1.10 Maintenance and inspection
DA1 variable
frequency drives
are maintenance-free, provided that the
general rating data, as well as the technical data for the specific models in
use, is observed. Please note, however, that external influences may effect
the operation and lifespan of a DA1 variable frequency drive.
Because of this, we recommend inspecting the devices on a regular basis
and carrying out the following maintenance activities at the specified
intervals.

For sizes FS4 to FS8 a conditional repair is possible by qualified and certified
workshops (
section 1.13, “Service and warranty”).
