Note:
1. The fuse, DC reactor, brake unit, brake resistor, input reactor, input filter, output reactor, and output
filter are optional parts. Please refer to Appendix D "Optional peripheral accessories" for detailed
information.
2. A1 and A2 are optional parts.
3. P1 and (+) are short circuited in factory for the VFDs of 380 V (≥37 kW), if need to connect with the
DC rector, please remove the contact tag between P1 and (+).
4. Before connecting the brake resistor cable, remove the yellow labels of PB, (+), and (-) from the
terminal blocks. Otherwise, poor connection may occur.
