Chapter 2 Installing the Terminal
Environment and Enclosure
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.
The terminals are intended for use with programmable logic
controllers. Terminals that are AC powered must also be
connected to the secondary of an isolating transformer.
This equipment is considered Group 1, Class A industrial
equipment according to IEC CISPR 11. Without appropriate
precautions, there may be difficulties ensuring electromagnetic
compatibility in residential and other environments due to
conducted or radiated disturbances.
This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The interior of the enclosure must be
accessible only by the use of a tool. The terminals meet
specified NEMA Type and IEC ratings only when mounted in a
panel or enclosure with the 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:

Industrial Automation Wiring and Grounding Guidelines,
, 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.
