Requirements For Cabling Indoors - TP-Link TL-SL2218 Installation Manual

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.
Other Pipelines
Down-conductor
PE
Service pipe
Compressed air pipe

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.
