3.2.2 System Supply

The system is supplied through the fieldbus coupler/controller and, where needed,
through additional supply modules with bus power supplies. The system-side component
electronics are protected against reverse polarity.
Observe the following requirements for system power supply:
• SELV/PELV power supplies shall be used.
• Power must be supplied simultaneously to all system power supply units.
WAGO recommends using the same voltage source to realize the power supply.
• Use a suitable overcurrent protection for each infeed. Product-specific information is
