Referenced Standards

All installation stages should  fully conform to the latest editions of all relevant standards, including the following:
1. ANSI/TIA-568
2. ANSI/TIA-569
3. ANSI/TIA-570
4. ANSI/TIA-606
5. ANSI/TIA-607
6. ANSI/TIA-758
7. ISO/IEC 11801
8. ISO/IEC 14763
9. ISO/IEC 18010
10. CENELEC EN 50173
11. CENELEC EN 50174

Basic installation guidelines

1. Avoid any cable abuse, including kinking, twisting and crushing.
2. Maximum pulling tension of horizontal cable should not exceed 8 Kgf (78N).
3. The cable path should not include more than 3 turns of 90° in each link.
4. The dynamic bend radius should be minimum 8 times the cable OD.
5. The static bend radius should be minimum 4 times the cable OD.
6. Avoid proximity to power cables, transformers, elevator shafts and any other source of EMI.
7. Avoid any proximity to heat sources.
8. The cable must never be exposed to temperatures lower than –20C and higher than +60C.
9. During installation the cable temperature and the room temperature must never be lower than 0C and higher than +40C.
10. Indoor cabling cables and components must never be exposed to sunlight, rain and excessive humidity.
11. Whenever possible, do not bundle the cables – lay them as randomly as possible.
12. Avoid creating neat service loops.
13. Use only soft cable ties loosely tied at uneven intervals.
14. During cable termination remove the absolute minimum length of jacket required the keep the pair twist to the point of connection.
15. Always use proper tools and equipment for installation and testing.

Length limitations

The 3 major LAN cabling standardization groups (namely TIA, ISO/IEC and CENELEC) specify different cabling length limitations.

The following are the compiled HCS length limitations, applicable to all categories and classes, except Category 6A & Class EA cabling:
Note: There shall be no more than 4 connectors in any permanent link or channel.

Cabling Segment	Min. Length m	Max Length m
Permanent Link	15	90
Channel (electrical length)	19	100
Floor distributor to Consolidation point	15	85
Consolidation point to Wall outlet	5	-
Floor distributor to Wall outlet (no CP)	15	90
Work area cord - CP link	2	5
Work area cord - no CP	1	5
Equipment cord - CC link	2	5
Equipment cord - no CC	1	5
Patch cord	2	10
Total cord lengths	-	10

In addition to the basic installation guidelines, the following requirements and limitations shall be utilized when installing Category 6A or Class EA permanent links and channels:

Cabling Segment	Min. Length m	Max Length m
Permanent Link	15	90
Channel (electrical length)	19	100
Floor distributor to Consolidation point	15	85
Consolidation point to Wall outlet	5	-
Floor distributor to Wall outlet (no CP)	15	90
Any modular cord	2	10
Total cord lengths	-	10
