2.1.1 Before Installation

Please read the following notes concerning installation and connecti on before installing the Hybrid IP-PBX
and terminal equipment.
Be sure to comply with all applicable laws, regulations, and guidelines.

Safety Installation Instructions

When installing telephone wiring, basic safety precaution s 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 specific ally 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 Hybrid IP-PBX is designed for wall mounting only, and should be installed in a locat ion 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 the rmal 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 electr ic 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 equipme nt.)
7. Within 1.8 m (6 ft) of radios and televisions. (Both the Hybrid IP-PBX and PTs should be at l east 1.8 m
[6 ft] away from such devices.)
8. Locations where other objects will obstruct the area a round the Hybrid IP-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 Hybrid IP-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 shiel ded 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.
