4 VersaView 1200P Integrated Display Computers for Hazardous Locations
Publication 6183H-IN001E-EN-P - July 2007
The following statement applies to use in hazardous locations.
The computers have a temperature code of T4 135 °C (275 °F) when operating in
50 °C (122 °F) maximum ambient temperature. Do not install the computer in
environments where the explosive atmosphere (for example, gas) has an ignition
temperature less than 135 °C (275 °F).
WARNING
Explosion Hazard
Substitution of components may impair suitability for hazardous locations.
Do not disconnect equipment unless power has been switched off and area
is known to be nonhazardous.
Do not connect or disconnect components unless power has been switched
off.
All wiring must comply with N.E.C., NFPA 70 articles 501.4(B), 505.15(C) as
appropriate and in accordance with the authority having jurisdiction.
Peripheral equipment must be suitable for the location it is used in.
For European Zone 2 and Canadian Ex applications, provisions shall be
made to prevent the rated applied voltage from being exceeded by
transient disturbances of more than 40%.
For European Zone 2 and Canadian Ex applications, non-display computers
must be mounted completely within an enclosure rated IP54 minimum.
Computers with displays must be mounted through the wall or door of an
enclosure rated IP54 minimum. Computers with displays support
enclosures rated up to IP66.
These devices shall be properly connected to ground (protective earth) in
the final application.
Refer to control drawing information in this document for allowable circuit
parameters, in Class I, Division 2 applications. Do not use the USB and PS2
ports in European Zone 2 and Canadian Ex applications unless the area is
known to be nonhazardous.
