WARNING
Use voltage supplies acc. to EN 50178/VDE 0160 (PELV).
DANGER
● Due to the maximum current carrying capacity of 8 A, protect the volt‐
age supply U externally with a fuse of 8 A (slow).
I
● Only use PELV power supply units with at least 4 times the nominal cur‐
rent required for triggering, as thus, only triggering times of less than
300 ms can be ensured.

The output voltage for the safe outputs disrupts
during this period, as the outputs are not internally

Loss of the safety functions due to the use of
unsuitable voltage supplies.
The module is provided with a parallel re‐
verse polarity protection. This protection is
only temporally limited. To avoid a module
defect, proceed as follows:
