Pulse-shaped interference Test voltage Corresponds to degree
of severity
High-energy single pulse (surge) in accordance with IEC 61000-4-5
As of product version 3 of power supply PS (6ES7138-7EA01-0AA0), the over‐
voltage suppressor for the DC 24V supply at the power supply PS is no longer
mandatory.
Surge arresters are required for all signal modules (for appropriate types, see
Appendix Lightning and overvoltage protection (Page 442))
