INSTALLATION
Installation Manual 27
2.1.2 Wiring
• 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.
• Do not wire the telephone cable parallel to an AC power source, computer, etc. If cables
are run near those wires, shield them with metal tubing or use shielded cables and ground
the shields.
• Use protectors if running cables on the floor. Avoid running cables 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.
Note
If you live in an area that can have frequent power failures, we strongly recommend that you
purchase a suitable UPS (uninterruptible power supply) for your VPS (and PBX if needed).
The power rating of your VPS may be found in the specifications.
