Power supply
The bus node has separate operating and load voltage
supplies. The bus node also supplies voltage to equipment
connected via the I-port interface.
Note
•
Use only PELV circuits for the electrical power supply in
accordance with IEC/EN 60204-1
(Protective Extra-Low Voltage, PELV).
•
Observe the general requirements in accordance with
IEC/EN 60204-1 for PELV circuits.
•
Use only voltage sources that guarantee a reliable elec-
tric separation of operating and load voltage in accord-
ance with IEC/EN 60204-1.
•
Always connect both circuits for operating and load
voltage supply.
Through the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is en-
sured in accordance with IEC/EN 60204-1.
Note
Fieldbus participants of different manufacturers have dif-
ferent tolerances regarding the power supply to the bus
(V+, also designated as CAN_V+ or CAN+).
– Tolerance range of the power supply to the bus of the
fieldbus interface CTEUDN: DC 11 … 30 V, reverse polar-
ity protected
Observe this fact when placing the power supply unit and
designing the fieldbus length.
