4.4 Degree of protection
The measuring device fulfills 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.
• The screws and screw covers must be firmly tightened.
• The cables used for connection must be of the specified outside diameter → ä 85, Cable entries.
• The cable entries must be firmly tightened (point a → å 15).
• The cable must loop down in front of the cable entry ("water trap")
(point b → å 15). This arrangement prevents moisture penetrating the entry.
