the mounting hooks to the slots in the exhaust box. The hooks should be pointing

Heatsink

Disconnect power before servicing the drive or internal cabinet components.
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 (frame sizes R7 and R8).

Fans

The lifespan of the cooling fan of the drive module is about 50,000 hours. The actual
lifespan depends on the running time of the fan, ambient temperature and dust
concentration. See the appropriate ACS800 firmware manual for the actual signal
which indicates the running time of the cooling fan.
Replacement fans are available from ABB. Do not use other than ABB-specified
spare parts.
