Goodrive20-EU series VFD

Fault tracking

104

Fan failure can be predicted by the increasing noise from the fan bearings. If the VFD is

operated in a critical part of a process, fan replacement is recommended once these
symptoms appear. Replacement fans are available from INVT.



Read and follow the instructions in chapter

Safety Precautions

. Ignoring

the instructions would cause physical injury or death, or damage to the

equipment.

Stop the VFD and disconnect it from the AC power source and wait for at least the time
designated on the VFD.

Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder
slightly upward from its front edge.

Disconnect the fan cable. Remove the installation bracket.

Install the bracket to the reversed direction. Pay attention the air direction of the VFD and
the fan as the figure below:
