General Safety Considerations
Installation
The 2240 is suitable for installation in network telecommunication facilities and locations where
the National Electric Code (NEC) applies.
Cabling
This equipment does not have direct electrical connection to outside plant equipment.
The copper ports of the 2240 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 telecommunication
interface connections are considered to be, and meet the requirements of, SELV circuits (not
TNV).
Power
WARNING: The 2240 installed in a 2201 Chassis 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 2240 Stand Alone 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.
Fuses
The 2240 stand alone is not equipped with internal fuses. The 2201 Chassis is fused at 2A Slow
Blow.
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.
Surge Protection
The 2240 does not contain an internal Surge Protective Device (SPD). An external SPD should
be used at the AC input of the network equipment according to facilities procedures and as
defined by the NEC.
