Installing the charging circuit
The cabinet builder must install and connect the charging circuit. For connections, see the
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 option
+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.
￭ BDCL filter module
For the filter connectors, see the hardware description. For the details about supply voltage
levels and auxiliary circuit current consumption, see the technical data.
