Use publication NFPA 70E, Electrical Safety Requirements for Employee Workplaces, IEC 60364 Electrical Installations in Buildings, or
other applicable wiring safety requirements for the country of installation when wiring the devices. In addition to the NFPA
guidelines, here are some other guidelines to follow:

• Route communication cables to terminal by a separate path from incoming power. Do not run signal wiring and power wiring in

the same conduit.

• Cross power and communication lines at right angles if they must cross.
• Communication lines can be installed in the same conduit as low-level DC I/O lines (less than 10V).
• Shield and ground cables appropriately to avoid electromagnetic interference (EMI). Grounding minimizes noise from EMI and is

a safety measure in electrical installations.

For more information on grounding recommendations, refer to the National Electrical Code published by the National Fire Protection
Association.
