General Safety Considerations
Installation
The 9145E10G is suitable for installation in Network telecommunication facilities and
locations
where the National Electric Code (NEC) applies.
Cabling
The 9145E10G 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 electri-
cal connection to outside plant equipment.
The Copper (RJ45) ports of the 9145E10G are not intended for direct connection to “Outside
Plant” metallic conductors and shall be isolated (by channel banks or office repeaters) from any
connections to network or terminal equipment that lie outside of the same building. The telecom-
munication interface connections are considered to be, and meet the requirements of, SELV cir-
cuits (not TNV).
Power
WARNING: The 9145E10G with redundant power supplies must have both power supply
cords disconnected before servicing.
Wiring methods used for the connection of the equipment to the AC or DC MAINS SUPPLY shall
be in accordance with the National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical
Code, Part I, CSA C22.1.
The 9145E10G AC and DC units do not incorporate a disconnect device. The plug on the power
supply cord is intended to serve as the disconnect device. It is also recommended that the AC
socket-outlet shall be installed near the equipment and shall be easily accessible.
The 9145E10G DC has a nominal operating DC voltage of -48 VDC and passes the minimal
steady state DC operating voltage of -40 VDC in accordance with GR-1089 Issue 4 which
references American National Standards Institute (ANSI) T1.315, Table 1. Additionally, Canoga
Perkins design allows for a minimal steady state of -36VDC.
The 9145E10G DC model is configured for a DC-I, Isolated DC return.
Fuses
The 9145E10G is equipped with internal fuses. The AC model is fused at 2A, and the 24VDC
and the 48VDC models at 3A. Although not required, an external fuse may be used to isolate the
unit in a shared fuse distribution panel. In that case, the unit should be fused with a 3A slow blow
fuse or a 5A fast acting fuse for either 24VDC or 48VDC input voltages.
