Note:
1. The fuse, DC reactor, brake unit, brake resistor, input reactor, input filter, output reactor and
output filter are optional parts. See Appendix D "Optional peripheral accessories" for details.
2. When connecting the brake resistor, take off the yellow warning sign marked with PB, (+)
and (-) on the terminal block before connecting the brake resistor wire, otherwise, poor
contact may occur.
