Installing the charging circuit
The cabinet builder must install and connect the charging circuit. For connections, see
chapter
Example circuit diagrams . Consult ABB for more information on the components
and wirings needed.
Activate and tune the charging function in the control program. For information on tuning
the parameters, see
ACS880 DC/DC converter control program firmware manual
(3AXD50000024671 [English]).
Connecting the external power supply cable for the
auxiliary circuit

R8i DC/DC converter module
The cabinet builder must arrange an auxiliary voltage of 230 V AC (or 115 V AC with
G304) to connector X50 to power the electronics of the DC/DC converter module.
R8i modules contain a power supply (BDPS) that produces 24 V DC from the auxiliary
voltage for the internal circuit boards. The 24 V DC voltage provided by the BDPS is
available on X53, and can used to power up one BCU control unit. It is not allowed to use
the 24 V DC output on terminal X53 for any other purpose than for powering up the BCU
control unit.
If a direct-on-line fan (C188) is used, connect the fan supply (400 V AC / 50 Hz /
60 Hz) to the module control connector [X50.1].
If an internal heater (C183) is used, connect the supply for the heating resistor to
the DC/DC converter module control connector [X50.7].
For the connectors, see Converter module connectors X50…X53 on page 26 .

BDCL filter module
A direct-on-line fan (C188) is used in the BDCL filter module as standard. See
Connecting the BDCL filter on page 73 .
For the filter connectors, see Filter module connectors X30 and X55 on page 28 . See page
159 for the details about supply voltage levels and auxiliary circuit current consumption.
