Outdoor Installation
When using the high-bright display module, catalog number 2711P-RDT12H, outdoors,
considerations in maximizing the field life of the front bezel and display are the following:
• Selecting the proper enclosure
• Orientation of the terminal
Both ultraviolet and infrared radiation can reduce the field life of any electronic device. While
the materials used in the terminal bezels provide long field life, that life can be improved by
proper installation.
Ultraviolet (UV) radiation from the sun causes all plastics to fade or yellow and become brittle
over time. Using an antiglare overlay, catalog number 2711P-RGT12, will protect the front of
the terminal from direct exposure to UV radiation and greatly increase its field life.
When installing the high-bright display module in an environment where the front of the
terminal will be in direct sunlight during the hottest part of the day and the external ambient
temperature can exceed 40 °C (104 °F), use the visor kit, catalog number 2711P-RVT12. The
visor reduces the solar load on the front of the display and helps to maintain internal
temperatures within specification.
ATTENTION:
This equipment is intended for use in a Pollution Degree 2 industrial environment, in
overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to
2000 m (6561 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions, there may be potential difficulties ensuring
electromagnetic compatibility in other environments due to conducted as well as radiated
disturbance.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure that
is suitably designed for those specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from accessibility to live parts. The
interior of the enclosure must be accessible only by the use of a tool. The terminals meet specified
NEMA Type and IEC ratings only when mounted in as panel or enclosure with the equivalent rating.
Subsequent sections of this publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements, Allen-Bradley publication
1770-4.1
.
• NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.
