Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installation in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval.
WARNING
Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion,
and area re‐classification.
Note
This information supplements the nameplate markings affixed to the product.
Always refer to the nameplate itself to identify the appropriate certification. Contact your Emerson Process Management sales
office for approval/certification information not listed here.
