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)!
