108 Maintenance

Recommended annual maintenance actions by the user
ABB recommends these annual inspections to ensure the highest reliability and optimum
performance.

Recommended maintenance intervals after start-up
1) If the inverter is continuously used for reactive power compensation during the night, halve the replacement
interval accordingly. If reactive power compensation is used only partially, check the operating hours of fans
in the Inverter control program parameter 01.31 FAN ON-TIME. Reset the counter when the fans are
replaced.
2) Estimated maintenance interval in ideal conditions: ambient temperature between 0…40° C (104 °F), indoor
conditioned (IEC62109), and no cyclic heavy load.
3) If operation temperature is continuously below 40° C (104 °F), replacement after 12 years. If above 40° C,
replacement after 9 years. Contact ABB for replacement.
