ATTENTION
This equipment is intended for use 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 ‘enclosed’ equipment. It should
not require additional system enclosure when used in locations
consistent with the enclosure type ratings stated in the
Specifications section of this publication. Subsequent sections of
this publication may contain additional information regarding
specific enclosure type ratings, beyond what this product
provides, that are required to comply with certain product safety
certifications.
NOTE: 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
