OUTDOOR ANTENNA GROUNDING
If an outside antenna is connected to your tuner or tuner/pre-
amplifi er, be sure the antenna system is grounded so as to pro-
vide some protection against voltage surges and built-up static
charges. Section 810 of the National Electrical Code, ANSI/NFPA
No. 701984, provides information with respect to proper ground-
ing of the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.
a. Use No.10 AWG (5.3 mm2) copper, No.8 AWG (8.4 mm2) alu-
minum, No.17 AWG (1.0 mm2) copper clad steel or bronze
wire, or larger, as a ground wire.
b. Secure antenna lead-in and ground wires to house with
stand-off insulators spaced from 46 feet (1.221.83 m) apart.
c. Mount antenna discharge unit as close as possible to where
lead-in enters house.
d. Use jumper wire not smaller than No.6 AWG (13.3 mm2) cop-
per, or the equivalent, when a separate antenna grounding
electrode is used. See NEC Section 810-21 (j).

TRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810. RA-
DIO AND TELEVISION EQUIPMENT.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer’s at-
tention to Article 82022 of the National Electrical Code that pro-
vides guidelines for proper grounding and, in particular, specifi es
that the cable ground shall be connected to the grounding system
of the building, as close to the point of cable entry as practical.
NOTE TO AUDIO SYSTEM INSTALLER
WHENEVER CONNECTIONS TO OR FROM THE GFA-555SE ARE BEING
MADE, BE CERTAIN THAT THE AC ON/OFF SWITCH OF THE AMPLI-
FIER IS IN THE OFF POSITION, THE AC CORD OF THE AMPLIFIER IS
DISCONNECTED FROM THE AC WALL OUTLET AND THAT ALL AS-
SOCIATED COMPONENTS ARE OFF. Always make certain that the
amplifi er is disconnected from the AC outlet for at least fi ve min-
utes to ensure its fi lter capacitors are discharged before mak-
ing connections to and from the amplifi er. Failure to heed this
precaution may result in damage to the loudspeaker(s) and/or the
amplifi er which is not covered by the Warranty.
