General Safety Considerations
Installation
The 9145ELB is suitable for installation in network telecommunication facilities and locations
where the National Electric Code (NEC) applies.
Restricted Access Location
Equipment must be installed in restricted access areas such as dedicated equipment room, or
electrical closet, in accordance with Articles 110-18, 110-26 and 110-27 of the 1999 United Sta-
tes National Electrical Code ANSI/NFPA 70.
A restricted access location is a location for equipment where both of the following apply:
1. Access can only be gained by service persons or by users who have been instructed
about the reasons for the restrictions applied to the location and about any precautions
that shall be taken; and
2. Access is through the use of a tool or lock and key, or other means of security, and is con-
trolled by the authority responsible for the location.
Do not allow conductive objects to contact the circuit board and connector that are exposed
when a module is removed (to prevent potential risk of heat and fire associated with high energy
short circuits).
Cabling
The 9145ELB has been designed and tested and has passed all the pertinent sections of
GR-1089 and GR-63 for Type 2 and Type 4 equipment. This equipment does not have direct
electrical connection to outside plant equipment.
The Copper (RJ45) ports of the 9145ELB are not intended for direct connection to “Outside
Plant” metallic conductors and must be isolated (by channel banks or office repeaters) from any
connections to network or terminal equipment that lie outside of the same building. The
telecommunication interface connections are considered to be, and meet the requirements of,
SELV circuits (not TNV).
Power
CAUTION: The 9145ELB contains a field hot swapable power supply. Before servicing
any power supply, its power supply core must be disconnected.
Wiring methods used for the connection of the equipment to the AC or DC MAINS SUPPLY must
be in accordance with the National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical
Code, Part I, CSA C22.1.
The 9145ELB DC models meet the minimal steady state operating voltage in accordance with
GR-1089, which references American National Standards Institute (ANSI) T1.315, Table 1.
