This eliminates the need for complex and time-consuming single wiring. One way to power several devices is to use the RNF22 power and error message modules, which also offer short-circuit and line break detection. These modules also enable redundant power feed-in where necessary. - Page 26 Appendix: system overview of RN Series RNF22 1.1 1.2 1.1 1.2 1.1 1.2 1.1 1.2 1.1 1.2 1.1 1.2 1.1 1.2 2.1 2.2 2.1 2.2 2.1 2.2 2.1 2.2 2.1 2.2 3.1 3.2 3.1 3.2 3.1 3.2 3.1 3.2 3.1 3.2 3.1 3.2...
