Chapter 1
Introduction
This installation guide describes some basic concepts about Division 2 and Zone
2/22 hazardous areas and provides guidelines for installing the UL and DEMKO
approved IND780 terminal into hazardous environments rated as Division 2 or
Zone 2/22. Only IND780 terminals that are factory-labeled as Division 2 approved
or marked as Category 3 may be installed into a Division 2 or Zone 2/22
hazardous area. Refer to the next chapter for details of the data plate markings on
approved terminals. Models of the IND780 terminal that are not factory labeled for
Division 2 compliance or as Category 3 devices may not be installed into a
Division 2 or Zone 2/22 environment.
The approval by Underwriters Laboratories (UL) applies to Division 2 or Zone 2
applications that require certification to the appropriate United States and Canadian
standards (see below). The ATEX certification applies to European Zone 2/22
applications that require certification to CENELEC standards to the ATEX directive.
UL has also issued an IECEx Certificate of Conformity to appropriate IEC standards.
These approvals may also be acceptable in other worldwide locations. Confirm
with the customer or with local authorities the acceptance of these approvals before
installation. Regardless of the installation location, all local and national wiring
and installation requirements must be followed during installation.
The IND780 is certified to the following standards:
