Lucent Technologies J85568E-1 Secondary DC Mini-Distribution Bay

5 - 6  Installation 

 Issue 4 January 1999

Frame Ground

The frame ground connection is located on the top rear crossbar. 
Connection is made using a 1/4-inch double hole terminal lug on 
0.625-inch centers. Refer again to Table 3-C for recommended 
terminal lugs for the frame ground connection. Hardware for 
connecting frame ground is furnished with the Mini-Distribution 
Bay.

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
