Note:
• The maintenance and component replacement intervals are based on the
assumption that the equipment operates 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. Contact
your local ABB Service representative for additional maintenance
recommendations.
