Goodrive350-19 Series VFD for Crane
 Follow all the "Warning" instructions during the operation. Otherwise, major physical
injuries or property loss may be caused.
 Only qualified electricians are allowed to perform the wiring. Otherwise, damage to
the VFD or braking components may be caused.
 Read the braking resistor or unit instructions carefully before connecting them to the
VFD.
 Connect braking resistors only to the terminals PB and (+), and braking units only to
the terminals (+) and (-). Do not connect them to other terminals. Otherwise,
damage to the braking circuit and VFD and fire may be caused.
 Connect the braking components to the VFD according to the wiring diagram. If the
wiring is not properly performed, damage to the VFD or other devices may be
caused.
The 380V 110kW and lower VFD models are equipped with built-in braking units, and the 380V
132kW and higher VFD models need to be configured with external braking units. Select braking
resistors according to the specific requirements on site.
