ventilation technology. The information sheet "Network structure of MODBUS" R-TIL08_01 contains
detailed information about "MODBUS".

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 50V (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).
