Wiring and Safety
Guidelines Use publication NFPA 70E, Electrical Safety Requirements for
Employee Workplaces when wiring the PanelView Plus terminals. In
addition to the NFPA guidelines:
•
connect the terminal 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 Amps.
•
route incoming power to the terminal by a separate path from
the communication lines.
•
where power and communication lines must cross, they should
cross at right angles.Communication lines can be installed in the
same conduit as low level DC I/O lines (less than 10 volts).
•
shield and ground cables appropriately to avoid Electromagnetic
Interference (EMI). Grounding minimizes noise from EMI and is
a safety measure in electrical installations.
For additional grounding recommendations, refer to the National
Electrical Code published by the National Fire Protection Association
of Boston.
