SPECIFICATIONS
1.1 DC Operating Voltage
1.1.1 Nominal: -48Vdc.
1.1.2 Range: -42Vdc to -60Vdc.
1.2 Environmental Ratings
1.2.1 Operating Ambient Temperature Range: 0°C to +40°C (+32°F to +104°F).
1.2.2 Storage Ambient Temperature Range: -40°C to +80°C (-40°F to +176°F).
1.2.3 Humidity: This system is capable of operating in an ambient relative humidity range of 0% to
95%, non-condensing.
1.2.4 Altitude: The maximum operating ambient temperature should be de-rated by 10°C at an
elevation of 10,000 feet above sea level. For elevations between 3,000 feet and 10,000 feet,
derate the maximum operating ambient temperature linearly.
1.2.5 Mounting: This product 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.
This BDF/CBB uses natural convection. Equipment designed for use in environmentally
controlled space.
This product is intended for installation in Network Telecommunication Facilities (CO, vault,
hut, or other environmentally controlled electronic equipment enclosure).
This product is intended to be connected to the common bonding network in a Network
Telecommunication Facility (CO, vault, hut, or other environmentally controlled electronic
equipment enclosure).
1.3 Compliance Information
1.3.1 Safety Compliance: This BDF/CBB is UL Listed (and "cULus") as a DC Power Distribution
Center for Communications 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.
