With this arrangement there is no neutral conductor available. For this reason, the following
optional accessories can/must be used for establishing this network:
● 2 x autotransformer 3KC9824-1. For information, see the section titled Installing and
connecting an autotransformer (400 V / 230 V) (Page 79).
● The auxiliary conductor terminal kit is required in the case of the 3-pole variant for
connecting the electronic module, and it must be mounted before connection to the
source. See the section titled Connecting the auxiliary conductor terminal 3KC9822-,
3KC9832- for a three-phase 3-wire network (3-pole) (Page 95).
The dual power supply (DPS) accessory is not required with the 3KC8 transfer switching
equipment since it is supplied with power via two inputs of the electronic module.
