3.1. Enclosure
Only IND570xx terminals that are factory-labeled as Division 2 approved may be installed into a
Division 2 area. Similarly, only IND570xx terminals that are factory-labeled as Category 3 or zone
2/22 approved may be installed into a Zone 2 or Zone 22 hazardous area.
Also note that a dust tight enclosure is required for proper installation of the panel-mount terminal in
the U.S. and Canada. This note is on the METTLER TOLEDO control drawing 30116036.
The ATEX and IECEx certificates issued by FM requires the use of increased safety "e" glands and
blanks on the IND570xx harsh enclosure. An ATEX certified enclosure with a minimum ingress
protection rating of IP65 is required for panel-mount installation in Europe. An IECEx certified
enclosure with a minimum ingress protection rating of IP65 is required for panel-mount installation
according to the IECEx approval.
3.2. Areas with Different Classifications
The IND570xx terminal has been approved for use in an area classified as Division 2 or as Zone 2
or Zone 22. This approval DOES NOT mean that the IND570xx terminal can be used in Division 1,
Zone 0/1 or Zone 20/21 areas. Different precautions must be taken when installing equipment into
these areas. METTLER TOLEDO offers other terminals for use in Division 1, Zone 0/1 or Zone 20/21
areas.
If any portion of the installation involves an area classified as Division 1, Zone 0/1 or Zone 20/21,
then the complete system should be configured to be compatible with a Division 1, Zone 0/1 or
Zone 20/21 classification. For instance, if the IND570xx terminal will be installed in a Division 2

When an IND570xx terminal is installed inside an area classified as Division 2
or Zone 2/22, some special requirements must be considered. This chapter
discusses these items. The METTLER TOLEDO control drawing 30116036,
installation drawing 30116037 and the cFMus, ATEX and IECEx approval
certificates must also be reviewed for any special requirements.
VERSIONS OF THE IND570 TERMINAL THAT ARE NOT LABELED AS DIVISION 2 OR ZONE 2/22
APPROVED MUST NOT BE INSTALLED IN A DIVISION 2 OR ZONE 2/22 ENVIRONMENT.
