6.1.1 Cooling fan
The inverter’s cooling fan has a minimum life span of 25,000 operating hours. The actual life span depends
on the inverter usage and ambient temperature.
The operating hours can be found through P07.14 (accumulative hours of the inverter).
Fan failure can be predicted by the increasing noise from the fan bearings. If the inverter is operated in a
critical part of a process, fan replacement is recommended once these symptoms appear. Replacement fans
are available from Universal Motors.
Read and follow the instructions in chapter
