7.2.1
An important feature of Inline is its internal potential routing system. The electric connection
between the individual station devices is created automatically when the station is installed.
When the individual station devices are connected, a power rail is created for the relevant
circuit. Mechanically, this is created by interlocking knife and featherkey contacts from the
adjacent terminals.
This potential routing eliminates the need for additional external potential routing or cross-
wiring.

The 400 V AC mains voltage for power-level terminals is not led via the internal station
potential routing. It is supplied via a power connector and is led between two power-level
terminals via power bridges.
