OverviewThe J85568E-1 Mini-Distribution Bay (Power Distribution Bay)
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

Cabling from the battery plant is terminated to each load on a
single set of 3/8-inch studs on 1.00-inch centers that are located
on the top right of the unit. If more than one cable is required due
to voltage drop considerations, terminal lugs may be mounted
back-to-back.
(A minimum of two 350 MCM battery input/return cables is
recommended per 300 ampere load.)
The Mini-Distribution Bay is equipped with a distribution return
bus located along the left and bottom sides of the unit. The bus
bar has a 600-ampere current carrying capacity and is equipped
with 1/4-inch studs on 0.625-inch centers for terminating the
(48) distribution return leads. There is also a set of 3/8-inch studs
on 1.00-inch centers located at the top of this bus bar for
terminating load return cabling from the battery plant and the
central office ground connection (if required). If more than two
cables are required, terminal lugs may be mounted back-to-back.
Hardware for connecting the terminal lugs is furnished with the
Mini-Distribution Bay. Refer to Table 3-B for the list of terminal
lug options for load return cabling. Table 3-C lists the terminal
lug options available for the distribution return cabling. If
voltage drop considerations require distribution cable sizes
larger than 2 gauge, the installer must gutter tap down to 2 gauge
before connection in the unit. Recommended torque values for
terminating distribution cabling is 75 inch/lbs.
Note
All bus bars used in this product are copper with a solder plate
finish. Bus bars do not require buffing or the application of
no-ox before connection of terminal lugs or other bus bars.

Fuse or Circuit
Breaker Panel
The List C fuse panel is shown in Figure 5-4A. Each panel is
equipped with twelve fuse blocks for 3-60A fuses and an alarm
circuit module. Fuse sizes and ordering comcodes are listed on a
label on the front of the Mini-Distribution Bay. See Figure 5-5.
Recommended alarm fuses are GMT .18A, comcode
402328926. The fuse block is UL listed and uses the WP-92461
List 100-110 series of fuses. These fuses offer a big advantage
over other fuse types in that they are UL recognized to UL
standard 198L “DC INDUSTRIAL FUSES” with a 170 Vdc,
100,000-ampere interrupt rating. These fuses also have color
bands to indicate the amperage rating of the fuse.
The List D circuit breaker panel is shown in Figure 5-4B. Each
circuit breaker panel has 12 circuit breaker positions and an
alarm circuit module. Circuit breaker sizes and ordering
comcodes are listed on a label on the front of the
Mini-Distribution Bay. See Figure 5-5. The circuit breakers are
sized from 3 to 100 amperes. They are UL listed. The circuit
breakers are rated at 80Vdc with a 10,000A interrupt capacity.
There are labels on the front of the fuse or circuit breaker panel
for stamping the type of equipment being powered and the fuse
or circuit breaker size required. Distribution cabling is
terminated to each fuse block or circuit breaker on a 1/4-inch
stud. Table 3-D lists the recommended terminal lugs for fuse
blocks. Table 3-E lists the recommended terminal lugs for circuit
breakers. Hardware for connecting these lugs is furnished with
the Mini-Distribution Bay. The recommended torque value is 75
inch/lbs.
The alarm circuit module, BEP1, consists of two circuits, one for
monitoring power loss to the fuse or circuit breaker panel and the
other monitoring for fuse or circuit breaker failures. Alarms are
indicated by LEDs on the panel and by Form-C contact closures.
A green LED illuminates to indicate power is present on the
panel. If power is lost, the green LED extinguishes and a set of
Form-C contacts operates. When a fuse or circuit breaker
operates, a red LED illuminates on the panel and three sets of
5 - 6 Installation Issue 6 January 2008
J85568E-1 Secondary DC Mini-Distribution Bay
Form-C contacts operate. These alarm contacts are isolated and
referenced as audible, visual, and remote fuse or circuit breaker
alarms. These arbitrary references are provided as a suggested
standard for connecting alarm monitoring equipment.
The signals from the four sets of Form-C contacts from each
alarm module are connected via ribbon cables to an alarm
termination board located at the top of the Mini-Distribution
Bay. This termination board provides a convenient point for
installation to connect alarm monitoring systems. Each set of
contacts is a Form-C or transfer type, i.e., a combination of
normally open (NO) and normally closed (NC) contacts with
one side of each in common (C). Either a closure on alarm or an
open on alarm might be required for the alarm monitoring
equipment.

Meter and
Alarm
Termination
Panel
The top panel on the Mini-Distribution Bay is a meter and alarm
termination panel. It consists of a digital meter and A/B switch
wired to the current monitoring shunts of each load and an alarm
termination circuit board. The purpose of the alarm termination
board is to provide an easy access point for the installer to
connect alarm monitoring equipment to the Mini-Distribution
Bay. The alarm termination board is shown in Figure 5-6. It
contains four 12-position screw type terminal blocks for
monitoring the four sets of Form-C contacts of each fuse or
circuit breaker panel (three for fuse or circuit breaker failure and
one for power loss). Each fuse or circuit breaker panel may be
monitored individually by connecting alarms to each of the four
terminal blocks. The left terminal block is connected to fuse or
circuit breaker panel #1, the next to fuse or circuit breaker panel
#2, the third to fuse or circuit breaker panel #3, and the right
terminal block to fuse or circuit breaker panel #4. Alarm wiring
is connected to the terminal block by simply stripping the wire,
placing the wire in the terminal, and tightening the screw. The
recommended wire size is 22-26 gauge.
There are twelve DIP switches between each terminal block.
Each DIP switch is associated with a terminal block position and
is factory set to the open position. If a frame alarm is needed,
simply close the DIP switches associated with that alarm. See
Table 5-A. Alarm monitoring equipment requires either a
closure on alarm or an open on alarm. When a frame alarm is
needed as one of the alarms, simply close the DIP switch settings
according to Table 5-A. Alarm wiring is connected at P201
terminal block (C contact) and P204 terminal block (NO or NC
contact). For example, if a frame fuse or circuit breaker alarm
(visual) is required with closure on alarm, close positions 1 and
3 on switches SW2, SW4, and SW6. Then connect a pair of
alarm wires to P201
pin 7 (C) and to P204 pin 9 (NO). It may be desirable to monitor
for power loss to load A or B. Connect alarm wiring to pins 1 and
either 2 or 3 (as required) of terminal block P201 or P202 to
monitor load A. Connect a second pair of wires to either terminal
block P203 or P204 to monitor load B. For a frame power loss
alarm, set DIP switches and connect alarm wires as shown in
Table 5-A.
A label depicting the equipment layout, terminal lug options,
and alarm termination board designations is located on the clear
cover on the back of the unit to assist installation personnel. See
Figure 5-7.
