Use the suitable terminals, depending on the type of installation - cabinet flush mounting or cabinet surface
mounting. Compared to cabinet surface mounting, the terminal can be mounted rotated by 180° giving easier
access to the terminal screws. The ordering data is specified in Appendix A1.
Solid conductors as well as stranded conductors with or without conductor sleeves can be used as single
cables. Siemens recommends using twin cable end sleeves when connecting two single cables.
