CHAPTER 4 : GENERAL INFORMATION AND FEATURES
CHAPTER 2 :
INSTALLATION
2.1 Description
This chapter provides the information needed to install the DT-128 NTU and to ensure that it
is working properly. You may obtain more information about this subject for the DT-128N
from the User's Manual of the TAINET TRS32 Shelf.
2.2 Unpacking
Save the carton and protective packing material in which your DT-128 NTU was shipped; you
might need them for repackaging if you have to store or ship the NTU in the future. The
following items are shipped with your DT-128 NTU:
•
One DT-128 NTU User's Manual.
•
One 7-feet (2.13m) modular telephone cable for connection to an RJ11 4-pin jack.
•
One 6-pin box for twisted line application.
Rough handling during shipping causes most early NTU failure; after you unpack the NTU,
check carefully for shipping damage. Contact the shipper if you notice any damage.
Direct any additional questions about damaged or missing parts to the nearest sales
representative, or contact:
2.3 Site
Requirements
The FCC requires telecommunications equipment to withstand electrical surges which may
result from lightning strikes; TAINET NTUs 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.
