ReplacementR
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.
