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:
•
connect the device and other similar electronic equipment to its
own branch circuit.
•
protect the input power by a fuse or circuit breaker rated at no
more than 15 A.
•
route incoming power to the device by a separate path from the
communication lines.
•
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.
