Manual
Version 2.0.1
System supply only with appropriate fuse protection!
Without overcurrent protection, the electronics can be damaged.
If you implement the overcurrent protection for the system supply with a fuse, a
fuse, max. 2 A, slow-acting, should be used.
Figure 7: System Voltage for Standard Couplers/Controllers and Extended ECO Couplers
Only reset the system simultaneously for all supply modules!
Reset the system by switching the system supply simultaneously at all supply
modules (fieldbus coupler/controller and potential supply module with bus power
supply) off and on again.

Recommendation
A stable power supply cannot always be assumed. Therefore, you should use
regulated power supplies to ensure the quality of the supply voltage.
The supply capacity of the fieldbus coupler/controller or the internal system
supply module can be taken from the technical data of the components.
