Wiring
Overview
The type of wiring used depends on the type of media cards being used in the system. The only
time the motherboard terminals are used is when wired media cards are plugged into the daughter
card. Otherwise, modem and fiber connections are made straight to and from the media cards.
General Guidelines
Make sure these guidelines are accounted for before wiring:

All wires must be 18 AWG, or as the local code dictates.
Conductors must test free of all grounds.
All wiring must be done using copper conductors only, unless noted otherwise.
If shielded wire is used,
- the metallic continuity of the shield must be maintained throughout the entire cable
length.
- the entire length of the cable must have a resistance greater than 1 Megohm to earth
ground.
Underground wiring must be free of all water.
In areas of high lightning activity, or in areas that have large power surges, the
2081-9027 Transient Suppressor should be used on monitor points.
Wires must not be run through elevator shafts.
Wires that run in plenum must be in conduit.
Splicing is permitted. All spliced connections must either be soldered (resin-core solder),
crimped in metal sleeves, or encapsulated with an epoxy resin. When soldering or
crimped metal sleeves are used, the junction must be insulated with a high-grade
electrical tape that is as sound as the original insulating jacket. Shield continuity must be
maintained throughout.
A system ground must be provided for earth detection and lightning protection devices.
This connection must comply with approved earth detection per NFPA780.
Only system wiring can be run together in the same conduit.
