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.

Changing the Serial
Address
A serial address for an InView sign is a number from 1 to 254 in
hexadecimal (01 to FE). All signs leave the factory with a default
address of 1 or 01.
The serial address is set in the messaging software and downloaded to
the display with the InView applications.
Checkout Procedure
After installing a sign according to the Electrical and Mounting
Instructions, make sure the sign is installed properly by applying
power to it. The following information should be displayed on the
sign:
•firmware part number and version letter (e.g., xxxx),
•amount of RAM in the sign, (e.g., 256K), and
•serial address of the sign (a number from 01 to FE or from 1 to
254).

Connecting the power wires
1. Remove the power supply cover by unscrewing its 6 screws.
Save the screws for a later step.
2. It is recommended that you install power and serial wires at the
bottom of the power supply enclosure. However, to
accommodate power or serial wire installation at the top of the
enclosure, you may want to remove the left or right conduit hole
plug from the top of the enclosure by removing its wing nut
inside the enclosure. Save the hole plug for a later step.
ATTENTION
!
Hazardous voltage. Contact with high voltage may
cause death or serious injury. Always disconnect
power to sign prior to servicing.

3. Insert the power wires through the left conduit hole on either
the top or the bottom of the sign. The bottom conduit hole is
recommended to reduce noise from power wires crossing serial
wires.
4. Strip the wires back 1/4”. Connect the incoming electrical wires.
Be sure to place the wires so they are not caught by screws
when replacing the power supply cover, and also so they do not
interfere with fan operation.
5. Insert the serial wires through the right conduit hole on either
the top or the bottom of the sign.
TIP Use watertight conduit connectors only.
Flexible conduit should be used.

so the bracket fits in the indentation. There are left and right
ceiling brackets. Use the one that fits with the screw hole’s
countersunk side facing out. Secure the ceiling bracket with the
screw removed in Step 1. Torque the screws to 2.7 Nm
(24 in-lb).
3. Repeat steps 1 and 2 for the other end of the sign.
4. Use chains (not supplied) to hang the sign from a ceiling.

the end caps, following Steps 1 to 4 of the Wall mounting
instructions. However, replace only the bottom three screws for
each end cap. Torque the screws to 2.7 Nm (24 in-lb). Do this
step for each end of both signs.

Temperature Protection in
NEMA-Rated Enclosures
InView P42, P43, P44, P72, and P74 signs have automatic temperature
controls that help to protect the sign from damage when the internal
temperature of the sign is too hot to continue normal operation.
•If the internal temperature of the sign reaches a pre-determined
“dimming point”, the LED output from the sign is forced into a
50 percent reduced power mode, effectively dimming the
brightness of LED output by about 50 percent.
•If the internal temperature of the sign continues to increase,
another sensing circuit will execute an automatic shut down to
protect the sign from damage. The LED output from the sign is
turned off.
•The dimming and shutdown points are listed in the table below.
Once the temperature drops below the auto-shutdown
threshold, the LED output is turned on at the dimming level.
Once the temperature drops below the dimming threshold,
auto-dimming is disabled and the LED brightness is back to 100
percent.

TIP Take into account the effects of ambient temperature
when evaluating mounting locations for the sign.
You should always maintain recommended clearance
distances around the sign and avoid poorly
ventilated mounting locations that could be subject
to radiation, convection, conduction or other thermal
transfer effects.
