Ensuring the degree of protection

The measuring system meets all the requirements of IP67 protection. Compliance with the
following points is mandatory following installation in the field or servicing in order to ensure
that IP67 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 housing screws and screw caps must be firmly tightened.
• The cables used for connection must be of the specified outside diameter (e.g. M20x1.5,
cable diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  9,  42
• The cables must loop down before they enter the cable glands ("water trap"). This means
that any moisture that may form cannot enter the gland. Install the device so that the cable
glands are not facing upwards. →  9,  42
• Cable glands not used are to be blanked off using the dummy plugs provided.
• Do not remove the grommet from the cable gland.
