Hazardous Area Classifications and
Special Instructions for “Safe Use”
and Installations 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.

nameplate markings affixed to the
product.
Always refer to the nameplate itself to
identify the appropriate certification.
