2-2 INSTALLATION
2.3 Site Requirements
The FCC requires telecommunications equipment to withstand electrical surges
which may result from lightning strikes; the TAINET Network Series Modem meet
the requirements set forth by the FCC. The following procedure outlines some
common practices which can minimize the risk of damage to computer equipment
from electrical surges.
1) Make sure the electrical service in your building is properly grounded as described
in article 250 of the National Electrical Code (NEC) handbook.
2) Verify that a good copper wire of the appropriate gauge, as described in Tables
250-94/95 of the NEC Handbook, is permanently connected between the
electrical service panel in the building and a proper grounding device such as:
A ground rod buried outside the building at least 8 feet (2.44 meters) deep in
the earth.
Several ground rods, connected together, buried outside the building at least 8
feet (2.44 meters) deep in the earth.
A wire (see tables 250-94/95 of the NEC handbook for gauge) that surrounds
the outside of the building and is buried at least 2.5 feet (.76 meters) deep in
the earth. Note: The three grounding devices described above should be
firmly placed in the earth. Soil conditions should not be dry where the device
is buried.
A metal water-supply pipe connected to the water main in the street or a
metal cased well. The water pipe used must not have plastic piping between
the ground connection and the water main (or the well). The connection should
be made where the pipe enters the building. The water meter must be shunted
by a copper strap.
3) If you are unsure whether the electrical service in your building is properly
grounded, have it examined by your municipal electrical inspector.
4) Install a surge protector between the modem and AC power outlet. Any
additional computer equipment you have connected to the modem (directly or
through another device), such as a terminal or printer, should also be plugged
into the same surge protector. Make sure that the surge protector is properly rated
for the devices you have connected to it.
5) Call your telephone company and ask them if your telephone line is equipped
with a circuit surge protector.
6) If you are operating the modem in an area where the risk of electrical surges form
lightning is high, disconnect the modem form the telephone line at the modem's
rear panel when it is not in use.
