WAGO-I/O-SYSTEM 750
750-882 Media Redundancy ETHERNET Controller
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.
