R Replacement
Maintenance and component replacement intervals are based on the assumption that the

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.
