Introduction

This installation guide describes basic concepts about Division 2 hazardous areas and
provides installation guidelines for installing the Factory Mutual approved PANTHER
panel-mount terminal into hazardous environments rated as Division 2. Only PANTHER
panel-mount terminals which are factory-labeled as approved for Division 2 may be
installed into Division 2 hazardous areas. Refer to the next chapter for details of the
required data plate markings. Previous models of the PANTHER terminal which are not
factory-labeled for Division 2 compliance may not be installed into Division 2
environments. The PANTHER harsh environment terminal is NOT approved for use in
areas classified as Division 2.
Only analog load cell versions of the PANTHER panel-mount terminal have bee
approved for use in a Division 2 area. DigiTOL versions of the PANTHER panel-mount
terminal are NOT approved for use in areas classified as Division 2.
