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).
