An E2/000 energy chain is used in a sewage treatment plant near Saale. A motor cable drum previously installed on a sand trap scraper of the sewage treatment plant worked unreliably and therefore had to be replaced by an E2/000 energy chain of the Series 2500. In the process the energy chain is exposed to external influences such as H2S gas and strong winds. In addition it permitted only an installation space of 200 mm. The e-chain® is in continuous operation for 24 hours all 365 days.
chainflex® cables were also used for the secure carrying of data. In the overall energy supply system, two CF control cables and a CFBUS bus cable are used.
