Wiring and Safety Guidelines
Install the InView display conforming to NFPA 70E, Electrical Safety Requirements
for Employee Workplaces. In addition to the NFPA general guidelines, refer to the
following:
Careful cable routing helps minimize electrical noise. Route incoming power to the
module by a separate path from the communication cables.
Where communication and wire paths must cross, make their intersection
perpendicular.
Grounding helps limit the effects of noise due to electromagnetic interference
(EMI). To avoid problems caused by EMI, properly ground all equipment and use
shielded cables.
TIP
Do not run communications wiring and power wiring in the same conduit.
WARNING
SHOCK HAZARD
•
Maintain separation of circuits. Route the incoming power directly to the power
connection terminal block.
•
Do not run the power wiring over the logic board or optional Legacy Communication
board.
IMPORTANT
Power wiring must be in accordance with Class I, Division 2 wiring methods (Article
501-4(b) of the National Electrical Code, NFPA70) and in accordance with the local
authority having jurisdiction.
