should be fitted. This ensures that the component is always operating properly
and efficiently.

IP Protection classes
The control top T.VIS M-20 FDD in its standard version fulfils the requirements of
protection class IP66, IP 67 and IP69 (DIN EN 60529) and protection class
IP6k9k (ISO 20653).
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). So-called IP codes are assigned to the protected systems. Its digits
represent common possible errors the system is protected from. The code always
starts with the letter IP for “international protection”.

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!
Hint!
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 6, Page 28.
