For ATEX/IEC-compliant installations with the fiberglass enclosure, you must use one of these three
choices (padlock, wire seal, or screw).
For either enclosure type, you may apply tamper-evident tape to the four sensor coupling screws
and two rotation set screws to provide evidence of unauthorized sensor adjustments. The four
coupling screws also include holes through which you could attach a wire seal.
