Note:
• 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.
• 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.
