The following statement applies to when the computer is used in a hazardous location.
Hot Surfaces
Restricted Access Location
Verify that restricted access locations for the equipment meet the following
conditions:
•
Access is gained only by service personnel or by users who have been
instructed on the reasons for restrictions to a location and about any
precautions to be taken.
•
Access is by using a tool, a lock and key, or other means of security
controlled by the authority responsible for the location.
WARNING: Explosion Hazard
•
Substitution of components can impair suitability for hazardous locations.
•
Do not disconnect equipment unless power has been switched off and the area
is known to be nonhazardous.
•
Do not connect or disconnect components unless power has been switched off.
•
Peripheral equipment must be suitable for the location where it is used.
•
In the U.S., all wiring must be in accordance with Class I, Division 2 wiring methods
of Article 501 of the National Electrical Code, and in accordance with the authority
having jurisdiction. See
Control Drawing for USB Peripheral Devices on page 19
for allowable circuit parameters in Class I, Division 2 applications.
•
In Canada, all wiring must be in accordance with Section 18-1J2 of the Canadian
Electrical Code, and in accordance with the authority having jurisdiction.
•
For European Zone 2 and IECEx applications:
–
Provide transient limiting in the application that limits transient
overvoltages to not more than 40% above the applied voltage.
–
Non-display computers must be installed in a Pollution Degree 2 environment
and fully mounted within an enclosure rated IP54 minimum.
–
Do not use the USB ports unless the area is known to be nonhazardous.
•
For European Zone 2 (gases) and IECEx applications, computers with displays
must be installed in a Pollution Degree 2 environment and mounted through
the wall or door of an enclosure rated IP54 minimum.
•
For European Zone 22 (dusts) and IECEx applications, computers with displays
must be installed in a Pollution Degree 2 environment and mounted through
the wall or door of an enclosure rated IP6x minimum. Computers with displays
support enclosures rated up to IP66.
•
In final applications, properly connect these devices to ground by using the
ground terminal screw on the computer chassis.
ATTENTION:
When used above 50 °C (122 °F), the backside of display
computers and entire non-display computers must be installed in a restricted
access location.
