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
publication 60664-1), at altitudes up to 2000 m (6562 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. 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 5VA, 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, for
additional installation requirements, Allen-Bradley 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.
