Residual-current device (RCD)
This pump is equipped with a frequency converter. This means it may not be protec-
ted by a residual-current device.
Frequency converters can impair the functioning of
residual current-operated protection circuits.
Exception: residual-current devices which have a selective type B universal current-
sensitive design are allowed:

6.7.2 Electromagnetic compatibility
The IEC 61000-3-12 standard regulates the connection to the public low voltage sup-
ply network.
Pumps in efficiency classes 11 ... 22 kW are devices for professional use. They are sub-
ject to special connection conditions, as an R
SCE
of 33 at the connection point is insuffi-
cient to operate them. The pumps have been assessed based on table 4 of the standard
(“three-phase devices under special conditions”).
Pumps in efficiency classes 11 ... 22 kW only comply with the standard IEC
61000-3-12:2011 if the following condition is met at all public connection points:
ƒ
At the interface between the electrical installation of the user and the public power
supply network, the short-circuit power S

must be greater than or equal to the val-
ues listed in the following table!
