The cable should not pass near any source of electrical noise such as
fluorescent circuits or motor wiring. Avoid close proximity to any AC
wiring. All control/power wiring must be in conduit.
Figure 15 - The Right and Wrong Way to Run Luma-Net
• See Table 10 for recommended Wire Types
• Use RS485 compatible cable for the communications. It is recommended that a cable with 2
Twisted Pair, 24 AWG, stranded conductors be used. The spare pair is for future uses.
• Capacitance of wire shall be 12pF/ft. or less
• Nominal Impedance of wire shall be between 100-120 ohms
• A second pair (#14 AWG stranded or larger) is required for the power.
• Drain/Shields to be tied together, insulated and grounded (on one point only)!
• We strongly recommend the use of either Belden 9829 or Belden 9729 for the Luma-
Net wire runs.
The most effective way to insulate the drain/shield wire is to use a piece of heat shrink
tubing!
