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.
