Fans; Replacing The Cooling Fan Of The Supply Module (Frame D7T) - ABB ACS880-04 Hardware Manual

Fans

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