certification .
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 11. Without appropriate precautions, there can 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. UL Listed equipment need not
be mounted inside another enclosure. Subsequent sections of this publication can
contain additional information regarding specific enclosure type ratings that are
required to comply with certain product safety certifications.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1 ,
for additional installation requirements
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of the
degrees of protection 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
connecting 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 less than 30 m
(98.42 ft), only used indoors, and not exit the building at any point. All other I/O
cables must be less than 3 m (9.84 ft) and only used indoors.
