Maintenance 153
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.
Maintenance timers and counters
The control programs have maintenance timers or counters that can be configured to
generate a warning when a pre-defined limit is reached. Each timer/counter can be set to
monitor any parameter. This feature is especially useful as a service reminder. For more
information, see the firmware manual of the supply / inverter unit.
