Interference in data transmission due to unshielded energy cables
If unshielded power cables are used, they generate an electromagnetic field during operation
which may induce interference in network cables during data transmission.
• When laying network cables, observe the following minimum clearances to unshielded
energy cables:
– For installation without separating strip: at least 200 mm
– For installation with aluminum separating strip: at least 100 mm
– For installation with steel separating strip: at least 50 mm
