Advisory
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, follow these 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.
WARNING: Explosion Hazard
Substitution of components may impair suitability for hazardous locations.
Do not disconnect equipment unless power has been switched off and the
area is known to be nonhazardous.
Do not connect or disconnect components unless power has been switched
off.
All wiring must comply with N.E.C. articles 501, 502, 503, and C.E.C. section
18-1J2, as appropriate.
Peripheral equipment must be suitable for the location it is used in.
