Installing network components in cabinets
3.3 Guidelines for setting up networked automation systems in buildings
In the information shown below, it is assumed that all the components within an automation
system and all the plant components controlled by the system (for example machines, robots
etc.) at least meet the requirements of the European standards for electromagnetic
compatibility in an industrial environment. If devices are defective or incorrectly installed,
higher interference voltages must be expected!
The following is assumed:
● The cables for analog signals, data signals and process signals are always shielded.
● The distance from the cables to the chassis surface of the system (cabinet wall, grounded
Note
In general, the greater the distance between cables and the shorter the distances over
which the cables run parallel to each other, the less the danger of interference.
