2.3 Site Requirements

The FCC requires telecommunications equipment to withstand electrical surges

which may result from lightning strikes; the Network Series Modem meet

the requirements set forth by the FCC. Make sure the electrical service in your

building is properly grounded as described in article 250 of the National Electrical

Code (NEC) handbook. The following procedure outlines some common practices

which can minimize the risk of damage to computer equipment from electrical surges:

* 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:

1) 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.
