I : max. length from processor (or sub-station) to most distant BATIBUS point.
L : max. length of overall BATIBUS network.
(1) : isolation between the conductors and the screen or shielding when present;
otherwise between the conductors and the outside surface of the wire.
5.4.5 Special Wiring Precautions
Whenever possible keep the BATIBUS cable at least 20 cm away from power cables.
