Harsh Enclosure IDNet Bracket

Note that for harsh enclosures that include an IDNet scale interface, a bracket (included with unit)
must be installed to protect the connector from a direct impact. This bracket must remain intact to
properly protect the IDNet connector and maintain the ATEX and IECEx approvals. Refer to Figure
2-7 for an example of the IDNet bracket installed on an ATEX certified IND570xx.
