Use shielded twisted-pair cable with a twisted pair for data and a wire or another pair for
signal ground (nominal impedance 100 to 165 ohm, for example Belden 9842) for the wiring.
For best immunity, ABB recommends high quality cable. Keep the cable as short as possible.
Avoid unnecessary loops and parallel runs near power cables such as motor cables.
The following diagram shows the wiring between control units.

Safe torque off (XSTO, XSTO OUT)
See chapter
The Safe torque off function (page 183)
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 (or 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.
