Interference in data transmission due to unshielded power 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
Additionally required material (not included in the scope of delivery):
☐ One network cable
Cable requirements:
The cable length and quality affect the quality of the signal. Observe the following cable
requirements:
☐ Cable type: 100BaseTx, from Cat5 with shielding S-UTP, F-UTP or higher
☐ Plug type: RJ45 of Cat5, Cat5e, Cat6 or Cat6a. Cat7 plugs cannot be used.
☐ Maximum cable length between two nodes when using patch cables: 50 m
☐ Maximum cable length between two nodes when using installation cables: 100 m
☐ UV-resistant for outdoor use
Procedure:
1. Plug the RJ45 plug of the network cable into the network port X4 or X5 until the RJ45 plug
snaps into place. The assignment of the network cables to the ports is not relevant, as the ports
constitute a switch function.
2. Connect the other end of the network cable to the network.
