1. A system comprising:
a feed-in device, and
a plurality of field devices electrically connected to the feed-in device;
wherein the feed-in device is configured to provide an electrical energy for electrical energy supply to the field devices,
wherein the feed-in device comprises a monitoring device which is configured to detect spark generation in the electrical energy supply and, based on this, to switch off the electrical energy supply,
wherein the field devices each comprise a first device section having an input terminal for connecting a supply line, and a second device section,
wherein the electrical energy provided by the feed-in device is supplied to the first device section via the input terminal and transmittable from the first device section to the second device section via an electrical energy supply connection,
wherein the second device section comprises a terminal device having at least one output line terminal for connecting at least one output line to forward the electrical energy transmitted to the second device section, and
wherein the electrical energy supply connection of the first and second device sections comprises a power limiting device configured to cause a limitation of an electrical power transmittable from the first device section to the second device section in the course of the energy transmission.
