92 Maintenance

Heatsink

Check the cleanliness of the cabinet and the surroundings. When necessary, clean
the interior of the cabinet with a soft brush and a vacuum cleaner.
The module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. When necessary,
contact ABB for cleaning of the heatsink.

Fan

The lifespan of the cooling fan depends on the drive usage and ambient
temperature. See the appropriate ACS800 firmware manual for the actual signal
which indicates the running time of the cooling fan. For resetting the running time
signal after a fan replacement, please contact ABB.
Replacement fans are available from ABB. Do not use other than ABB specified spare
parts.
