Cooling Fans; Supply, Inverter And Brake Module Cooling Fans; Replacing The Fan Of The Supply Module - ABB ACS800 Hardware Manual

Cooling fans

Supply, inverter and brake module cooling fans

The actual lifespan of the fan 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 of the drive application program for the
actual signal which indicates the running time.
