General Safety Practices
The equipment discussed in this document may require tools designed for the purpose being described.
RLH recommends that service personnel be familiar with the correct handling and use of any installation
equipment used, and follow all safety precautions including the use of protective personal equipment as
required.
Caution - Severe Shock Hazard
• Never install during a lightning storm or where unsafe high voltages are present.
• Active T1 lines carry high DC voltages up to 56V. Use caution when handling T1 wiring.
Warning
The intra-building port(s) of the equipment or subassembly is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intra-building port(s) of the equipment 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 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.
