General Safety Considerations
Installation
The 9145EMP is suitable for installation in Network telecommunication facilities and locations
where the National Electric Code (NEC) applies.
Cabling
The 9145EMP 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 9145EMP 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 9145EMP 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 9145EMP 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 9145EMP 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 refe-
rences American National Standards Institute (ANSI) T1.315, Table 1. Additionally, Canoga Per-
kins design allows for a minimal steady state of -36VDC.
The 9145EMP DC model is configured for a DC-I, Isolated DC return.
Fuses
The 9145EMP is equipped with internal fuses. The AC model is fused at 2A and the 48VDC
model at 3.0A. 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 48VDC input voltages.
