Approval
The concept of the Ex approval is that the central unit is not modified, and that special ATEX/
UKEx/IEC Ex-approved cables and bushings are used, and that a special Ex optics housing pair
(CD 6 Ex) is used in the hazardous zone. In addition to this an explosion protection barrier is
added before entry into the hazardous zone. An absolute condition for the approval is that
the equipment is set up according to the system drawing in section Connection diagrams
(Page 44).
The Ex-relevant ingress protection (IP65) comprises the entire area marked with a dashed line
in the following figure.
