2.1 SAFETY PRECAUTIONS
Please read the following precautions before installing the VPS.
2.1.1 Installation
The VPS needs to be installed on the wall. Improper placement of the system may result in
malfunction, noise, or discoloration. Avoid installing the VPS in the following places:
•
in direct sunlight; in hot, cold, or humid places
•
in new areas where there are thermal springs, etc. (where sulfuric gas may damage the
equipment or contacts).
•
where shocks or vibrations are frequent or strong.
•
in dusty places or places where water or oil may come in contact with the unit.
•
near high frequency generating devices such as sewing machines, elevators or electric
welders.
•
on or near computers, telexes, or other office equipment; near microwave ovens or air
conditioners. (Ideally, the VPS should not be in the room with these items and should be
at least
1.8m {6 feet}
away from televisions.)
Do not obstruct the areas around the PBX and the VPS.
Both require space above for cooling
and space on the sides for maintenance and inspection.
2.1.2 Wiring
•
Do not wire the telephone cable parallel to an AC power source, computer, etc. If cables are
run near those wires, shield the cables with metal tubing or use shielded cables and ground
the shields.
•
Use protectors if running cables on the floor. Avoid running wire under carpets.
•
Avoid sharing a 120
V AC
power supply for computers, telexes, and other office equipment
with the VPS. Induction noise from such equipment may interrupt the VPS operation.
When making any connections or removing the cover, be sure the power switch is turned off.
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:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
