7.1
Replace the protective caps with suitably certified and temperature rated cable glands and blanking plugs permitted for use
with ATEX/IECEx flameproof enclosures.
7.2
Product IP rating is ensured only by the use of suitable IP rated cable glands and plugs
7.3
Make sure that the cable glands are steadily tightened so that the sealing ring reaches the proper compression to avoid the
transmission of mechanical stresses to the terminals (4).
7.4
Number, position and size of the provided cable entries are specified in the adhesive label outside the box cover. Number and
type of cable entries can also be determined by reference to the 4th digit of limit switch box model marked on both internal and
external labels. The certified cable entry options in the following table (3):
