Industrial Computers for Hazardous Locations
European Union Directive
This computer meets the European Union Directive requirements when installed within the
European Union or EEA regions and have the CE marking. A copy of the declaration of the
conformity is available at
To comply with EN 55024 and EN 55032, use the following for cable types.
Outdoor Installation
When you use a 6181X integrated display computer outdoors, consider the following to maximize
the field life of the front bezel and display:
• Select the proper enclosure
• Computer orientation
Ultraviolet (UV) and infrared radiation can reduce the field life of any electronic device. While the
materials used in the computer bezels provide long field life, that life can be improved by proper
installation. UV radiation from the sun causes all plastics to fade or yellow and become brittle over
time. Avoiding long-term exposure to direct sunlight helps protect the front of the computer from
direct exposure to UV radiation, and greatly increase its field life.
Rockwell Automation sells a sun shield (Cat. No. 6189X-SUNSHIELD) for the 6181X integrated
display computers. If you install a sun shield that closes over the display, the temperature between the
sun shield and the display cannot exceed the maximum temperature of the display, which is 55 °C
(131 °F). Adequately ventilate all sun shields to help prevent excess heat rise on the computer display.
Use stirring fans or active cooling in high altitude and high ambient temperature locations to keep
the internal enclosure temperature below 70 °C (158 °F). Use a heater in installations where the
ambient temperature is below -20 °C (-4 °F).
If possible, avoid placing the computer on the south (north in the southern hemisphere) or west side
of the cabinet. This reduces the heat rise due to solar loading during the hottest part of the day.
Mount the computer vertically to minimize solar loading on the display. Do not mount the computer
in a sloped enclosure if it exposes the computer to direct sunlight.
ATTENTION:
To comply with EN 55024 and EN 55032, the following applies to cable usage:
• USB cables must be less than 3 m (9.84 ft) long
• All I/O cables, except for Ethernet cables, must be used indoors
• All I/O cables, except for Ethernet cables, cannot exit the building at any point and cannot
directly connect to cables outside the building
