<volt-char>
Concerning voltages, various nominal voltages (<nominal-volt>) can be specified. It is possible to reference to supply connections with the reference mechanism. In the description of the supply connections, any number of voltage ranges with respective operating states can be given to each nominal voltage. Various operating states can be assigned to a voltage range.
