2.1 Intrinsic Safety Specification
Intrinsic safety is important in environments where flammable substances (gases or solid particles) may
exist. Two variants of the Spider AT 3000 series product line are certified for use in Intrinsically Safe
environments. These products include unique labels which identify to the interested parties what
certifications are in place.
The Spider AT 3001 has been designed and tested to meet the following Intrinsic Safety Certifications: EU
Directive 94/9/EC, according to the standards EN 60079-0: 2006 and EN 60079-15: 2005, the product has
been certified for Zone 2, Category 3.
The Spider AT 3011 has been designed and tested to meet the following Intrinsic Safety Certifications: Class
I Division 1, groups C and D according to the requirements of UL913 and CSA 22.2, for use in the United
States of America and in Canada. The product is specifically marked with Exia along with other wording to
indicate to the user that this is an intrinsically safe certified device.
Warning: Do not remove or modify the labels on the Spider AT 3001 or Spider AT
3011, doing so will invalidate the intrinsic safety certification.
