4.2.10.6 Protective separation via 10BaseFL
There are two ways to achieve protective separation of the operator and engineering
stations and the AC 800F, which will be described below. Note that the power supply
modules SA 801F/SA 811F of the AC 800F are provided with a protective separation.
When establishing one of the separations described below make sure that the AUI or
CAN cable shields are grounded properly.

Fig. 4-27 Protective separation via Ethernet, 1st way
In this case all nodes are linked via a fiber optic cable. This provides for protective
separation of the nodes from each other and makes long distance links possible.
