1)
No capacitive load must be taken into account when using electromechanical components
(e.g. contactors).
2)
A suitable and effective protective circuit is to be provided for inductive loads.
One recommended measure is the use of free-wheeling diodes.
3)
Specifications are applicable only if the safety function is requested at least once a year.
4)
Since all diagnostics tests are carried out during operation, the service life for the proof test interval
is adopted.
