Installing Dc Power - Nortel Meridian 1 Manual

Installing DC power

Use this chapter to install safety ground/protective earth and logic return
wiring, configure system monitors, and connect PFTUs for DC-powered
systems using an MFA150 or 600/48 power system.
Note: The procedures in this chapter apply to the global power
distribution unit (PDU). Throughout this document, the global PDU is
referred to as the "NT4N50AA PDU."
To install reserve power equipment (batteries), follow the instructions
provided with the equipment. To comply with safety requirements, consult
the following articles before working with any battery systems:
— Read the "Material Safety Data Sheet" that must be posted to meet
OSHA requirements. This article outlines appropriate reserve battery
handling procedures.
— Refer to National Electric Code 645-10. This article outlines
requirements that call for the installation of AC- and DC-power kill
switches to battery systems in certain environments.
As a safety precaution, all AC service panels should be located in an area that
is easily accessible at all times to allow for emergency shutdown.
Additionally, each circuit breaker within a panel should be clearly marked to
identify the system component or components it services. An optimal
location would be near, or just outside the entry to the room containing the
DC power system for Meridian 1.
See Appendix A: "NT0R72, NT6D82, QBL12, QBL15, QCA13" on
page 383 in this document to perform one of the following tasks:
— connect an NT6D82 Power System
