1 Introduction
General This product manual (Select Code 157-005-102) describes the
J85568E-1 Secondary DC Distribution Mini-Bay. This unit is
also known as a Mini-Battery Distribution Fuse Bay
(Mini-BDFB) or Mini-Battery Distribution Circuit Breaker Bay
(Mini-BDCBB). Complementing the 7-foot, 9-foot and
11.5-foot J85568C-1 series of DC Power Distribution Bays, the
Mini-BDFB/BDCBB is a fully assembled rack-mountable unit
that distributes -48 volt dc power in a two-load (A/B)
arrangement.
The Mini-Distribution Bay is a secondary fuse distribution
center for dc power delivered from a central office battery plant
to the using equipment. When floor space is minimized, the
Mini-Bay provides a cost-effective solution for distributing
power without sacrificing reliability or features. It is ideal for a
small central office or customer premise power system
application. It is also well suited for power transition or
modernization projects or for satisfying co-location
requirements for RBOCs to provide dc power access to
Inter-Exchange Carriers (IXCs).

2 Product Description
Overview TheJ85568E-1 Mini-DistributionBay (Power DistributionBay)
distributes -48Vdc power in a two-load arrangement, with a
300-ampere capacity per load. There are four fuse or circuit
breaker panel positions. Load Bus A connects the top two fuse
or circuit breaker panels. Load Bus B connects the bottom two
fuse or circuit breaker panels. All panel positions must be
equipped with either a fuse or circuit breaker panel or a blank
panel. Each fuse panel is equipped with twelve fuse blocks for
0-60A fuses. Each circuit breaker panel has 12 empty positions
for up to 12 circuit breakers.
This Mini-Distribution Bay is designed to mount in a 23-inch
relay rack. See Figure 2-1. It can also be factory installed in an
ED8C800-50
7′framework. See Figure 2-2. If the Mini-Distribution Bay is
installed in a 7′framework that will be located in a 9′or 11′-6″
environment, bay extenders are available. Ordering information
for the extenders is given in Section 3. Note: Do not mount
Mini-Distribution Bay onto bay extenders. Other equipment
can be added to this framework, which saves valuable floor
space.
The Mini-Distribution Bay offers the same fusing and alarm
monitoring features as the J85568C-series distribution bay, but
in a more compact design. It provides another Lucent
Technologies alternative to secondary distribution requirements.
Features The following is a list of features provided with this product:
• Fully assembled unit for simplified installation
• Lexan rear protective cover

3 - 2 Ordering Information Issue 4 January 1999
1. The engineer must furnish all terminal lugs for load and
return leads. Hardware for terminating load leads, load
return leads, input battery and return cabling, and frame
ground is provided with List 2.
2. This Mini-Distribution Bay is configured with two load
buses. Load Bus A connects the top two fuse or circuit
breaker panels. Load Bus B connects the bottom two fuse
or circuit breaker panels. Battery cabling is connected to
each load bus at the top of the unit. A 300A shunt and bus
bar assembly connects battery cabling to each fuse or
circuit breaker panel as required.
3. A digital meter and switch assembly is provided with List
2 in accordance with ED83127-30 Group 14 to monitor the
300A shunts associated with each load.
4. This Mini-Distribution Bay is recommended for top load
feed applications. When bottom load feed is required, the
J85568C-1 bay is recommended because it provides for
cable routing to the floor.
Terminal Lugs Table 3-B lists recommended terminal lugs for different cable
sizes. Hardware for terminating the terminal lugs is provided
with the Mini-Distribution Bay. Recommended torque for these
connections is 260 in. lbs.
Refer to Table 3-C for recommended terminal lugs for the frame
ground connection. Hardware for connecting the frame ground
is furnished with the Mini-Distribution Bay.
Table 3-D provides recommended terminal lugs for terminating
to the fuse block for List C.
Table 3-D provides recommended terminal lugs for terminating
to the circuit breakers for List D.
