5.10 Potential at control voltage connections
The connections for the control voltage (< 30 V) relate to the common GND potential
(exception: relay contacts are potential-free). There is a potential isolation between the
connections for the control voltage and the PE conductor. It must be ensured that the
maximum external voltage at the connections for the control voltage cannot exceed 30 V
(between the
“
GND
”
and
“
PE
”
conductor terminals). A connection to the PE conductor
potential can be made if required;
fi
t a bridge between the
“
GND
”
terminal and the
“
PE
”
connection (terminal for shield).
