Wiring guidelines
Follow these guidelines when connecting power-limited (PL) systems. For more information about these guidelines, contact your authorized Simplex
product supplier.
• Non-power limited (NPL) field wiring (AC power, batteries, City connection, DACT) must be installed and routed in the shaded areas shown in Figure 6:
Field wiring guidelines (NAC power supply shown as reference) on page 8
• You must maintain a minimum of 0.25 in. (6.35 mm) space between NPL and PL field wiring.
• The AC harness is pre-wired and tied to back of the box.
Fig 6: 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.
