4.3.3.1 Structure of a 120 V AC/230 V AC area

A 120 V AC/230 V AC area must have a power terminal at one end and an end terminal at

the other.

I/O terminals for these voltage areas can be used between these terminals. The number

of terminals is limited by the system limits of the bus system and the Inline system (see

Section 15, “Inline: Technical data and ordering data”).

ing of the fuse according to the strength of the cable. The maximum fuse value is 8 A. For

additional restrictions, please refer to the data sheets for the power terminals.
