Bose WRV5 manual Antenna grounding

Important Safety Information

18.Use proper power sources – Plug the product into a proper power source, as described in the operating in- structions or as marked on the product.

19.Avoid power lines – Use extreme care when installing an outside antenna system to keep from touching pow- er lines or circuits, as contact with them may be fatal.

Do not install external antennas near overhead power lines or other electric light or power circuits, nor where an antenna can fall into such circuits or power lines.

20.Ground all outdoor antennas – If an external antenna or cable system is connected to this product, be sure the antenna or cable system is grounded. This will pro- vide some protection against voltage surges and built- up static charges.

Section 810 of the National Electrical Code ANSI/NFPA No. 70 provides information with respect to proper grounding 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 electrodes, and requirements for the ground electrode. Refer to the antenna grounding illustration on this page.

Note to CATV system installer

This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the NEC (of USA) that provides guidelines for proper grounding. In particular, it specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as is practical.
