Note: Contact your Yaskawa representative or nearest agent when using the CDBR Braking Unit
(CDBR-†D) with earlier models (CDBR-†, CDBR-†B, or CDBR-†C).
<1> Connect directly to the drive or install a terminal block.
<2> Connect the thermal relay trip contact to disconnect main input power to the drive.
