Operating the ET 200S on a grounded supply

In this section, you will find information on the overall setup of an ET 200S distributed I/O
system on a grounded supply (TN-S system). The specific subjects discussed are:
● Circuit-breaking devices, short-circuit and overload protection according to DIN VDE 0100
and DIN VDE 0113
● Load power supplies and load circuits
Components and protective measures
Various 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 the configuration illustration below:
