Wiring and Safety
Guidelines
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.
Route communication cables to terminal by a separate path from
incoming power.
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.
IMPORTANT
Do not run signal wiring and power wiring in the
same conduit.
