CAUTION
Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
Keep circuit boards in their antistatic bags when they are not in use.
Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference #TR-NWT-000870.

B11-48001-01 Fuse Module
GENERAL DESCRIPTION
The B11-48001-01 Fuse Module provides 13 GMT indicating- type fuse circuits and a failure alarm circuit for fusing 400-
type modules in an equipment shelf. The module fits into any
400-type or similar equipment housing and operates on -21 to
-56 VDC input power. The front panel includes 13 indicating-
type GMT fuses and an alarm LED.
CIRCUIT DESCRIPTION
The front panel includes 13 GMT-type fuses and an alarm LED. Fig. 1 shows an illustration of the functional sche-
matic.
FUSES
There are two groups of fuses:
♦F1 through F6
♦F7 through F13
They can be fed independently or using the same battery input.
JP1 AND -BATTERY INPUTS
The module is equipped with a jumper (JP1). This jumper
selects one of the following modes of operation:
♦Single input.
♦Redundant inputs.
♦Two independent inputs.
Refer to Table A.

TABLE A - JP1 STRAP OPTIONS
JP1 strapped 1 & 2
♦Single Input
Connecting one power supply to pins 35 and/or 36 or 31
and/or 32 supplies power to both fuse groups.
♦Redundant Inputs
Connecting one power supply to pins 35 and/or 36 and a sec-
ond power supply to pins 31 and/or 32 parallels both supplies
to provide power to both fuse groups.
JP1 strapped 2 & 3
♦2 independent supplies
Connecting one power supply to pins 35 and/or 36 provides
power to fuse group 1 (fuses 1 through 6). Connecting a sec-
ond power supply to pins 31 and/or 32 provides power to fuse
group 2 (fuses 7 through 13).
CURRENT RATING
Each edge connector pin (35, 36, 31, and 32) is rated at 5 amps,
maximum. If the equipment powered by each fuse group draws
less than 5 amps, only one pin of each group is needed. Refer to
Fig. 1. Use both inputs to each group if:
♦The current draw for each group exceeds 5 amps.
♦A single input is used to provide power to both fuse groups.
FAILURE ALARM CIRCUIT
The failure alarm circuit consists of a regulator transistor, relay
K1, and an LED. The regulator transistor compensates for the
battery voltage and prevents exceeding the voltage rating of the
relay coil. The relay is normally activated. It is non-active only
when the supply battery is lost or one of the fuses fails. When a
fuse fails, negative battery is placed on both sides of the relay
coil, no current flows through the coil, and the relay contacts
return to normal. At the same time, current is provided to the
front panel LED, lighting it.

CIRCUIT DESCRIPTION
Two sets of Form-C contacts activate external alarm circuits
when the relay is not active. Two external alarm inputs at pins
52 & 56 allow the alarm circuit to be operated by an external
contact to negative battery.
EXTERNAL FUSE FEED
Edge connector pin 28 is available for providing power to exter-
nal equipment. -Battery supplied to pin 31, 32, 35, or 36 is
routed directly to pin 28, bypassing any fuses.
INSTALLATION
The actual installation of this module is simple. To install the B11-48001-01 Fuse Module, place it in the proper slot in the
equipment shelf. However, several factors deserve attention
before installation:
JP1 AND -BATTERY INPUTS
Refer to Fig. 2. The module is equipped with a jumper (JP1).
This jumper selects one of the following modes of operation:
♦Single input.
♦Redundant inputs.
♦Two independant inputs.
Refer to Table A, in the Circuit Description section.
JP1 strapped 1 & 2
♦Single Input
Connect one power supply to pins 35 and/or 36 or 31 and/or
32. That one power supply powers both fuse groups.
♦Redundant Inputs
Connect one power supply to pins 35 and/or 36. Connect a
second power supply to pins 31 and/or 32. Both supplies pro-
vide power to both fuse groups.

INSTALLATION
JP1 strapped 2 & 3
♦2 independent supplies
Connect one power supply to pins 35 and/or 36. This provides
power to fuse group 1 (fuses 1 through 6). Connect a second
power supply to pins 31 and/or 32. This provides power to
fuse group 2 (fuses 7 through 13).
EDGE CONNECTOR PINS
Normally, the 56-pin edge connector for the slot is prewired at
the factory. If you are going to wire the connector, refer to Fig. 3
for module PC connector pin wiring assignments.

CURRENT RATINGS
Be sure not to exceed the current ratings for each fuse. If
necessary, replace individual fuses (GMT-type only) with those
of a higher rating. The total current capacity for a group of
fuses (fuses 1-6 or 7-13) should not exceed 10 amperes.
FRONT PANEL RIVITS
A small color-coded plastic rivit above each fuse holder on the
front panel provides quick identification of the fuse ratings. The
unit is shipped with all 0.5 amp fuses and all red rivits installed.
(The red rivits indicate 0.5 amp fuses.)
Spare rivits for two other fuse ratings are shipped with the unit:
♦10 yellow rivits, to indicate 0.18 amp fuses
♦10 violet rivits, to indicate 0.25 amp fuses
Fuse ratings and their associated color codes, along with part
numbers for fuses and rivits supplied by Dantel, are listed in
Table B.

INSTALLATION
REMOVING OR REPLACING ARIVIT
To remove or replace a color-coded fuse rating rivit, follow these
steps:
♦Remove the B11-48001-01 module from the shelf and place it
on a flat surface, component side up.
♦Apply pressure to the back of the colored rivit, supporting the
front panel with equal pressure from the front-side edge (to
prevent bending it).
The rivit are force-fit, so it may be necessary to push against
the backside of the rivit with a small flat object. The rivit,
when loosened, falls out the front side of the hole in the face-
plate.
♦Fit the new color-coded rivit into the vacant opening from the
front of the front panel.
♦While supporting the front panel from the back side, push
the rivit into the opening from the front side until it becomes
firmly seated in the opening.
♦Reinstall the B11-48001-01 module in the shelf.
OPERATION
The front panel LED lights whenever a fuse blows. To deter- mine which fuse has blown, look for the one whose indicating
flag is in the UP position. Replace the blown fuse with a new
one of the same rating after the cause of the failure is corrected.
