4.6.3 Connect AISG Cables
4.6.4 Connect RF Cables
4.6.5 Connect DC –48 V Power Cable
e following sections describe how to connect all necessary cables to the RU.
Important: Do not use a cable that contains red phosphorus as a ame retardant. is may cause
problems, for example, heat generation and emiing smoke.
Important: Ensure the cable connector gland or clamp is the correct size for the selected cable
diameter to prevent water ingress.
4.6.1
Connect Frame Ground Cable
is procedure describes how to connect a Frame Ground (FG) cable to the RU.
Prerequisites:
■RU mounted and not powered up
■Available AWG ground cable with two hole lug (green or green with yellow stripe, 0.625 mm hole spacing)
■Weatherproong method to prevent moisture intrusion
■13 mm socket
■Philips screwdriver
Danger: Use properly insulated tools and perform all safety
precautions in accordance with local safety practices when working
on or around power terminals, power cables, and power connectors.
Contacting power terminals, uninsulated conductors, cable wiring,
or any connector that could be part of a live electrical circuit can
result in death or serious personal injury.
Danger: Utilisez des outils correctement isolés et appliquez toutes
les précautions de sécurité conformément à la sécurité locale
pratiques lorsque vous travaillez sur ou autour des bornes
d'alimentation, des câbles d'alimentation et des connecteurs
d'alimentation. Contacter bornes d'alimentation, conducteurs non
isolés, câblage de câbles ou tout connecteur pouvant faire partie
d'un un circuit électrique peut entraîner la mort ou des blessures
graves.

Caution: e outdoor equipment must be properly grounded to
provide protection against lightning strikes, voltage surges and built-
up static charges. In the event of a short circuit, grounding reduces
the risk of electrical shock. For installation in the USA refer to
Articles 810-840 of the National Electrical Code, ANSI/NFPA No. 70,
for information with respect to proper grounding and applicable
lightning protection for telecom equipment and cabling. e
installer must also follow any additional local building and electrical
code regulations.
Aention: L'équipement extérieur doit être correctement mis à la
terre pour assurer une protection contre la foudre, les surtensions et
les charges statiques accumulées. En cas de court-circuit, la mise à
la terre réduit le risque de choc électrique. Pour une installation aux
États-Unis, reportez-vous aux articles 810-840 du National Electrical
Code, ANSI / NFPA No. 70, pour obtenir des informations sur la mise
à la terre appropriée et la protection contre la foudre applicable
pour les équipements de télécommunications et le câblage.
L'installateur doit également suivre toute réglementation locale
supplémentaire du code du bâtiment et de l'électricité.
