Shielding
The shielding of all shielded cables used in the system should only be connected
at one side to one common earthing point in a building (see Figure 15 below). If a
shielded databus cable is routed via more than one plastic device the shielding
from incoming and outgoing cable must be connected.
In case the IP connection is used, take care that the Ethernet FTP cable remains
within a single building. Do make use of a proper router or switcher to isolate
Ethernet cables between various buildings.
