Note
:
The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output reactor and
output filter are optional parts. For details, see "Optional peripheral accessories".
P1 and (+) have been short connected by default for the 380V 132kW and higher VFD models. If
the VFD needs to connect to an external DC reactor, remove the short connector between P1
and (+).
When the braking resistor needs to be connected, remove the yellow warning labels marked with
PB, (+) and (-) from the terminal block before connecting the braking resistor wire. Otherwise,
poor contact may result.
