Distributed I/O Device ET 200M
EWA-4NEB780600602-06
5.1.2 Operating the ET 200M with Process I/O Modules on a
Grounded Supply
This section contains information concerning the overall configuration of an
ET 200M system with a grounded incoming supply (TN-S system). The specific
subjects discussed are:
Circuit-breaking devices, short-circuit and overload protection in accordance
with DIN VDE 0100 and DIN VDE 0113
Load power supplies and load circuits.
Definition: Grounded Supply
In a grounded supply, the neutral conductor of the system is grounded. A simple
ground fault between a live conductor and ground or a grounded section of the
plant causes the protective devices to trip.
Components and Protective Measures
Various different components and protective measures are prescribed when setting
up an entire plant. The types of component and the degree to which the protective
measures are binding depend on the DIN VDE regulation that applies to your plant
setup. The following table refers to Figure 5-1.
