IP Protection Classes
The control top T.VIS M-15 in its standard version fulfils the demands of protection class
IP66 (DIN EN 60529). Models in protection classes IP67 or IP69k (both DIN EN 60529)
are also available.
IP classes provide information about the degree of protection an electrical device
housing provides against the ingress of solids (first digit) or humidity (second digit). They
attempt to reproduce common kinds of failure and assign so-called IP codes to the
protected systems. The letters IP stand for 'International Protection' and are prefixed to
the code numbers
Digits not to be mentioned can be replaced by the letter x (e. g. IPx6). Concerning the
ingress of humidity, IPx6 includes all lower IP classes. This is, however, not the case for
the higher protection class IPx7!
If cleaning agents are used that significantly reduce the surface tension and/or if high-
pressure cleaners are used, we recommend using IP69k rated equipment as an option.
NOTE
The specified IP classes only apply if the connectors are connected correctly, if the
cable gland is properly sealed and if the control top is fitted on the valve, see chapter
“Connection“ (page 29).
