General Safety Considerations
Installation
The 9145E is suitable for installation in Network telecommunication facilities and
locations where
the National Electric Code (NEC) applies.
Cabling
The 9145E 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 9145E 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 9145E 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 9145E AC and DC units do not incorporate a disconnect device. The plug on the power sup-
ply cord is intended to serve as the disconnect device. It is also recommended that the AC soc-
ket-outlet shall be installed near the equipment and shall be easily accessible.
The 9145E 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 9145E DC model is configured for a DC-I, Isolated DC return.
Fuses
The 9145E is equipped with internal fuses. The AC model is fused at 2A and the DC at 1.5A.
Surge Protection
The AC powered 9145E does not contain an internal Surge Protective Device. An external Surge
Protective Device (SPD) should be used at the AC input of the network equipment according to
facilities procedures and as defined by the National Electric Code (NEC).
