3. Installation of the EX-16 System
3.1 Precautions for Installation
3.1.1 Exchange
Pay particular attention to the following points:
* The layout should allow easy servicing and inspection.
* The exchange is compact and lightweight; however, it is important to
ascertain the strength of the wall on which it will be placed.
* The exchange should be grounded. When it is used in combination with
other systems (for example, with a PA system) the exchange should
be connected to the other components for common grounding.
* Choose a low "source noise" AC power supply for the exchange. Line
noise can affect speech quality.
* Make sure that the AC power circuit provides adequate insulation and
capacity.
This high-performance exchange is compact as well as quiet, and can be
easily installed almost anywhere. Areas described below, however, should
be strictly avoided.
* An area where it will obstruct traffic, for example, in a hallway or near
the entrance or exit of a room.
* An area where it will be exposed to fire, heat or direct sunlight. Suitable
ambient temperature is +32°~104°F (0°~40°C).
* A dusty area where it will be exposed to metal dust or dirt.
* Near a storage place for chemicals, oil, etc.
* An area subject to vibration.
* Near high-voltage equipment.
* In a strong electrical field.
* Near equipment vulnerable to the influence of an electrical field.
