User’s Manual Pub. 0300274-01 Rev. A.0
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
(6562 feet) 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 enclosure must have
suitable flame-retardant properties to prevent or
minimize the spread of flame, complying with a
flame spread rating of 5 VA, V2, V1, V0 (or
equivalent) if non-metallic. 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.
In addition to this publication, see:
Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for
additional installation requirements.
NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of
the degrees of protection provided by different types
of enclosure.
