2) This input only acts as a true Safe torque off input in inverter control units. In other applications (such as a supply or brake
unit), de-energizing the IN1 and/or IN2 terminal will stop the unit but not constitute a true safety function.
3) Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and DIO2.
4) Determines whether DICOM is separated from DIOGND (ie, common reference for digital inputs floats). ON: DICOM
connected to DIOGND. OFF: DICOM and DIOGND separate.

External power supply for the control unit (XPOW)
The control unit is powered from a 24 V DC, 2 A supply through terminal block XPOW. With
a type BCU control unit, a second supply can be connected to the same terminal block for
redundancy.
Using an external supply is recommended if
• the control unit needs to be kept operational during input power breaks, for example,
because of continuous fieldbus communication
• immediate restart is needed after a power break (that is, no control unit power-up delay
is allowed).
The X485 connector
The X485 provides a connection for optional CIO-01 I/O module. The following diagram

Safe torque off (XSTO, XSTO OUT)
Note:
The XSTO input only acts as a true Safe torque off input on the inverter control unit.
De-energizing the IN1 and/or IN2 terminals of other units (supply, DC/DC converter, or brake
unit) will stop the unit but not constitute a true safety function.
FSO-xx safety functions module connection (X12)
See the user manual of the FSO-xx module. Note that the FSO-xx safety functions module
is not in use in supply, DC/DC converter or brake units.
SDHC memory card slot
The BCU-x2 has an on-board data logger that collects real-time data from the power modules
to help fault tracing and analysis. The data is stored onto the SDHC memory card inserted
into the SD CARD slot and can be analyzed by ABB service personnel.
