ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC 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 22. Without appropriate precautions, there can be potential
difficulties with electromagnetic compatibility in other environments due to
conducted and radiated disturbance.
This equipment is supplied as open type equipment. The interior of the
enclosure must be accessible only by the use of a tool. UL Listed equipment need
not be mounted inside another enclosure. Subsequent sections of this
publication can contain extra information about specific enclosure type ratings
that are required to comply with certain product safety certifications.
In addition to this publication, see the following:

4.1 , for additional installation requirements
• NEMA 250 and IEC 60529, as applicable, for explanations of the degrees of
protection that are provided by different types of enclosure
ATTENTION: This computer is intended to operate in an industrial or control
room environment, which uses some form of power isolation from the public
low–voltage mains. Some computer configurations cannot comply with the
EN 61000-3-2 Harmonic Emissions standard as specified by the EMC
Directive of the European Union. Obtain permission from the local power
authority before you connect any computer configuration that draws more
than 75 W of AC power directly from the public mains.
To comply with EN 55024, the Ethernet port LAN cable must be only used
