5.3 Degree of protection
The devices fulfill all the requirements for IP 67 degree of protection. Compliance with the
following points is mandatory following installation or servicing in order to ensure that IP 67
protection is maintained:
• The housing seal must be clean and undamaged when inserted into the seal groove. The
seal may have to be cleaned, dried or replaced.
• The cables used for connection must be of the correct specified outside diameter (e.g. M20 x
1.5, Kabeldurchmesser 8 to 12 mm (0.3 to 0.47 in)). Install the device upright in such a way
that the cable entries point downwards.
• The cables must loop down before they enter the cable entries (→  8,  33). This
arrangement prevents moisture penetrating the entry. Install the device so that the cable
entries are not facing upwards.
• Replace any unused cable entries with dummy plugs.
• The grommet used should not be removed from the cable entry.
• The housing cover and the cable entry must be well tightened.
