Use in Hazardous Areas

Standard versions of the IND131 and IND331 terminals are not certified for use within hazardous
(explosive) areas. Specially marked terminals (models IND131xx and IND331xx) are FM and
KEMA certified for use in hazardous areas classified as Division 2 or Zone 2/22.

Inspection and Contents Checklist

Verify the contents and inspect the package immediately upon delivery. If the shipping container is
damaged, check for internal damage and file a freight claim with the carrier if necessary. If the
container is not damaged, remove the terminal from its protective package, noting how it was
packed, and inspect each component for damage.
If shipping the terminal is required, it is best to use the original shipping container. The terminal
must be packed correctly to ensure its safe transportation.
The package should include:
