Note:
 The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output reactor,
output filter are optional parts. Please refer to Peripheral options and parts for detailed
information.
 P1 and (+) are short circuited in factory for the VFDs of 220V (
≥18.5kW), 460V (G-type≥37kW,
P-type
≥45kW), if need to connect with the DC rector, please remove the jumper between
P1 and
(+) .
 Remove the yellow warning labels of PB , (+) and (-) on the terminals before connecting the
braking resistor; otherwise, poor connection may occur.
