Division 2, Groups A, B, C, D or non-hazardous locations only. Each product
is supplied with markings on the rating nameplate indicating the hazardous
location temperature code. When combining products within a system, the
most adverse temperature code (lowest “T” number) may be used to help

equipment in your system are subject to investigation by the local authority
having jurisdiction at the time of installation.
