Wiring Precautions
Be sure to follow these instructions when wiring the unit.
1.
Do not wire the telephone cable in parallel with an AC power source, computer, telex, etc.
If the cables are run near those wires, shield the cables with metal tubing or use shielded
cables and ground the shields.
2.
If cables are run on the floor, use protectors to prevent the wires from being stepped on.
Avoid wiring under carpets.
3.
Avoid using the same power supply outlet for computers, telexes, and other office
equipment. Otherwise, KX-TD500's system operation may be interrupted by the induction
noise from such equipment.
4.
Please use one-pair telephone wire for extension connection of (telephone) equipment such
as Single Line Telephones, data terminals, answering machines, computers, Voice
Processing Systems, etc., except Proprietary Telephones (KX-T7220, KX-T7230, KX-
T7235, KX-T7250 etc.).
5.
The Power Switch of the system must be off during wiring. After all the wirings are
completed, turn the Power Switch on.
6.
Mis-wiring may cause the system to operate improperly.
7.
If an extension does not operate properly, disconnect the telephone from the extension line
and then connect again, or turn off the Power Switch of the system and then on again.
8.
Use twisted pair cable for CO line connection.
9.
CO lines should be installed with lightning protectors. For details, please refer to Section
"2.11.1 Lightning Protectors."
10.
To assure good quality telephone connection, it is recommended new and modifications to
existing installation of customer premise wiring shall use solid twisted pair copper
conductors with minimum 24 gauge that comply with the electrical specifications for
Category 3 wiring as detailed in ANSI/EIA/TIA-570A Building Wiring Standards.
