(3) Connect a 24-VDC power supply to the brake box and controller and supply the power.
Caution:
 Before connecting each cable/connector, confirm that the connector pins are not bent or
broken and the cable is not damaged, and then plug in the connector firmly.
 When connecting the encoder cable, be sure to confirm the orientation of the connector first.
 Use a dedicated 24-VDC power supply for the brake power, because sharing the I/O power or
secondary circuit power may cause noise to enter the I/O signals or otherwise the brake
operation may become unstable.
 The power supply for the brake must have an output voltage of 24 VDC 10% and power
capacity of 20 to 30 W.
