EUCHNER EKS FSA with Profibus-DP Interface - Manual (Page 12)

Manual EKS Electronic-Key Adapter Profibus-DP
4.2 Technical data, Electronic-Key adapter
Attention!
All the electrical connections must either be isolated from the mains supply by a safety transformer
according to EN IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent
isolation measures.
