Maintenance 105
Cooling fan
The actual lifespan of the cooling fan depends on the drive usage and ambient
temperature. 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, it is recommended to replace the
immediately after these symptoms start appearing.
Note
: Replacement fans are available from ABB. Do not use spare parts other than
ABB-specified spare parts.
Replacing fan (Frames R1 and R2)
To replace the fan in frames R1 and R2, follow these steps:
1. Detach the power cable clamp plate and terminal blocks.
2. Release the retaining clips (arrowed) carefully using a screwdriver.
3. Pull the fan holder out.
4. Disconnect the fan cable.
5. Carefully bend the clips on the fan holder to free the fan.
6. Install the new fan in the reverse order.
Note
: The airflow direction is bottom-to-top. Install the fan so that the airflow arrow
points up.
