Specifications
The following information describes systemwide environmental requirements and
specifications for the Advantys STB system.
Enclosure 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 and/or radiated disturbance.
All Advantys STB modules meet CE mark requirements for open equipment as
defined by EN61131-2, and should be installed in an enclosure that is designed for
specific environmental conditions and designed to prevent personal injury resulting
from access to live parts. The interior of the enclosure must be accessible only by
the use of a tool.
Requirements This equipment meets agency certification for UL, CSA, CE, FM class 1 div 2 and
ATEX. This equipment is intended for use in a Pollution Degree 2 industrial
environment, in over-voltage Category II applications (as defined in IEC publication
60664-1), at altitudes up to 2000 m (6500 ft) without derating.
Note: Special requirements apply for enclosures located in hazardous (explosive)
environments.
