Note
Environment and Enclosure Guidelines
Review these environmental and enclosure guidelines before installation:
• 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 9842 ft (3 km) 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 nonmetallic. The interior of the enclosure
must be accessible only by the use of a tool. Subsequent sections of this publication might contain
additional information regarding specific enclosure-type ratings that are required to comply with certain
product safety certifications.
