Wiring Precautions
Be sure to follow these instructions when wiring the unit:
a)
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.
b) If cables are run on the floor, use protectors to prevent the wires from being stepped on.
Avoid wiring under carpets.
c)
Avoid using the same power supply outlet for computers, telexes, and other office
equipment. Otherwise, the system operation may be interrupted by the induction noise
from such equipment.
d)
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 Panasonic proprietary telephones (e.g., KX-T7436,
KX-T7235).
e)
The Power Switch of the system must be off during wiring. After all of the wiring is
completed, turn the Power Switch on.
f) Mis-wiring may cause the system to operate improperly. Refer to 5.1.1 Installation and
5.1.2 Connection.
g)
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.
h)
The system is equipped with a 3-wire grounding type plug. This is a safety feature. If
you are unable to insert the plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of the grounding-type plug.
i) Use twisted pair cable for outside line connection.
j)
Outside lines should be installed with lightning protectors. For details, refer to
2.3.9 Installation of Lightning Protectors.
WARNING
Static sensitive devices are used. To
protect printed circuit boards from
