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 that 10V).
• shield and ground cables appropriately to avoid electromagnetic
interference (EMI).
Grounding minimizes noise from EMI and is a safety measure in
electrical installation.
For more information on grounding recommendations, see the National
Electrical Code published by the National Fire Protection Association.
