Communication cables characteristics
Follow the listed guidelines when installing the communications cables:
The cable should not be installed near EMI factors, such as:
•
Motors, generators, alternators, and transformers
•
Air conditioners, elevators
•
Radio/television transmitters, signal generators and internal communication networks
•
Cables: within 30 cm. (1 foot) of power lines of less than 5 KVA.
•
Cables should not be within 60 cm. (2 feet) of power lines in the 5-10 KVA range.
Cables should not be within 1.5 meters (5 feet) of power lines of more than 10 KVA. The cables should not
run parallel to power lines for more than 15 meters (49 feet).
It is best to use a single cable for the communication line. If it is not possible to use a continues cable only
one indoors connection is allowed, constructed in one of these options:
1.
Using two connectors with appropriate shielding and cover.
2.
Using a connection box.
For aerial installation, use N.Y.Y. shielded cables.
