TP-Link TL-SG3424 manual Ethernet Cable

L2 Managed Switch

■■ Requirements for the distance between Ethernet cable and other pipelines are shown in the table.

		Ethernet Cable
Other Pipelines
	Min Parallel Net Length		Min Parallel-overlapping Net Height
	L (mm1		H (mm1
Down-conductor	1000		300
PE	50		20
Service pipe	150		20
Compressed air pipe	150		20
Thermal pipe (not wrapped1	500		500
Thermal pipe (wrapped1	300		300
Gas pipe	300		20

The two diagrams below demonstrate parallel net length and parallel-overlapping net height.

Note: The above minimum net length/height is required when metal raceway is not used. If any requirements cannot be met, you can add a steel tube or metal raceway for shielding.

■■ Requirements for the distance between Ethernet cable and high-power electric devices are in following tables.

Cable	Pave Way		Min Parallel

<2kVA	Parallel cabling		130
	One is in the grounded metal raceway or metal pipe		70
powerline
	The both are in the grounded metal raceway or metal pipe		10
2~5kVA	Parallel cabling		300
	One is in the grounded metal raceway or metal pipe		150
