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.
Wire 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
EXPLOSION HAZARD
Do not connect or disconnect equipment unless
power has been switched off and area is known to
be non-hazardous.
