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, 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 (Frames A and B)
Detach the power cable clamp plate and terminal blocks. Release the retaining clips
(arrowed) carefully using a screwdriver. Pull the fan holder out. Disconnect the fan
cable. Carefully bend the clips on the fan holder to free the fan.
Install new fan in reverse order.
Note
: The airflow direction is bottom-to-top. Install the fan so that the airflow arrow
points up.
