Maintenance
Contents of this chapter
This chapter contains maintenance instructions of the drive modules.
Maintenance intervals
The tables below show the maintenance tasks which can be done by the end user. The
complete maintenance schedule is available on the Internet
(www.abb.com/drivesservices).For more information, consult your local ABB Service
representative ( www.abb.com/searchchannels).
The 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 environmental
conditions may require shorter maintenance intervals for certain components.
