To maintain the best possible performance and reliability of the drive, inspect the drive annually. Contact ABB
Service at least once in three years for replacement of aging components.

Heatsink

The drive heatsink fins pick up dust from the cooling air. The drive can run into
overtemperature warnings and faults if the heatsink is not clean. When necessary, clean
the heatsink as follows:
WARNING!
Obey the instructions in chapter
instructions can cause physical injury or death, or damage to the equipment.
WARNING!
Use a vacuum cleaner with antistatic hose and nozzle. Using a normal vacuum
cleaner creates static discharges which can damage circuit boards.
1. Stop the drive and disconnect it from the power line. Wait for 5 minutes and then make
sure by measuring that there is no voltage. See section
work (page 13) before you start the work.
2. Remove the cooling fan(s). See section
3. Blow clean, dry and oil free compressed air 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 dust entering adjoining equipment, perform the cleaning in another
room.
4. Reinstall the cooling fan(s).
