1.2.9 Audible Noise: The audible noise does not exceed the following when measured at
any point two feet from any vertical surface of a Power/Distribution Bay and five feet
from the floor using a Sound Level Meter conforming to ANSI S1.4.
No. of
Rectifiers
Audible Noise
1 65 dBA
10 75 dBA
1.2.10 EMI/RFI Suppression: Rectifiers operating in a Power/Distribution Bay conform to the
requirements of FCC rules Part 15, Subpart B, Class A for Radiated and Conducted emissions
limits.
1.2.11 Surge Protection
(A) Standard: Compliance with EN61000-4-5 Installation Class 4, and capable of
withstanding surges per ANSI/IEEE C 62.41-1991 Category B across the input terminals.
Note: This level of protection is a widely used standard for telecommunications power
equipment. As with all such equipment, it is the end user's responsibility to provide
an adequately sized Surge Suppression Device at the commercial power service
entrance of the building that reduces all incoming surges to levels below the
classes/categories stated for the equipment.
(B) When Equipped with List 35, 36, 37, or 38: Compliance with EN61000-4-5 Installation
Class 4, and capable of withstanding surges per ANSI/IEEE C62.41-1991 Category A,
Category B, and Category C, and ANSI/IEEE C62.41.2 Scenario II, Exposure 3, 100KA
8/20us, 10KA 10/350us.
1.2.12 ESD Protection: Complies with EN61000-4-2 Level 4 (8kV contact).
1.2.13 Electrical Fast Transient / Burst Immunity: Complies with EN61000-4-4 Level 4.
1.2.14 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) Power/Distribution Bay and Distribution Only Bay: This power
board is UL Listed ("c UL") as a DC Power Distribution Center for Communications Equipment.
This unit meets the requirements of CSA 22.2, No. 225 and is tested and Certified by UL ("c
UL") as a Custom Built Power Distribution Center for Communications Equipment.
(B) Power Only 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.
1.3.2 NEBS Compliance: 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, Bus
Monitoring Circuit Card, Bay Router Circuit Card, MCA Relay Circuit Card) contains an ID LED
