Installation
The VPS can be installed on the wall. Please read the following notes concerning
installations and connections before installing the VPS.
Installation Precautions
Avoid installing the VPS in the following places:
(Doing so may result in malfunction, noise or discoloration.)
1
In direct sunlight and hot, cold, or humid places.
(Temperature range : 5 ˚C – 40 ˚C, Relative humidity range : 10 – 70 %)
2
Areas where there are thermal springs, etc. where sulfuric gases may damage the
equipment or contacts.
3
Places in which shocks or vibrations are frequent or strong.
4
Dusty places, or places where water or oil may come into contact with the unit.
5
Near high-frequency generating devices such as sewing machines or electric weld-
ers.
6
On or near computers, telexes, or other office equipment, as well as microwave
ovens or air conditioners.
(It is preferable not to be installed in the same room with the above equipment.)
7
Install at least 1.8 m (6 feet) from televisions.
8
Do not obstruct the area around the PBX and the VPS. (Be especially careful to
allow space for cooling above and at the sides of both systems for maintenance and
inspection.)
Wiring Precautions
Make sure to observe the following instructions when wiring:
1
Do not wire the telephone cable parallel to 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 or the like to protect the wires from
being stepped on. Avoid wiring under carpets.
3
Avoid sharing the same AC power supply for computers, telexes, and other office
equipment. Otherwise, the VPS operation may be interrupted by the induction
noise from such equipment.
