CSA Hazardous Location Approval

CSA certifies products for general use as well as for use in hazardous locations. Actual CSA certification is
indicated by the product label as shown below, and not by statements in any user documentation.
Example of the CSA certification product label
To comply with CSA certification for use in hazardous locations, the following information
becomes a part of the product literature for CSA-certified Allen-Bradley industrial control
products.
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D, or
non-hazardous locations only.
The products having the appropriate CSA markings (that is, Class I Division 2, Groups A, B,
C, D), are certified for use in other equipment where the suitability of combination (that is,
application or use) is determined by the CSA or the local inspection office having jurisdiction.
Important: Due to the modular nature of a PLC control system, the product with the highest
temperature rating determines the overall temperature code rating of a PLC control system in a
Class I, Division 2 location. The temperature code rating is marked on the product label as
shown.
