Installation Guidelines
• To prevent moisture from entering system, the front of the display
must be in close contact with the opening in the enclosure.
• Within every custom enclosure, the Electronics Box Back Cover
MUST remain installed because it helps dissipate the heat
generated by the CPU.
• Adequate ventilation must be provided in every custom enclosure.
The maximum allowable ambient temperature within any
enclosure is 45
o
C (113
o
F).
• To prevent accidental shorts, the power supply and any other
peripherals within the enclosure must be mounted securely and
within reach of the display’s connectors.

381 mm (15 in.) cable. When using the motion sensor, it must be
mounted between 25 and 76 mm (1 to 3 in.) below the bottom of the

includes a front enclosure in which the motion sensor is already
mounted.)
