Introduction
General
This product manual describes the J85568C-1 Battery
Distribution Fuse Bay (BDFB). The J85568C series BDFB is
shown in Figure 1-1. It serves as a secondary fuse distribution
center for dc power delivered from a central office battery plant
to the using equipment. It provides space efficient branch
loading for distri/- 24, 48 or 130 volt dc power or
combinations of these voltages from different battery plants. In
many applications, telecommunication equipment requires
power redundancy from the battery plant. A BDFB provides this
redundancy through the use of multiple load buses. The
J85568C-1 is a cabinetized distribution system that supports
these applications by providing up to six distinct load buses.
Each load bus has a rated current carrying capacity of 600
amperes and may be configured to include one or multiple fuse
panels. Each fuse panel provides 20 mounting positions that may
be equipped with either WP-92461 cartridge fuses that range
from 3 to 70 amperes and/or GMT fuse modules containing three
fuses ranging from 1/2 to 5 amperes. Additional features
include: digital meters; remote monitoring capability for alarms;
multiple cabinet heights, and optional 2-hole ground bus
arrangements mounted either in the cabinet or external to the
cabinet on a cable rack. These options and many more provide
greater flexibility for customers with different distribution
requirements.
The topics covered in this manual include a general product
description, basic features and options, ordering guides, and
engineering and installation information. The main emphasis
will be to familiarize the user with alarm options and cabling
issues such as, connector and hardware types available for input
