Warning
Danger to life due to non-tripping of the
residual current device (RCD)!
If the pump is connected to an electric
installation where a residual current
device (RCD) is used as an additional
protection, this RCD must trip when
ground fault currents with DC content
(pulsating DC) and smooth DC ground
fault currents occur. This means that a
RCD type B, sensitive to universal current,
must be used.
