1.2.11 Electrical Fast Transient / Burst Immunity: Complies with EN61000-4-4 Level 4.
1.2.12 Mounting: This Power System is intended only for installation in a Restricted Access
Location on or above a non-combustible surface. Typical industry standards recommend
minimum aisle space clearance of 2'6" for the front of the relay rack and 2' for the rear of the
relay rack.
1.3 Compliance Information
1.3.1 Safety Compliance
(A) Model 801
NLEB and 801NLDB (Power Bay): This unit meets the requirements of UL 60950,
Standard for Information Technology Equipment, and is UL Listed as a power supply for use
in Telephone, Electronic Data Processing or Information Processing Equipment.
(B) Model 801
NL-B (Distribution Bay): This power board is UL Listed as a DC Power
Distribution Center for Communications Equipment.
1.3.2 NEBS Compliance
(A) Model 801
NLEB (Power Bay) and Model 801NL-B (Distribution Bay): Compliance verified
by a Nationally Recognized Testing Laboratory (NRTL) per GR-1089-CORE and
GR-63-CORE. Contact Emerson Network Power 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 Nationally Recognized Testing Laboratory (NRTL) per
GR-1089-CORE and GR-63-CORE. Contact Emerson Network Power for NEBS
compliance reports.
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 See also ‘Local Controls and Indicators’ in the Rectifier Module, MCA, and LMS sections.
