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 7-150
All Sherbourn amplifiers are double boxed to survive the
rigors of long distance shipping and arrive to you undam-
aged. The outer box may show wear and tear, but this is
no cause for alarm. The outer box's purpose is to protect
the inner box. If the inner looks heavily damaged, and you
are concerned about damage to the amplifier, please call
Sherbourn Technical Support at 1-877-366-8324.
Inside the laminated inner box, the amplifier is securely
seated between to two reinforced pieces of high-density
impact foam. At first glance, the cardboard backing on
the foam may give the appearance of a third box, but it is
easily lifted to reveal the amplifier, which is wrapped in
static free plastic. The plastic sheeting is tucked under-
neath the amplifier 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 amplifier, but there is a recessed area on each side, al-
lowing you to get your hands under the amplifier and lift it
out of the box.
Note: These amplifiers are HEAVY! Lift with your legs!
Inventory: Included with your 7-150 Amplifier 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 7-150 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 purpos-
es.
