Power source warning
A label on this product indicates the correct power source for this product.
Operate this product only from an electrical outlet with the voltage and
frequency indicated on the product label. If you are uncertain of the type of
power supply to your home or business, consult your service provider or your
local power company.
The AC inlet on the unit must remain accessible and operable at all times.
Ground the product
WARNING
Avoid electric shock and fire hazard! If this product connects to
coaxial cable wiring, make sure the cable system is grounded
(earthed). Grounding provides some protection against voltage
surges and built-up static charges.
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)
