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 in the example below, and not by statements in any user
documentation.

CLASS 1, GROUPS A, B, C AND D, DIV. 2

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 off and the area is known to
be non-hazardous.

Do not connect or disconnect while circuit is live unless area is known to be non-hazardous.

Do not disconnect connectors unless power has been switched off or the area is known to be non-hazardous.
Secure any user-supplied connectors that mate to external circuits on an Allen-Bradley product using screws,
sliding latches, threaded connectors, or other means such that any connection can withstand a 15 Newton (3.4 lb.)
separating force applied for a minimum of one minute.
