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