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 system, the product with

the highest temperature rating determines the overall

temperature code rating of a PLC system in a Class I, Division 2

location. The temperature code rating is marked on the product

label as shown.

The following warnings apply to products having CSA certification for use

in hazardous locations.

ATTENTION – Explosion Hazard:

•Substitution of components may impair suitability for Class I, Division 2.

•

Do not replace components or disconnect equipment unless power has been switched of
