Installing DC power
Candeo DC power systems
NN43021-310
Standard 06.01
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 NT4N49AA PDU.
To install reserve power equipment (batteries), follow the instructions
provided with the equipment. To comply with safety requirements, consult
the following before working with any battery systems.
•
Read the "Material Safety Data Sheet" that must be posted to meet
Occupational Safety and Health Administration (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 DC service panels should be located in an area that
is easily accessible at all times to allow for emergency shutdown. An optimal
location would be near, or just outside, the entry to the room containing the
DC power system for the Large System. Each circuit breaker within a panel
should be clearly marked to identify the system component or components it
services.
The Candeo platform provides a simple, quick to deploy, and easy to operate
power solution. Based upon modular building blocks (rectifiers, System
Manager, DC distribution, and battery connection modules), the system is
designed to power –48 V DC applications. The Candeo platform can be
expanded by adding rectifiers, battery connection modules, frames, and
distribution modules.
There are two types of Candeo systems:
•
Large Candeo (MP481200), which uses 50 A rectifiers and has a
capacity of 1000 A.
•
Small Candeo (SP48300), which uses 30 A rectifiers and has a capacity
of 300 A.
