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.
Position of the digit
Explanation
1. digit*
Protection against solids
6
Dust tight
2. digit*
Protection against humidity
6
Protected against powerful water jets
7
Protected against temporary
immersion
9k
Protected against high pressure spray
downs
*For additional digits and more detailed descriptions please refer to the
pertinent standard.
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.
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 25.

General safety instructions and dangers
The component is safe to operate. It was built according to state-of-the-art
science and technology.
Nevertheless, dangers can arise from the component, if:
•
the component is not used as intended
•
the component is used improperly
•
the component is operated under impermissible conditions
2.5.1
Principles for safe operation
Dangerous situations during operation can be avoided by safety-conscious and
proactive behaviour of the staff.
To ensure safe operation of the valve the following principles apply:
•
The Operating Instructions must be kept ready to hand at the valve's place of
use. They must be complete and in clearly legible form.
