Figure 8: Field wiring guidelines (NAC power supply shown as reference)
• The conductors must test free of all grounds.
• A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved
earth detection per NFPA780.
• 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.
• Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together
using wire ties.
• All wiring must use copper conductors only, unless noted otherwise.
• For IDNet, shielded wire is not recommended. If shielded wires are present, cut and tape off the shield at each end in the panel
to prevent it coming into contact with other components. The metallic continuity of the shield must be maintained and insulated
throughout the entire length of the cable.
• If shielded wire is used, the metallic continuity of the shield must be maintained throughout the entire cable length, and 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.
