E-bus

The E-bus is the data path within a terminal strip. The E-bus is led through from the Bus Coupler through all
the terminals via six contacts on the terminals' side walls.
2.1.4 Power contacts
The operating voltage is passed on to following terminals via three power contacts. Terminal strip can be
split into galvanically isolated groups by means of potential feed terminals as required. The power feed
terminals play no part in the control of the terminals, and can be inserted at any locations within the terminal
strip.
