Heatsink
The heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. In a "normal"
environment (not dusty, not clean) the heatsink should be checked annually, in a
dusty environment more often.
Clean the heatsink as follows (when necessary):
1. Remove the cooling fan (see section
2. Blow dry clean compressed air from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust. Note: Prevent dust from entering
adjoining equipment.
3. Replace the cooling fan.
Fan
The life span of the cooling fan of the drive is about 50 000 (R7) and 60 000 (R8)
hours. The actual life span depends on the running time of the fan, ambient
temperature and dust concentration. See the appropriate ACS550 User 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.
