS-24 to the DC bus of a DDS system with
a regenerative power supply RPS if the reference of the APS-24 is PF
23A or older.
F. H2/43
Version label of the APS-24.
Observe the PF reference on the versions label.
Depending on this reference, it will be possible to con-
nect the APS-24 or not to the DC bus of the DDS sys-
tem with RPS regenerative power supplies.
INFORMATION. It will not be necessary to install external protection fus-
es in these power lines of the auxiliary power supply. They are already in-
tegrated in the power supply itself.
i
INFORMATION. RPS regenerative regulated power supplies, unlike XPS,
regenerative power supplies do not have connection terminals called CH1
and CH2 at the bottom of the module for connecting the chokes.

MANDATORY. Chokes are a must to limit the current circulating from the
power bus to mains.
