5.15 Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50 V (between “GND” terminals and “PE” protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between “GND” terminal
and the “PE” connection (terminal for screening).
