NEC (National Electrical

Code) Standards

A Note for the Cable Television (CATV) Installer

This reminder is to call the CATV system installer’s atten-

tion to Article 820-40 of the NEC that provides guidelines

for proper grounding and in particular, specifies that the

cable ground shall be connected to the grounding system

of the building as close to the point of cable entry as prac-

tical.

Antenna Grounding Outside the House

If an outside antenna is connected to the receiver, be sure

the antenna system is grounded so as to provide some pro-

tection against voltage surges and built-up static charges.

Article 810 of the National Electrical Code, ANSI/NFPA

70, provides information with regard to proper grounding

of the lead-in wire to an antenna-discharge unit, connec-

tion to grounding electrodes, and requirements for the

grounding electrode. See diagram below.

Cable TV Coaxial Cable, Satellite Dish Cables and Tele-

vision Antennas should be grounded BEFORE the point of

entry into the house.

Always observe proper antenna or satellite dish ground-

ing techniques. When lightning strikes, there is always the

possibility that your antenna or dish (mounted high on the

roof) can become a conduit for lightning and electrically

damage any equipment to which it’s connected. Addition-

ally, proper grounding offers safety to the people using the

audio/video system in the event of an electrical problem.

Unpacking the PRE-1

All Sherbourn preamplifiers are double boxed to survive

the rigors of long distance shipping and arrive to you un-

damaged. The outer box may show wear and tear, but this

is no cause for alarm. The outer box’s purpose is to pro-

tect the inner box. If the inner looks heavily damaged,

and you are concerned about damage to the preamplifier,

please call Sherbourn Technical Support at 978-663-7385.

Inside the laminated inner box, the preamplifier is se-

curely seated between to two reinforced pieces of high-

density impact foam. At first glance, the cardboard back-

ing on the foam may give the appearance of a third box,

but it is easily lifted to reveal the preamplifier, which is

wrapped in static free plastic. The plastic sheeting is

tucked underneath the preamplifier and securely taped. It

is recommended that the plastic sheeting be removed after

the amp is lifted out from the box.

The bottom piece of foam is molded to fit tightly against

the preamplifier, but there is a recessed area on each side,

allowing you to get your hands under the preamplifier and

lift it out of the box.

Inventory: Included with your PRE-1 preamplifier should

be an IEC Class 1 two prong power cord and this manual.

It is important to save all the packing materials and the

boxes in case your PRE-1 ever needs to be moved or

shipped back to the factory for service.

Make sure you keep your sales receipt. It is the only way

for Sherbourn to establish the duration of your Limited

Warranty and it may come in useful for insurance pur-

poses.
