Environment and Enclosure
ATTENTION
!
ATTENTION
!
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 meters 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. 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. Subsequent sections of this
publication may contain additional
information regarding specific enclosure
type ratings that are required to comply
with certain product safety certifications.
See NEMA Standards publication 250 and
IEC publication 60529, as applicable, for
explanations of the degrees of protection
provided by different types of enclosure.
Also, see the appropriate sections in this
publication, as well as the Allen-Bradley
publication 1770-4.1 ("Industrial Automation
Wiring and Grounding Guidelines"), for
additional installation requirements
pertaining to this equipment.
Identifies information about practices or
circumstances that can cause an explosion
in a hazardous environment, which may
lead to personal injury or death, property
damage, or economic loss.
