116 Maintenance
• Renewal of the whole drive and all optional functional safety module(s) and components.
• Renewal of the components in the safety function circuit. In practice, this is economical
only with larger drives that have replaceable circuit boards and other components such
as relays.
Note that some of the components may already have been renewed earlier, restarting their
mission time. The remaining mission time of the whole circuit is however determined by its
oldest component.
Contact your local ABB service representative for more information.
