Maintenance and component replacement intervals are based on the assumption that the
equipment is operated within the specified ratings and ambient conditions. ABB recommends
annual drive inspections to ensure the highest reliability and optimum performance.
Note: Long term operation near the specified maximum ratings or ambient conditions may
require shorter maintenance intervals for certain components. Consult your local ABB Service
representative for additional maintenance recommendations.
Cleaning the heatsink
The drive 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, clean
the heatsink as follows.
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death, or
damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
WARNING!
Use a vacuum cleaner with antistatic hose and nozzle, and wear a grounding
wristband. Using a normal vacuum cleaner creates static discharges which can
damage circuit boards.
1. Stop the drive and do the steps in section Electrical safety precautions (page 14) before
you start the work.
2. Remove the drive module from the cabinet.
3. Remove the module cooling fan(s). See the separate instructions.
4. Blow dry, clean and oil-free compressed air from bottom to top and simultaneously use
a vacuum cleaner at the air outlet to trap the dust. If there is a risk of dust entering
adjoining equipment, do the cleaning in another room.
5. Reinstall the cooling fan.
