Fans
The lifespan of the cooling fans of the converter depend on the running time of the fan,
ambient temperature and dust concentration. See the firmware manual for the parameter
or actual value which indicates the running time of the cooling fan of the converter
modules. For resetting the running time after a fan replacement, contact ABB.
Replacement fans are available from ABB. Do not use other than ABB specified spare
parts.
All the fans in the converter are of the same type.
