Danger!
Faulty operation in case of earth faults possible
The correct functioning of the safety function is not ensured if an
earth fault occurs.
Possible consequences:
ƒ A failure of the safety function can lead to death, severe
injuries or damage to material.
Protective measures:
The electrical reference point for the coil of the safety relay K
SR
must be connected to the PE conductor system (EN 60204−1,
paragraph 9.4.3)!
