Note:
The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output reactor and
output filter are optional parts. See Appendix D Optional peripheral accessories.
P1 and (+) have been short connected by default for the 380V 132kW and higher VFD models. If
you need to connect to an external DC reactor, remove the jumper between P1 and (+).
Before connecting the braking resistor, remove the yellow warning sign marked with PB, (+) and
(-) on the terminal block before connecting the braking resistor wire; otherwise, poor contact may
occur.
Built-in braking units are optional for the 380V 45kW
–110kW VFD models.
