Installation Practices
To meet the stringent requirements of the performance standards,
installation should be carried out in accordance with the
requirements of BS EN 50174 and BS 6701 and tested in accordance
with BS EN 50346. Bonding and Earthing should be carried out in
accordance with BS EN 50310.
The following guidelines highlight some of the key points to be
followed:
•
•
Cables should not be joined to increase length. If cables are
found to be short they must not be re-routed by a less suitable
path, but must be re-run.
Cables must be secured so as to relieve any mechanical stress
on the terminations.
•
Cable ties must be finger tight only. Over tight ties deform the
geometry of the cable and affect its link performance. They
should not be so tight as to distort the outer sheath of the
cable.
•
Cable bundles should be limited to 50 cables to avoid crushing
the lower cables of the bundle.
•
Care must be taken to avoid kinks in the cable during cable
pulling.
•
Any cabling over suspended ceilings must be laid in standard
cable trays and supported every 1.2 to 1.5 meters to avoid
possible movement.
•
The minimum bend radius during installation should be 12x
cable diameter and 4x cable diameter once installed.
•
Do not use undue strain when cable pulling. (Maximum
25lb/110N)
•
Avoid high temperature environments, power cable, lift shafts,
switch gear and other sources of interferance.
•
All cable runs should be concealed, and Cable Routes e.g minitrunking, should be parallel or perpendicular to walls.
•
When cable routes pass through walls the holes must be
sleeved and the cables exit and enter at 90 to the wall.
•
All cables must be free of tension along the entire route, and
cable supports should be used to distribute any strain.
•
All metallic conduit and trunking must be earth bonded in
accordance with the IET wiring regulations.
•
All cable exits must be bushed or sleeved so as not to cause
damage to the cable’s outer sheath.
•
Space should be left to allow for additional cables to be run
in the existing cable routes. It is recommended that conduit
and trays should not be filled to more than 80% fill capacity
therefore leaving a minimum of 25% spare cable route capacity
available for future system expansion.
