Note:
 The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output reactor and
output filter are optional parts. For details, see “Appendix D Optional peripheral accessories".

P1 and (+) have been short connected by default for the 380V 0132 and higher VFD models. If
you need to connect to an external DC reactor, take off the short-contact tag of P1 and (+).
 Before connecting the braking resistor, remove the yellow warning label with PB, (+) and (-) from
the terminal block; otherwise, poor contact may occur.
 Built-in braking unit is optional for the 380V 0045 -0110 VFD models.
