The electrical data for the relay is contained in the chapter "Installation,
electrical".
Sound pressure level LpA < 70 dB according to EN ISO 20361

(With identity code specification "Version": "M" - "modified")
Technical data of pumps in the modified version can deviate from those of
the standard pumps. They can be queried by stating the details of the
serial number.
During operation with an automatic stroke length adjustment control
together with a variable speed motor, the stroke rate must not fall below
30 strokes / min. Otherwise technical problems occur, because the
mechanical resistance of the stroke adjustment spindle becomes too high.
The motor data sheets for the modified version are valid. They may
deviate from the standard motor data sheets.
With a modified version, it is absolutely necessary to specify the details of
the serial number requesting and ordering the spare and replacement
parts.
