R Replacement
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.
