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.
Cleaning the heatsink
The drive module heatsink fins pick up dust from the cooling air. The drive runs
into overtemperature warnings and faults if the heatsink is not clean. When
necessary, clean the heatsink as follows.
WARNING!
Use the required personal protective equipment. Wear protective gloves and
long sleeves. Some parts have sharp edges.
