Maintenance intervals
The table below shows the maintenance tasks which can be done by the end user. The
complete maintenance schedule is available on the Internet (

For more information, consult your local ABB Service representative
(

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.
