The BCU-02 control unit kit contains:
• BCU-02 control unit
• memory unit with brake control program.
You must connect the control unit to each brake chopper module with a pair of fiber optic
cables. You can order them from ABB.
You can supply 24 V DC for the control unit from the brake 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 plug connector X53 for the
connection to the brake module.
