Rectifier Nominal 120 Vac / 208 Vac / 240 Vac Input And Ac Input Equipment Grounding Connections - Vertiv NetSure-48 VDC Installation And User Manual

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 the 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 4) 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.
The intra-building port (RJ-45) of the equipment or subassembly must use shielded intra-building cabling/wiring that is
grounded at both ends.
