Wiring and Safety
Guidelines
Use publication NFPA 70E, Electrical Safety Requirements for
Employee Workplaces when wiring the PanelView terminals. In
addition to the NFPA general guidelines:
route communication cables to terminal by a separate path from
incoming power.
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).
grounding minimizes noise from Electromagnetic Interference
(EMI) and is a safety measure in electrical installations.
use the National Electric Code published by the National Fire
Protection Association as a source for grounding.
IMPORTANT
Do not run signal wiring and power wiring in the
same conduit.
