Grounding requirements
General requirements
The 9927 Distributed Base Station Outdoor Cabinet must be grounded by means of an
integrated (multipoint) grounding system. The equipment is susceptible to lightning
surges because it is associated with towers and antennas. It is therefore imperative that the
cell site be properly grounded and that a low impedance path to earth be provided. The
grounding conductors must be as straight and short as possible. No sharp bends or loops
are permitted for grounding conductors.
NOTICE
Equipment Warranty
The equipment warranty can be voided if the guidelines in the National Electrical Code
(NFPA 70), the Canadian Electrical Code, Part 1 (CSA C22.1), or the local code in effect,
as well as the Standard for Installation of Lighting Protection Systems (NFPA 780, latest
edition), and Grounding and Lightning Protection Guidelines for Alcatel-Lucent Network
Wireless System Cell Sites, 401-200-115
are not followed.
