All the units used within a safety function must be considered when calculating the safety
characteristic data.
The safety-related characteristic data (PFH, PFD) are mean values. They have been calcu-
lated at an average ambient component temperature of 40 °C and apply for the ambient
temperature range stated in the technical details.
