Note:
 The fuse, braking resistor, input reactor, input filter, output reactor, output filter are optional
parts. Please refer to Appendix C "Optional peripheral accessories" for detailed information.
 Remove the yellow warning labels of PB, (+) and (-) on the terminals before connecting the
braking resistor to ensure proper connection.
