Cleaning
Ventilation
Make sure that the inverter's ventilation slots are not blocked. Check that the fan is
functioning correctly.
Cables and screw terminals
Regularly check the cables for damage, and immediately replace any defective parts.
Regularly check that the screw terminals have been correctly tightened. Retighten the
screws if necessary.
Note
The actual maintenance intervals depend on the installation and operating conditions.
Siemens offers its customers support in the form of service contracts.

6.1.2
Replacing fans
The Power Modules have two fans, an external fan and an internal fan. The external one is
in the heat sink, the internal one is in the enclosure of the Power Module.
Service life of the fan
The average service life of the fan is 40,000 hours. In practice, however, the service life may
deviate from this value. Especially a dusty environment can block up the fan.
The fan must be replaced in good time to ensure that the inverter is ready for operation.
