General
The BCU control unit consists of a BCON control board (and a BIOC I/O and power supply
board) built in a metal housing. The BCU is mounted separately from the converter
module(s), and connected to the module(s) by fiber optic cables.
In this manual, the name "BCU" represents the control unit types BCU-02, BCU-12 and
BCU-22. These have a different number of converter module connections (2, 7 and 12
respectively) but are otherwise identical.
