Outdoor Grounding System
If this product connects to an outdoor antenna or cable system, be sure the antenna or cable system is
grounded (earthed). This provides some protection against voltage surges and built-up static charges.
Article 810 of the National Electric Code (NEC) ANSI/NFPA No. 70-1990, provides the following
information:

Grounding of the mast and supporting structure

Grounding the lead-in wire to an antenna discharge unit

Size of the grounding conductors

Location of the antenna-discharge unit

Connection to grounding electrodes

Requirements for the grounding electrodes (see the following antenna grounding diagram as
recommended by NEC ANSI/NFPA 70)
WARNING: Avoid electric shock and fire hazard! Do not locate an outside antenna
system in the vicinity of overhead power lines or power circuits. Touching power lines
or circuits might be fatal.
Ground the Product
WARNING: Avoid electric shock and fire hazard! If this product connects to coaxial
cable wiring, be sure the cable system is grounded (earthed). Grounding provides
some protection against voltage surges and built-up static charges.
Protect the Product from Lightning
In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.
Verify the Power Source from the On/Off Power Light
When the on/off power light is not illuminated, the apparatus may still be connected to the power
source. The light may go out when the apparatus is turned off, regardless of whether it is still plugged
into an AC power source.
