Note
Note (General)The opening and closing functions depend on the direction of actuation, the actuating magnets and the polarity of the actuating magnets.When the switches and actuators come together, the colours must coincide: Red (S) to red (S) and green (N) to green (N).
The details and data referred to have been carefully checked. Images may diverge from original. Further technical data can be found in the manual. Technical amendments and errors possible.
