Mettler Toledo Division 2 IND570 Serie Guia De Instalacion página 17

Note that, in addition to a 25mm gland, there are three 16mm glands with a smaller cable entry
hole and two with a larger cable entry hole. Make sure to choose the gland with the correct hole
size based on the cable used. To maintain the IP rating of the enclosure, the gland must tighten
securely around the cable. Table 2-3 lists the range of cable sizes that fit each gland.
For proper installation of a panel-mount IND570xx with an IDNet or SICSpro scale interface inside
an enclosure, the cable must enter the enclosure through an ATEX/IECEx certified gland. The gland
must be large enough to allow the IDNet or SICSpro connector from the base to pass through the
center and then seal tightly around the cable. This ATEX/IECEx certified gland is not provided by
METTLER TOLEDO.
The standard IND570 terminal offers options for external connectors to extend the USB port and the
Ethernet port to the outside of the enclosure. These options MUST NOT be used in the IND570xx
installation when the terminal will be located inside the Division 2 or Zone 2/22 area.
