Ensuring reliable operation
The manual describes a desired state which, if maintained, ensures the required level of
operational reliability and compliance with EMC limit values.
Should there be any deviation from the requirements in the manual, appropriate actions (e.g.
measurements) must be taken to check/prove that the required level of operational reliability
and compliance with EMC limit values are ensured.
