The Bus Interface Unit contains the logic power supply needed to operate the I/O modules
connected to it. It mounts on a separate terminal block, to which it and all bus wiring are attached.
The configuration is stored in non-volatile memory located in the terminal block. Both the power
supply and terminal block are described in this chapter.
The Bus Interface Unit has a replaceable 1A, 5x20mm 250VAC slow-blow fuse on the input power
lines. The fuse can be changed without disturbing the wiring of any other modules (instructions are
in chapter 3).
