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 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 the BCU control unit.
If a direct-on-line fan (option +C188) is used, connect the fan supply (400 V AC / 50 Hz /
60 Hz) to the module control connector [X50:1-3].
If an internal heater (option +C183) is used, connect the supply for the heating resistor to
the DC/DC converter module control connector [X50:7-8].
For the connectors, see the hardware description.

BDCL filter module
A direct-on-line fan (option +C188) is used in the BDCL filter module as standard. See

For the filter connectors, see the hardware description. For the details about supply voltage
levels and auxiliary circuit current consumption, see the technical data.

Connection procedure
Note: The instructions below are based on an example cabinet construction. They are not
applicable to all possible solutions but only clarify the principles.
The following procedure instructs how to connect the control cables of a DC/DC converter
unit. In the example, the power cables are routed to the cabinet through the bottom.
WARNING!
Obey the safety instructions given in ACS880 multidrive cabinets and
modules safety instructions (3AUA0000102301 [English]). If you ignore
the safety instructions, injury or death, or damage to the equipment can
occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
1. Open the cubicle door.
2. Remove the shrouds (if any) from the cubicle.
3. Run the cables into the cabinet. If possible, arrange for a 360° grounding of the cable
shield at the cable entry through.
