9.3 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 P07.15.
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. Spare fans are also available.

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