Chapter 2 The AADvance Safety Controller
Non-Hazardous Installation Requirements
Environmental
In a non-hazardous environment a system can be installed in an enclosure or
on a support/wall; however, the enclosure or the area where it is installed must
not be more than a Pollution Degree 2 or similar environment in accordance
with IEC 60664-1:2007.
The surrounding air temperature ratings are:
• For the T9110 Processor module = 60 °C
• For all other I/O modules, base units and termination assemblies = 60 °C
Pollution Degree Definition
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.
Installation Requirements
for Hazardous Environment
The AADvance controller has been investigated and approved by UL for use as
Industrial Control Equipment in hazardous locations, Class I, Division 2,
Groups A, B, C and D in North America.
The AADvance controller has been assessed for ATEX compliance. The UL
Certification No. is DEMKO 11 ATEX 1129711X. The ATEX marking is
Ex nA IIC T4 Gc.
Additionally the AADvance controller is approved under the IECEx
certification scheme. The certificate number is IECEx UL 12.0032X.
Installation Requirements
To comply with the standards the following conditions must be applied to the
installation:
