The connection to the Master sensor is carried out through spring-
loaded terminals in the respective housing. For this, use the supplied,
confectioned cable. Solid cores as well as flexible cores with cable
end sleeves are inserted directly into the terminal openings.
In case of flexible cores without end sleeves, press the terminal from
