Note:

The fuse, DC reactor, 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. If you need to connect to an external DC
reactor, remove the jumper between P1 and (+).

Before connecting a braking resistor, remove the yellow warning label with (+) and (-) from the
terminal block; otherwise, poor contact may occur.

Note:

The number of VFDs that can be paralleled depends on the actual power. A maximum of six
VFDs can be paralleled together.

Both the input side and output side of the master and slave need to be connected with parallel
connection cables of the same length.
