Installation and Operations Manual
NEBS GR-1089-Core Information
This product is suitable for installation in a Common Bonding Network (CBN).
“
WARNING:
The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or
unexposed wiring or cabling only. The intra-building 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 intra-building 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.”
“Intended to be installed in Network Communications Facilities and in locations where the NEC applies.”
This product has a common DC return (DC-C) terminal.
In the DC-C configuration, the ampacity of the conductor connecting the equipment frame to the BR conductor
shall
be equal
to or greater than the ampacity of the associated BR conductor.
