Must be installed per document 12879. For application in explosive atmospheres caused by gases, vapours or mists and where
the use of apparatus of category 1G is required, electrostatic charges on the cable and non-metallic parts of the enclosure shall be
avoided. The ambient temperature range for these applications is -40°C to +80°C.
Note: Due to continuous process improvement, specifications are subject to change without notice. This document is cleared for public release.
