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 INVT.
 Read and follow the instructions in chapter Safety Precautions. Ignoring the
instructions would cause physical injury or death, or damage to the equipment.
1. Stop the inverter and disconnect it from the AC power source and wait for at least the time designated on
the inverter.
2. Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder slightly upward
from its front edge.
3. Disconnect the fan cable. Remove the installation bracket.
4. Install the bracket to the reversed direction. Pay attention the air direction of the inverter and the fan as the
figure below:
