Replacing the cabinet fan

By default, the cabinets of frame size BC are equipped with mounted cabinet fans.
The service life of the device fans is typically 50000 h. In practice, however, the service life
depends on other variables (e.g., ambient temperature, degree of cabinet protection, etc.)
and, therefore, may deviate from this value.
The fans must be replaced in good time to ensure the availability of the SINAMICS DC
MASTER Cabinet.
Preparatory steps
● Put the cabinet into a safe state
● Allow unimpeded access.
