Indicator. The ID indicator illuminates Green when the component is OK, Red when
the component has failed, and flashing yellow when the component is identified by the
MCA.
1.4.3 "Distribution Bus" Indicators: Each distribution bus contains and indicator located on a
hinged door panel covering the bus's MCA Monitoring circuit card.
Green = OK
Red = Card Failure
Yellow (flashing) = Identified by the MCA
1.4.4 See also specifications for Rectifier, MCA, and LMS.
2. DC DISTRIBUTION
2.1 Ratings
2.1.1 Power/Distribution Bay
(A) Power/Distribution Bay: 2400 amperes, maximum, per bay.
10,000 amperes, maximum, per system.
(B) Distribution Bus: 1200 amperes, maximum.
Each Power/Distribution Bay has two (2) Distribution Buses.
(C) Fuse/Circuit Breaker Mounting Positions: Each Distribution Bus contains 24 fuse/circuit
breaker mounting positions which provides 48 fuse/circuit breaker mounting positions per
bay. Note that some fuse/circuit breaker combinations require more than one fuse/circuit
breaker mounting position. Refer to Distribution Devices under ACCESSORY
DESCRIPTIONS for details.
2.1.2 Distribution Only Bay
(A) Distribution Only Bay: 6000 amperes, maximum, per bay.
10,000 amperes, maximum, per system.
(B) Distribution Bus: 1500 amperes, maximum.
Each bay has four (4) Distribution Buses.
(C) Optional Distribution Panel: 500 amperes, maximum.
One optional Distribution Panel per Distribution Bay.
(D) Fuse/Circuit Breaker Mounting Positions: Each Distribution Bus contains 12 fuse/circuit
breaker mounting positions which provide 48 fuse/circuit breaker mounting positions per
bay. Note that some fuse/circuit breaker combinations require more than one fuse/circuit
breaker mounting position. Refer to Distribution Devices under ACCESSORY
DESCRIPTIONS for details.
The optional Distribution Panel provides twenty-four (24) Bullet Nose Device positions.
The panel accepts a choice of TLS/TPS-type fuseholders or Bullet Nose-type circuit
breakers. When installed, bay can be loaded with up to (46) 218 Circuit Breakers or TPL
Fuses, and (24) Bullet Nose Circuit Breakers or TLS/TPS Fuses.
Note: The List C Circuit Breaker/Fuse Panel requires distribution position #12 in the Bus #1
Distribution Panel. Also, distribution position #36 in the Bus #3 Distribution Panel must
remain empty.
3. RECTIFIER
3.1 Output Ratings
3.1.1 Voltage: Nominal -48 volts DC, Positive Ground.
(A) Without Battery Charge Temperature Compensation: Float voltage is adjustable from
47.00 to 58.00 volts DC. Test/equalize voltage is adjustable from 45.00 to 58.00 volts DC.
Both float and test/equalize voltages are factory set at 52.00 volts, unless otherwise
specified. The output voltage temperature coefficient does not exceed 0.01% per degree
centigrade from 0°C to +40°C.
(B) With Battery Charge Digital Temperature Compensation Probe: With an optional
battery charge digital temperature compensation probe installed, the MCA automatically
