Electrical Installation and Cabling

Cable and Wiring Layout

The figure below shows a typical cable and wiring layout for the Wide Bank 28 DS3. Tie-down loops

are provided on the left and right side of the connector panel for tieing down cables and wires. Because

the low-speed connectors are located in the center of the panel, it is easiest to dress the low-speed cables,

Ethernet, ground, and alarm wiring toward the left side of the chassis (as viewed from rear), with the

remaining cables and power wires dressed toward the right side, as shown.

NOTE: Ferrite Cube RFI Suppressors are Carrier Access part number 010-0051.
