English Section InView Marquee Message Display
Introduction These instructions show how to change the serial address and how to
mount InView series signs with NEMA Types 4, 4X, and 12 enclosures.
These signs are intended for indoor use only. Type 4 enclosures are
intended to provide a degree of protection against windblown dust
and rain, splashing water, and hose-directed water. Type 4X
enclosures are intended to provide a degree of protection against
corrosion, windblown dust and rain, splashing water, and
hose-directed water. Type 12 enclosures are in a sealed case that is,
dust free, gasketing, and spray down resistant.
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.
Do not run communications wiring and power wiring in the
same conduit!
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.
IMPORTANT
Power wiring must be in accordance with Class I,
Class II and Class III Division 2 wiring methods
(Articles 501-4(b), 502-4(b) and 503-3(b) of the
National Electrical Code, NFPA70) and in
accordance with the local authority having
jurisdiction.
