ReplacementR
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 17)
before you start the work.
2. Remove the drive module from the cabinet.
3. Remove the module cooling fan(s). See the separate instructions.
