Connection fitting
The connection fitting is the interface between the Overfill Prevention Sensor and tank truck.
Depending on the method used to fill the tank, different connection fittings are used for the
connection to the Overfill Prevention Sensor:
pipe fitting
and
wall fitting
. The connection fitting
can also be equipped with a security system (COP/FHS, see following chapters).
3.5.1
Pipe fitting
If the supply connection and the Overfill Prevention Sensor are located in the manhole, the
connection fitting for the Overfill Prevention Sensor is to be a pipe fitting.

3.5.2
Wall fitting
If the supply connection is at a distance from the tank (e.g. in a remote filling pit), the Overfill
Prevention Sensor with junction box and wall fitting is used. The connection between junction
box and wall fitting must be installed with a cable/wire of 2 x 1 mm² with a maximum length of
150 m. In the case of 2 x 1.5 mm² cables, the maximum length is 250 m.
