NEBS Required Statements

NS7 CG X2 systems are designed for installation into a Central Office or similar
telecommunications environment.
NS7 CG X2 are suitable for installation as part of a Common Bonding Network (CBN).
To ensure proper electrical contact when grounding a NS7 CG rack:
◦
Use a ground cable of the same or larger size than the largest DC input power
conductors, using a 40º C correction factor.
◦
Use a cable constructed of copper, 75° C minimum rated.
◦
Use only Listed two-hole copper compression-type lugs for the ground connector.
◦
Before making any crimp connections, coat bare wire and base connectors with
antioxidant.
◦
Use star washers between the lug and rack ground rail to ensure proper ground contact
and anti-rotation.
The Battery Return (BR) Input Terminals are considered to be an Isolate DC Return (DC-I).
NS7 CG X2 systems are suitable for connection to intrabuilding or non-exposed wiring or
cabling only. Unshielded, twisted-pair (UTP) cables may be used for NEBS and non-NEBS
installation.
WARNING!
connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of
the equipment or subassembly MUST NOT be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 5) and require
isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
