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.
