is not in use.
The BCU control unit kit contains:
• BCU-02 or BCU-12 control unit
• memory unit with DC/DC converter control program.
You must connect the control unit to each DC/DC converter module with a pair of fiber optic
cables. You can order them from ABB. See section
Fiber optic cables (page 97) .
You can supply 24 V DC for the control unit from the DC/DC converter module. (Alternatively,
you can take the power supply from another suitable power source). You must acquire the
cables separately. Use a suitable standard installation cable. Use appropriate [X53] plug
