NLEB
(Power Bay) and Model 801
NL
-
B
(Distribution Bay): Compliance verified by a Nationally
Recognized Testing Laboratory (NRTL) per GR-1089-CORE and GR-63-CORE. Contact Vertiv for NEBS
compliance reports.
(B)
Model 801
NLDB
(Power Bay) (Lists 0B, 05, 13, 21, 50, 63, 64, 65, 66, 67, 70, 71): Compliance verified by a

In order to remain compliant during a fan failure condition, the backup battery connection must be utilized to
provide sufficient power to the loads for up to eight (8) hours when the system is operated at greater than 50%
output power. If no backup battery connection is used, the system must operate with a redundant module
installed.
1.4
Local Controls and Indicators
1.4.1
"Bay Alarm" Indicator: Located at the top center of each bay.
Green = OK
Red = Bay Failure
Yellow (flashing) = Identified by the MCA
1.4.2
MCA Component Identification Indicator: Each MCA component (i.e. Rectifier Module, Bus Monitoring Circuit
Card, Bay Router Circuit Card, MCA Relay Circuit Card) contains an ID LED 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

2.1
DC Ratings
2.1.1
Bay:
6000 amperes, maximum, per bay.
16,800 amperes, maximum, per system.
2.1.2
Bus:
1500 amperes, maximum.
Each bay has four (4) Distribution Buses.
Optional Distribution Panel:
500 amperes, maximum.
One optional Distribution Panel per Distribution Bay.
2.1.3
Fuse/Circuit Breaker Mounting Positions: Each Distribution Bus contains 12 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
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.
