Installing the Monitor Chapter 2
Environment and Enclosure
Information Review the information on enclosures and environments before installing your
monitor.
Installation Guidelines Follow these guidelines to make sure your product provides safe and reliable
service:
• The installation site must have sufficient power.
ATTENTION: Environment and Enclosure
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 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 Publication 11. Without appropriate precautions,
there may 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 recognized and
hazardous location equipment must be mounted in an enclosure that is
suitably designed or rated for those specific environmental conditions that
will be present, and designed to prevent personal injury resulting from
accessibility to live parts. UL Listed equipment need not be mounted inside
another enclosure in ordinary (nonhazardous) locations if NEMA Type and
IEC ratings are not required, but the mounting method must limit the tilt of
the product to ± 60° from vertical. Examples include an articulated arm,
table-top stand, or other means having sufficient mechanical stability. The
mounting means must be firmly attached to the supporting surface using
screws, bolts, or clamps so the monitor cannot tip.
All units ship with a
gasketed bezel to meet specified NEMA and IEC ratings only when
mounted in a panel or enclosure with an equivalent rating.
Subsequent sections of this publication may 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
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure
ATTENTION: The monitor’s AC adapter must be grounded to maintain
an electrically safe installation. Grounding the monitor itself is not
required.
To ground the AC adapter, connect the product to earth ground using the
supplied AC cord ground wire or 0.9 mm
2
(18 AWG) or larger external wire.
The ground wire should have green insulation with a yellow stripe for easy
identification.
