Degree of protection
The devices fulfill all the requirements for IP 67. Compliance with the following points is mandatory
following installation in the field or servicing, in order to ensure that IP 67 protection is maintained:
• The housing seals must be clean and undamaged when inserted into their grooves. The seals must
be dried, cleaned or replaced if necessary.
• All threaded fasteners and screw covers must be firmly tightened.
• The cables used for connection must be of the specified outside diameter (see Page 95).
• Firmly tighten the cable entries (Fig. 21).
• The cables must loop down before they enter the cable entries (“water trap”, Fig. 21). This arran-
gement prevents moisture penetrating the entry. Always install the measuring device in such a
way that the cable entries do not point up.
• Remove all unused cable entries and insert plugs instead.
• Do not remove the grommet from the cable entry.
