8.8.2 Cooling fan
The VFD's cooling fan has a minimum life span of 25,000 operating hours. The actual life span
depends on the VFD usage and ambient temperature.
The operating hours can be found through P07.14 (accumulative hours of the VFD).
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.
8.8.2.1 Replacing the cooling fan
 Read and follow the instructions in chapter 1 Safety precautions. Ignoring the
instructions would cause physical injury or death, or damage to the equipment.
