TP-Link tl-sg1048 manual Requirements for Cabling Indoors

Gigabit Unmanaged Switch

■■ Requirements for Cabling Indoors

When cabling indoors, keep a certain distance away from the devices that may cause high-frequency interferences, such as down-conductor cable, powerline, power transformer and electromotor.

■■

■■

The main cable should be paved in the metal raceway of the access shaft. When cabling, keep the loop area formed by the cable itself as small as possible.

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

	Ethernet Cable
Other Pipelines
	Min Parallel Net Length L	Min Parallel-overlapping
	(mm1	Net Height 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
		Length (mm1
	Parallel cabling	130
<2kVA
	One is in the grounded metal raceway or metal pipe	F0
powerline
	The both are in the grounded metal raceway or metal	10
