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 132kW and higher VFD models. If
you need to connect an external DC reactor, take off the jumper between P1 and (+).

Before connecting the braking resistor, remove the yellow warning label with PB, (+) and (-) from
the terminal block; otherwise, poor contact may occur.
