							2.1 Before Installation
28 Installation Manual
2.1 Before Installation
2.1.1 Before Installation
Please read the following notes concerning installation and connection before installing the PBX and 
terminal equipment.
Be sure to comply with all applicable laws, regulations, and guidelines.
Safety Installation Instructions
When installing telephone wiring, basic safety precautions should always be followed to reduce the risk of 
fire, electric shock and injury to persons, including the following:
1.Never install telephone wiring during a lightning storm.
2.Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
3.Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected 
at the network interface.
4.Use caution when installing or modifying telephone lines.
Installation Precautions
This PBX is designed for wall mounting only, and should be installed in a location where it is accessible for 
inspections and maintenance.
To prevent malfunction, noise, or discoloration, avoid installing the system in the following locations:
1.In direct sunlight and hot, cold, or humid places. (Temperature range: 0 °C to 40 °C [32 °F to 104 °F])
2.Areas where sulfuric gases may be present, such as near thermal springs.
3.Areas where shocks or vibrations are frequent or strong.
4.High-dust areas, or places the system may come into contact with water or oil.
5.Near devices that generate high frequencies, such as sewing machines or electric welders.
6.On or near computers, telexes, or other office equipment, as well as microwave ovens or air 
conditioners. (It is preferable not to install the system in the same room as the above equipment.)
7.Within 1.8 m (6 ft) of radios and televisions. (Both the PBX and PTs should be at least 1.8 m [6ft] away 
from such devices.)
8.Locations where other objects will obstruct the area around the PBX. Be especially careful to leave at 
least 20 cm (8 in) of space above and 10 cm (4 in) to the sides of the PBX for ventilation.
9.Do not stack up the optional service cards. To avoid damage to the optional service cards, always use 
the extension bolts.
Wiring Precautions
Be sure to follow these instructions when wiring the unit:
1.Do not run unshielded telephone cables near AC power cables, computer cables, AC power sources, 
etc. When running cables near other noise-generating devices or cables, use shielded telephone 
cables or shield the telephone cables with metal tubing.
2.If cables are run on the floor, use protectors to prevent the cables from being stepped on. Avoid running 
cables under carpets.
3.Avoid using the same AC outlet for computers, telexes, and other office equipment, as noise generated 
by such equipment may hamper system performance or interrupt the system. 
						

							2.1 Before Installation
Installation Manual 29
4.Use 2-pair telephone cables when connecting PTs.
Use 1-pair telephone cables when connecting SLTs, data terminals, answering machines, computers, 
Voice Processing Systems, etc.
5.Unplug the system from its power source when wiring, and plug the system back in only after all wiring 
is completed.
6.Mis-wiring may cause the PBX to operate improperly. Refer to Section 2 Installation when wiring the 
system.
7.If an extension does not operate properly, disconnect the telephone from the extension line and connect 
it again, or turn off the PBX using the power switch, then turn it on again.
8.For safety purposes this unit is equipped with a grounded plug. If you do not have a grounded outlet, 
please have one installed. Do not bypass this safety feature by tampering with the plug.
9.Use twisted pair cable for CO line connection.
10.CO lines should be installed with surge protectors. For details, refer to 2.2.10 Surge Protector 
Installation.
11.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.
