Fans
The lifespan of the cooling fans of the drive depends on the running time, ambient
temperature and dust concentration. See the firmware manual for the actual signal which
indicates the running time of the cooling fan. Reset the running time signal after fan
replacement.
Replacement fans are available from ABB. Do not use other than ABB specified spare parts.
