Heatsink

The heatsink fins accumulate dust from the cooling air. Since a dusty heatsink is less
efficient at cooling the drive, overtemperature faults become more likely. In a
"normal" environment (not dusty, not clean) check the heatsink annually, in a dusty
environment check more often.
Clean the heatsink as follows (when necessary):
1. Remove power from drive.
2. Remove the cooling fan (see section
3. Blow clean compressed air (not humid) from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust.
Note: If there is a risk of the dust entering adjoining equipment, perform the cleaning
in another room.
4. Reinstall the cooling fan.
5. Restore power.
