Cooling fans
The cooling fan lifespan is about 60 000 operating hours. The actual lifespan
depends on the drive usage and ambient temperature. See the appropriate ACS 800
firmware manual for an actual signal which indicates the hours of usage of the fan.
Fan failure can be predicted by the increasing noise from fan bearings and the
gradual rise in the heatsink temperature in spite of heatsink cleaning. If the drive is
operated in a critical part of a process, fan replacement is recommended once these
symptoms start appearing. Replacement fans are available from ABB. Do not use
other than ABB-specified spare parts.
Fan replacement (R2i, R3i)
To remove the fan, release the retaining clips. Disconnect the cable. Install the fan in
reverse order.

2. Shift the fan mounting plate to the left and pull the fan assembly out.
3. Disconnect the fan power cable.
