Connecting The Auxiliary Conductor Terminal 3Kc9822-, 3Kc9832- For A Three-Phase 3-Wire Network (3-Pole) - Siemens SENTRON Manual

6.3.5.3 Connecting the auxiliary conductor terminal 3KC9822-, 3KC9832- for a three-phase 3-
wire network (3-pole)
The auxiliary conductor terminal connection kit 3KC9822-, 3KC9832- for three-phase 3-wire
networks without neutral enables voltage measurement and thus automatic transfer of the
transfer switching equipment (ATSE).
Note
The auxiliary conductor terminal connection kit contains only voltage measurement by inputs
103-106 and 203-206. The power supply for the transfer switching equipment must be
implemented using two 3KC9824-1 autotransformers (400 V / 230 V).
After you have mounted the auxiliary conductor terminal connection kit between the
connecting terminals in accordance with the section titled Installing accessories for the
electronic module (Page 89), you can connect the electronic module with the accessories. In
doing so, the inputs for voltage measurement (103-106 and 203-206) are connected.
1. To connect the accessories with the electronic module, proceed as shown in the figure.
