hazardous environment
An AADvance system must be installed in a suitable enclosure to maintain a
Pollution Degree 2 (IEC 60664-1) environment. When used in an ATEX Zone 2
atmosphere the enclosure must provide a minimum ingress rating of IP54.
Pollution Degree
The IEC definition of the four pollution degrees are given in IEC 60664-1:2007: For the
purpose of evaluating creepage distances and clearances, the following four degrees of
pollution in the micro-environment are established:
 Pollution Degree 1: No pollution or only dry pollution occurs. The pollution has
no influence.
 Pollution Degree 2: Only non-conductive pollution occurs except that occasionally
a temporary conductivity caused by condensation is to be expected.
 Pollution Degree 3: Conductive pollution occurs or dry non-conductive pollution
occurs which becomes conductive due to condensation which is to be expected.
 Pollution Degree 4: Continuous conductivity occurs due to conductive dust, rain
or other wet conditions.
CAUTION STATIC SENSITIVE COMPONENTS
The controller contains static sensitive devices which can be damaged by
incorrect handling. You should label the exterior surfaces of the enclosure to
caution personnel to observe antistatic precautions when handling modules.

Enclosure Requirements for a Hazardous Environment
For a system that is located in a Zone 2 Hazardous environment where ATEX
certification is required, all modules should be installed in an ATEX and IECEx
Certified, tool accessible IP54 enclosure that has been evaluated to the requirements
of IEC 60079-0:2009 and IEC 60079-15:2010. The enclosure is to be marked with the
following: "Warning - Do not open when energized". After installation of the modules
into the enclosure, the enclosure should provide sufficient access and space so that the
field wiring conductors can easily be connected. It is also recommended that potted
glands or equivalent are used when the cable runs into other zoned areas to prevent
the propagation of explosive gasses from an external atmosphere through the cable
sleeving. Modules are for use in an area of not more than pollution degree 2 in
accordance with IEC 60664-1.
This equipment is not certified for use in a Zone 1 location. In a Zone 1 hazardous
environment the equipment should be housed in an enclosure offering suitable
additional protection. This enclosure should be certified to IEC 60079-0:2009 and IEC
60079-1:2007.
This equipment is not certified for use in a Zone 0 hazardous environment.
