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 program has maintenance timers and 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.

Stop the drive and do the steps in section Electrical safety precautions (page 36) before
you start the work.
2. Examine the tightness of the cable connections. Use the tightening torques given in the
technical data.
Fans
The lifespan of the cooling fans of the drive depends on the running time, ambient
temperature and dust concentration. See the firmware manual for the actual signal which
indicates the running time of the cooling fan. Reset the running time signal after fan
replacement.
Replacement fans are available from ABB. Do not use other than ABB specified spare parts.
