Cooling fans
Power module cooling fans
The lifespan of the cooling fans of the supply and inverter modules is about 50 000
hours. The actual lifespan depends on the running time of the fan, ambient
temperature and dust concentration. Each supply and inverter module has its own
cooling fan. Replacements are available from ABB. Do not use other than ABB
specified spare parts.
The application program keeps track of the running time of the cooling fan of the
inverter
modules. See the
Firmware Manual
delivered with the drive for the actual
signal which indicates the running time.
